1. Panel Overview
The TP900 Comfort is a touch-only Comfort Panel with a 9" widescreen TFT display. It sits in the middle of the Comfort family between the smaller 7" TP700 Comfort (6AV2124-0GC01-0AX0) and the larger 12" TP1200 Comfort (6AV2124-0MC01-0AX0). The panel is intended for stationary panel-mount installation in a control cabinet or operator console — it is not a mobile/handheld device and is not field-portable.
Per the manual scope of delivery (page 15) the device ships with the panel itself, a Quick Install Guide, 16 aluminum mounting clips with grub screws, and a 24 V DC plug-in power supply connector. Memory cards (SIMATIC HMI Memory Card 6AV2181-8XP00-..., USB stick 6AV6881-0AS42-...) are ordered separately.

Compared with the TP700 and TP1200 Comfort
On the Comfort Panel spec table, only the display size, weight, and power consumption change between the 7" / 9" / 12" touch siblings — the 12 MB application memory, MMC/SD + SD slots, dual RJ45 PROFINET switch, RS422/485 PROFIBUS port, USB host/device, line-out audio, and 24 V DC power input are identical across TP700 / TP900 / TP1200. The TP900 sits at 800×480 resolution; the TP1200 jumps to 1280×800.
3. Hardware Layout & Interfaces
The TP900 Comfort has a frameless touch front, a metal rear enclosure, and a rear interface bay that lines up along the bottom edge of the device. There are no function keys, no labeling-strip slots, and no keyboard — everything is touch driven.
Rear-Side Interface Layout (page 21)
| Label | Interface | Specification |
|---|---|---|
| X80 | DC 24 V power input | 2-pin plug-in connector. Pin 1 = +24 V DC, Pin 2 = GND. Mating plug is supplied with the device. |
| FE | Connection for functional ground | Threaded stud next to X80; must be tied to cabinet ground bar. |
| X2 | PROFIBUS DP (RS422/485) | 9-pin Sub-D socket (female), max. 12 Mbps. Doubles as RS422 or RS485 to third-party controllers. |
| X1 | PROFINET (LAN) port 1 | RJ45, 10/100 Mbps, with integrated switch. |
| X1 | PROFINET (LAN) port 2 | Second RJ45 of the integrated switch (one IP address only). Used to daisy-chain to the next device. |
| X61 / X62 | USB type A (USB 2.0 host) | Two USB host ports, 5 V / max. 500 mA each. Used for memory stick, keyboard, mouse, printer, SITOP UPS. |
| X60 | USB type Mini-B (USB 2.0 device) | Used for direct PC-to-panel transfer when no Ethernet is available. |
| X90 | Audio Line OUT | 3.5 mm stereo jack: pin 1 L, pin 2 R, pin 3 GND. |
Both PROFINET RJ45 ports share one IP address
The two RJ45 ports on X1 are an internal Ethernet switch — the panel exposes only one IP address. Use port 2 to daisy-chain to another PROFINET node; do not configure two separate IP addresses on the panel. (Manual page 220, footnote on the PROFINET row.)
Mechanical dimensions (page 209)
| Dimension | Value |
|---|---|
| Front-bezel width | 274 mm |
| Front-bezel height | 190 mm |
| Build-in depth | 63.1 mm (housing) / 69.3 mm (housing + clips) |
| Mounting cutout (W × H) | 249 × 164 mm (per page 209 dimension drawing) |
| Approved mounting position | Landscape vertical (default), landscape inclined ≤ 35°, portrait vertical, portrait inclined ≤ 35° |
Indoor use only — rear is IP20
The Comfort Panels manual section 2.4 (page 29) states the device is approved for indoor use only and that the rear panel is IP20. The cabinet or console housing the panel is what provides protection against contact, dust, and the spread of fire — the front IP65 rating only applies after the panel is properly mounted with the gasket flush against the cutout.
4. Mounting in a Control Cabinet
The TP900 is panel-mounted from the front of the cabinet door or console and clamped from behind with the supplied aluminum mounting clips.
- Cut the panel cutout. Match the dimensions in the dimension drawing on page 209: 249 mm wide × 164 mm tall for the TP900. File or grind the edges smooth so the gasket can sit flat.
- Verify the gasket is in place. The mounting seal sits in the rear groove of the bezel. The IP65 / Type 4X front rating only holds when the seal lies flush and undamaged against the cutout (manual page 200).
