Frequently Asked Questions

What is the article number for the IM 155-6 PN/2 HF interface module covered in this manual?
The article number is 6ES7155-6AU01-0CN0.
How many I/O modules can be connected to the IM 155-6 PN/2 HF?
The interface module supports a maximum configuration of 64 ET 200SP I/O modules plus 16 ET 200AL modules, with a maximum backplane bus length of 1 m (excluding the interface and server modules).
What PROFINET IO functions does the IM 155-6 PN/2 HF support?
The module supports real-time (RT) and isochronous real-time (IRT) communication, prioritized startup, device replacement without a programming device, media redundancy (MRP), shared device (up to 4 IO controllers), MSI/MSO, isochronous mode (min. 250 µs), system redundancy S2, PROFIenergy, configuration control, fail-safe modules, Multi Hot Swap, and Module-to-Module Communication (MtM).
What BusAdapters are compatible with the IM 155-6 PN/2 HF?
Compatible BusAdapters are: BA 2xRJ45, BA 2xFC, BA 2xLC, BA 2xSCRJ, BA SCRJ/RJ45, BA SCRJ/FC, BA LC/RJ45, and BA LC/FC. These support copper RJ45, direct bus cable connection (FC), glass fiber-optic (LC), and POF/PCF fiber-optic (SCRJ) connections.
What is the maximum I/O data length for the IM 155-6 PN/2 HF without system redundancy S2?
Without system redundancy S2, the maximum gross data length is 1440 bytes each for input and output data. The minimum guaranteed net data length without shared device is 933 bytes. For shared device with 2 IO controllers the gross limit is 1440 bytes in total; with more than 2 IO controllers it is 360 bytes per IO controller.
Which configuration software versions are required to use the IM 155-6 PN/2 HF?
The module can be configured via a GSD file (GSDML V2.3), via STEP 7 V5.5 SP4 with HSP 250/255, or via STEP 7 TIA Portal V15.1 or higher. Some functions such as Module-to-Module Communication (MtM) and system redundancy S2 to S7-1500R/H require TIA Portal as of V15.1.
What happens when the supply voltage falls below 19.2 V DC on the IM 155-6 PN/2 HF?
If the supply voltage falls below 19.2 V DC, an undervoltage diagnostics alarm is reported as incoming (Maintenance demanded). When the voltage subsequently rises above 20.4 V DC, the diagnostics alarm is reported as outgoing. This event also triggers the yellow MAINT LED on the interface module.
