Frequently Asked Questions

What is PointMax I/O and how does it differ from POINT I/O (1734)?
PointMax I/O (Bulletin 5034) is Rockwell Automation's next-generation distributed I/O system, positioned as the successor to POINT I/O (Bulletin 1734). PointMax is EtherNet/IP-only at the adapter (no DeviceNet, ControlNet, or PROFIBUS variants), supports up to 32 I/O modules per adapter (vs 13-17 on POINT I/O), and natively supports intermix of standard, safety, and XT extended-temperature modules on the same mounting base. The mechanical assembly uses a separate Mounting Base (MB) + Removable Terminal Block (RTB) + I/O module rather than POINT I/O's terminal-base-plus-module design.
Why do some references call it Flex I/O?
Rockwell internal materials sometimes refer to the 5034 family as "Flex I/O" because of its modular, mix-and-match design philosophy. However, this is distinct from the legacy FLEX I/O family (Bulletin 1794) which has been in the catalog for over two decades. The canonical name for the new system is PointMax I/O, Bulletin 5034.
How many modules can I run on one PointMax adapter?
A single 5034-AENTR or 5034-AENTRXT EtherNet/IP adapter supports up to 32 I/O modules per system. The first 16 modules can be powered directly from the adapter (at 18-30V DC MP) or 8 modules (at 10-18V DC MP). Beyond 16 modules you must add a 5034-EXP or 5034-EXPXT expansion power module to provide additional MP current for the second bank.
What's the difference between standard and XT modules?
XT (Harsh Environment) variants include additional conformal coating and design considerations that provide greater protection against extreme temperatures, condensation, corrosive atmospheres, shock, and vibration. They carry ATEX/UKEX/IECEx Class I Division 2 / Zone 2 hazardous-location certifications with temperature code T4. Standard and XT modules can be mixed on the same mounting base when application conditions allow. Catalog numbers append XT (e.g. 5034-IB16XT is the harsh-environment variant of 5034-IB16).
Can I mix safety and standard I/O modules on the same backplane?
Yes — PointMax safety modules (5034-IB8S input and 5034-OB8S output) coexist with standard non-safety I/O on the same EtherNet/IP system. The safety modules use CIP Safety over EtherNet/IP and report to a GuardLogix safety task while standard modules report to the normal Logix task. A single 5034-AENTR adapter handles both message types.
What mounting base do I need?
Use 5034-MB for the standard 15 mm mounting base, or 5034-MBSA if the base needs to provide SA (sensor/actuator) power to downstream modules. XT variants (5034-MBXT, 5034-MBSAXT) are required when mixing with harsh-environment XT modules. Each I/O module also requires a removable terminal block (RTB) for field wiring — RTB18 (screw-clamp) or RTB18S (spring-clamp) for most modules; RTB24S for higher-density modules; RTBT/RTBTS for temperature modules.
Does PointMax I/O support Removal and Insertion Under Power (RIUP)?
Yes — every PointMax I/O module supports RIUP, so you can swap a module without de-energizing the system. The mounting base remains powered while the module snaps in or out. Automatic Device Replacement (ADR) restores the module's configuration when a replacement is installed, similar to POINT I/O.
What's the difference between the 5034-MBPTM and the 5034-EXP?
The 5034-MBPTM (Power Terminal Module) provides an additional SA (sensor/actuator) power rail to the backplane — it's used when your I/O modules collectively need more than 10 A of SA power, or when you want to segment SA power into separately-fused zones. The 5034-EXP (Expansion Power) provides additional MP (module power) and is required when running more than 16 modules per system. The two modules serve different power rails and can be used together.