- Insert the panel from the front. Slide the device into the cutout until the bezel sits flush against the cabinet face.
- Insert mounting clips into the side cutouts. The TP900 ships with 16 aluminum mounting clips (manual page 15). Hook each clip into the cutout in the side of the housing — there are clip slots along the top, bottom, and both sides.
- Tighten each clip. Drive the grub screw on each clip until the lip pulls the bezel snugly against the cabinet from the rear. Do not overtighten — you will deform the housing.
- Connect functional ground. Run a low-impedance braid from the FE stud next to the X80 connector to the cabinet ground bar. Functional ground is required for noise immunity and for the EMC declarations on page 196 to apply.
- Verify clearance. Leave room around the device for the rear interface plugs and for airflow. The build-in depth is 63.1 mm and the rear bay extends another ~6 mm with cables attached.
Mounting position determines max ambient temperature
Per the operating-conditions table (page 198): in the standard landscape, vertical orientation the TP900 is rated to 0…50 °C. If you tilt it (landscape inclined up to 35°) or rotate it to portrait, the upper limit drops to 40 °C. For portrait inclined ≤ 35° it drops to 35 °C. Plan cabinet airflow accordingly.
5. Power Wiring (X80, 24 V DC)
The TP900 runs from a single SELV/PELV 24 V DC supply — the same supply you would use for an S7-1200 or S7-1500 PLC, ET 200SP head module, or LOGOPower module is appropriate.
| X80 Pin | Signal | Connect To |
|---|---|---|
| 1 | +24 V DC | +24 V output of a SELV/PELV supply |
| 2 | GND (0 V return) | 0 V rail of the same supply |
SELV / PELV supply is mandatory (manual section 2.4, page 29)
“The device is intended for operation in an SELV/PELV circuit according to IEC/EN 61131 or IEC/EN 61010-2-201 in a dry environment.” A standard load-rated 24 V DC industrial supply (SITOP, PULS, Phoenix QUINT, etc.) satisfies this. Do not power the panel directly from a non-isolated rail or from a higher-voltage bus.
Power-supply sizing
Plan the supply against these numbers from page 220:
| Parameter | Value |
|---|---|
| Permitted voltage range | 19.2 … 28.8 V DC |
| Rated current | 0.75 A |
| Rated current (load-dependent, min…max) | 0.75 A … 1.05 A |
| Inrush current | 0.5 A²s (I²t) |
| Maximum permitted transient | 35 V (500 ms) |
| Minimum time between two transients | 50 s |
| Power consumption | 18 W |
Why 1.05 A and not 0.75 A?
The 0.75 A figure is the typical draw at 24 V DC. The maximum 1.05 A is what the panel can pull when it is simultaneously driving USB peripherals (X61/X62 deliver 5 V at up to 500 mA each) and at the lower end of the input voltage band. Size the supply for the 1.05 A figure with at least 25% headroom — a 1.5 A or 2 A SITOP-class output is appropriate.
Hazardous-area users: do not hot-plug X80
Per the Class I, Division 2 / Zone 2 warning on page 31, “Do not disconnect while circuit is live unless area is known to be non-hazardous.” In Ex installations, switch off the cabinet and verify the area is safe before pulling the X80 power plug or any USB / SD media.
6. PROFINET / Ethernet Wiring (X1)
X1 is a 10/100 Mbps RJ45 socket with an integrated 2-port switch. Both ports share one MAC and IP address — you can daisy-chain another PROFINET node off port 2 without an external switch.
| RJ45 Pin | Signal | Description |
|---|---|---|
| 1 | Tx+ | Data output + |
| 2 | Tx− | Data output − |
| 3 | Rx+ | Data input + |
| 4 | NC | Not assigned |
| 5 | NC | Not assigned |
| 6 | Rx− | Data input − |
| 7 | NC | Not assigned |
| 8 | NC | Not assigned |
Cable selection for PROFINET
Use Siemens FastConnect green PROFINET cabling (e.g. SIMATIC NET PROFINET cable type FC TP Standard, 6XV1840-2AH10) or an equivalent Cat 5e SF/UTP industrial cable terminated with shielded RJ45 plugs. Keep runs under 100 m segment length and bond the cable shield at both ends through the metal RJ45 plug body. See the FastConnect assembly note
6GK1901_FastConnect_assembly.pdf already in the PLCX library.
Insulation test voltage on the Ethernet port (page 200)
Section 8.6 lists the type-test insulation voltage on the Ethernet connector at 1500 V AC. That is the production type-test value — do not hi-pot a deployed panel at that level. The relevant takeaway: the PROFINET port is galvanically isolated from the 24 V DC input and from chassis ground.
7. First Power-On & Control Panel Commissioning
After the device is mounted and 24 V DC is applied, the panel boots into the SIMATIC HMI Start Center. From there you reach the Control Panel, where you set IP address, region, time, password, screen saver, and transfer mode before the first project download.
- Apply 24 V DC. The bootloader logo is shown briefly, then the Start Center screen appears with three buttons: Transfer, Start, and Settings.
- Open the Control Panel. Tap Settings → Control Panel. From here you can open every dialog described below.
- Calibrate the touch screen if needed. Open OP Properties → Touch tab → Recalibrate. Touch the crosshair at each position with a touch pen until the panel displays the “New calibration settings have been measured” confirmation, then tap once within 30 s to save (manual section 4.3.5.6, page 91).
- Set the date / time / time zone. Open Date/Time Properties. Pick the time zone, press Apply, then set the wall-clock time. Tick “Daylight savings time currently in effect” if applicable. The system does not auto-switch DST — toggle this checkbox manually each spring/fall (manual page 95).
- Set the region / language. Open Regional and Language Settings, choose the locale, then walk through the Number / Currency / Time / Date tabs to lock in the format conventions.
- Configure transfer mode. Open Transfer Settings → General tab. For first-time download choose Automatic and enable the PN/IE transfer channel. After commissioning, change this to Manual or Off to prevent unintended overwrites of a running project (manual page 100).
- Lock the Control Panel. Open Password Properties and set a password. This enables “SecureMode” — a tamper protection that requires the password to enter the Control Panel, taskbar, or desktop (manual page 96).
Do not lose the Control Panel password
Manual page 96: “If the password is no longer available, the following operator controls are no longer enabled: Control Panel, Taskbar, Desktop. All data on the HMI device is deleted when you update the operating system!” Treat this password the same way you treat the maintenance password on a CompactLogix or S7-1500 controller: store it in your maintenance vault, not on a sticky note.
Use a screen saver to extend backlight life
Page 98 of the manual recommends activating the Standard (Flying Windows) screen saver to prevent burn-in. The MTBF for half-brightness is 80 000 h — about 9 years of 24/7 operation — and dimming via timer or PROFIenergy meaningfully extends that. Open ScreenSaver, set an activation period in minutes, and pick the Standard or Standard with Dim Backlight option.
8. Setting the IP Address & Naming the PROFINET Device
PROFINET projects address the panel by device name rather than IP. TIA Portal assigns the name during the project transfer using DCP (Discovery and Configuration Protocol). You still need a valid IP on the panel for the initial reachability.
- Plug in the configuration PC. Patch the engineering PC to PROFINET port 1 of X1, or to a switch shared with the panel.
- Open the Internet Options dialog on the panel. From the Control Panel, tap WinCC Internet Settings or Network and Dial-up Connections.
- Set the IP address. Two choices:
• Obtain an IP address via DHCP — appropriate when a DHCP server is on the network.
• Specify an IP address — type a fixed IPv4 address, subnet mask, and (optional) default gateway. Use a static address whenever the panel is part of a deterministic PROFINET IO line. - Confirm with OK. The new address takes effect immediately; no reboot is required for IP changes.
- Verify reachability from TIA Portal. In the Project tree open Online access → your PG/PC interface → Update accessible devices. The panel should appear by name and IP. If it does not, double-check the X1 link LEDs (top-right and top-left of the RJ45 jack) and that you patched into port 1 not port 2 of a daisy chain.
Renaming a device the TIA way
TIA Portal sets the PROFINET device name during “Assign device name” in the project tree, not on the panel itself. The panel's local name field can be left empty — the project assignment overwrites it. The device-name string must follow PROFINET naming rules (lowercase, digits, hyphens; no underscores).
9. Transferring a Project from TIA Portal (WinCC Comfort/Advanced)
The TP900 Comfort is configured with WinCC (TIA Portal) V11 or higher. WinCC Basic does not support Comfort Panels — you need at minimum WinCC Comfort or WinCC Advanced. From V14 SP1 onwards, the panel image carries a digital signature that the runtime can validate (manual page 101).
Project transfer over PROFINET (PN/IE)
- Add the device to your TIA project. In the Devices tree, Add new device → HMI → SIMATIC Comfort Panel → 9" Display → TP900 Comfort. The article number on the device card matches 6AV2124-0JC01-0AX0.
- Connect the panel to the PLC. Drag a wire from the panel's PROFINET interface to the controller's PROFINET interface in Devices & Networks. The default connection driver is SIMATIC S7-1500, S7-1200, S7-300/400, or S7-200 depending on the controller (manual section 8.11, page 232 lists every supported driver).
- Compile. Right-click the HMI device → Compile → Hardware and software (only changes). Resolve any errors before downloading.
- Set the panel's transfer mode to Automatic. On the panel: Control Panel → Transfer Settings → Automatic, with the PN/IE channel ticked. (Manual section 4.3.6.5, page 100.)
- Initiate download. In TIA: right-click the HMI device → Download to device → Software (all). Choose PN/IE as the PG/PC interface, search the subnet, select the panel, and click Load. The runtime closes any running project, accepts the new image, and restarts.
- Verify on the panel. The new project starts after the configured Start Center delay (default 3 s, configurable up to 60 s; manual page 103).
Watch out for “Validate Signatures”
If the panel's HMI image is V14 or newer and the project is compiled against an older image, the runtime will reject the unsigned transfer and display an error. Either upgrade the panel image to a matching version or, if you are intentionally downloading an older signed image, untick Validate Signatures in Transfer Settings first (manual page 101).
Secure HMI Communication (TIA V17+)
From TIA Portal V17 onward the panel supports Secure HMI Communication — an encrypted, certificate-authenticated link between the Comfort Panel and S7-1500 / ET 200SP controllers. The TIA Portal generates the PLC communication certificate; on first connect, the panel quarantines it under
\flash\simatic\SystemRoot\OMS\Untrusted. Move it to \OMS\Trusted using the panel's file manager and restart the runtime to complete the trust handshake (manual page 234).
10. Field Diagnostics
The TP900 has no LEDs on the front bezel — status is read from the screen itself, from the RJ45 link/activity LEDs on X1, and from the Control Panel diagnostics dialogs.
Common symptoms and resolutions
| Symptom | Likely cause | Resolution |
|---|---|---|
| Display is blank, panel does not boot | No 24 V DC, polarity reversed, supply outside 19.2–28.8 V, or X80 plug not fully seated | Measure across X80 pin 1 (+) to pin 2 (GND); reseat the plug; verify the supply is sized for at least 1.05 A |
| Boots to Start Center but never starts the project | Start Center delay set to Forever, or no project loaded | From the Start Center, tap Settings → Transfer Settings → Directories tab and lower the Wait time to 1, 3, 5, or 10 s (manual page 103). Re-download the project if missing. |
| Touch is offset (parallax) | Calibration drift after relocation or re-mounting | Open OP Properties → Touch tab → Recalibrate. Use a touch pen, hit each crosshair dead-center (manual page 91). |
| TIA Portal cannot find the panel on the network | PG/PC patched into wrong subnet, or panel is in Off transfer mode | Verify the X1 RJ45 link LED is solid; confirm the panel IP is on the same subnet as the PG/PC; in the Control Panel set Transfer Settings → Automatic and re-enable PN/IE. |
| Communication fault to non-Siemens PLC | PROFINET IO services enabled while talking to Modicon, Allen-Bradley DF1, or Mitsubishi FX | Manual page 232 footnote: disable PROFINET IO in Control Panel before using these drivers, or the panel will report communication errors. |
| Date/time has drifted after several weeks of power-off | RTC battery exhausted (typical buffering 6 weeks per page 221) | Reset date/time in the Control Panel; consider configuring NTP under Date/Time settings if the panel is on the corporate network. |
| Display fades or burns in | Same image left on screen for days/weeks | Activate Standard (Flying Windows) screen saver in ScreenSaver dialog (manual page 98). Use Dim Backlight option to reduce backlight to 25–90% during idle. |
| Memory-low warning during runtime | Project too large or too many alarms in retentive buffer | Open OP Properties → Memory Monitoring tab; tick Shut down HMI Runtime if memory is running low (manual page 104). For chronic alarms, deactivate retentive alarm buffer in Message Buffer tab (page 105). |
Reading firmware and image version on the device
Open OP Properties → Device tab. The dialog shows the device name, image version, bootloader version + release date, flash size, and MAC address (manual page 93). Quote those four numbers when you open a Siemens support ticket.
11. Comfort Panels Family Comparison
The Comfort Panels family spans 4" through 22" displays, with each size offered as either a Key (KP), Touch (TP), or 4" combination KTP variant. The TP900 sits in the middle of the touch line. The article numbers are listed on page 3 of the manual.
| Model | Article number | Display | Resolution | Operation |
|---|---|---|---|---|
| KP400 Comfort | 6AV2124-1DC01-0AX0 | 4.3" widescreen TFT | 480 × 272 | 8 function keys + numeric keyboard |
| KTP400 Comfort | 6AV2124-2DC01-0AX0 | 4.3" widescreen TFT | 480 × 272 | Touch + 4 function keys |
| KP700 Comfort | 6AV2124-1GC01-0AX0 | 7.0" widescreen TFT | 800 × 480 | 24 function keys + keyboard |
| TP700 Comfort | 6AV2124-0GC01-0AX0 | 7.0" widescreen TFT | 800 × 480 | Touch only |
| KP900 Comfort | 6AV2124-1JC01-0AX0 | 9.0" widescreen TFT | 800 × 480 | 26 function keys + keyboard |
| TP900 Comfort | 6AV2124-0JC01-0AX0 | 9.0" widescreen TFT | 800 × 480 | Touch only — this guide |
| KP1200 Comfort | 6AV2124-1MC01-0AX0 | 12.1" widescreen TFT | 1280 × 800 | 34 function keys + keyboard |
| TP1200 Comfort | 6AV2124-0MC01-0AX0 | 12.1" widescreen TFT | 1280 × 800 | Touch only |
| KP1500 Comfort | 6AV2124-1QC02-0AX0 / -1QC02-0AX1 | 15.4" widescreen TFT | 1280 × 800 | 36 function keys + keyboard |

| TP1900 Comfort | 6AV2124-0UC02-0AX0 / -0UC02-0AX1 | 18.5" widescreen TFT | 1366 × 768 | Touch only |
| TP2200 Comfort | 6AV2124-0XC02-0AX0 / -0XC02-0AX1 | 21.5" widescreen TFT | 1920 × 1080 | Touch only |
When to step up to the TP1200, and when to step down to the TP700
If your application has more than ~12 simultaneous on-screen objects per screen, or you need to display trends with multiple Y-axes side-by-side, the TP1200's higher 1280×800 resolution and 24 MB application memory pay back. If your operator station is just a few buttons and a status indicator on a small machine, the TP700 saves cost without losing any of the PROFINET / WinCC capability.
Mobile / handheld panels are a different family
The Comfort Panels in this table are stationary panel-mount devices. If you need a handheld walk-and-monitor panel with an enabling button and emergency-stop — for machine commissioning or guarded-zone access — you want the SIMATIC HMI KTP700 Mobile family (e.g.
6AV2125-2GB03-0AX0) which has a different connection-box architecture and a different operating-instructions manual.
12. Supported Controllers and Drivers
The TP900 Comfort is supported by every standard SIMATIC PLC line-up plus a long list of third-party controllers (manual page 232). Up to 8 simultaneous PLC connections can be established (the smaller KP400/KTP400 are limited to 4).
| Controller | Supported on TP900 Comfort |
|---|---|
| SIMATIC S7-1500 | Yes — preferred, supports Secure HMI Communication on TIA V17+ |
| SIMATIC S7-1200 | Yes — preferred, supports Secure HMI Communication on TIA V17+ |
| SIMATIC S7-300 / S7-400 | Yes |
| SIMATIC S7-200 | Yes |
| SIMATIC HTTP protocol | Yes |
| LOGO! | Yes |
| Allen-Bradley EtherNet/IP | Yes |
| Allen-Bradley DF1 | Yes — PLC 5 requires KF2 module or 6AV6671-8XE00-0AX0 RS422-RS232 converter; PROFINET IO must be disabled |
| Mitsubishi MC TCP/IP | Yes |
| Mitsubishi FX | Yes — PROFINET IO must be disabled |
| Modicon Modbus TCP/IP | Yes |
| Modicon Modbus RTU | Yes — PROFINET IO must be disabled |
| Omron Hostlink | Yes — PROFINET IO must be disabled |
“PROFINET IO must be disabled” rule
If you are talking to Mitsubishi FX, Modicon Modbus RTU, or Omron Hostlink, leave the PROFINET services checkbox in the panel's Control Panel unchecked. Otherwise the panel inserts itself into the PROFINET DCP scan and these third-party drivers will throw communication errors (manual page 232).
