Replacement and Compatibility

An X‑COM 01 E module has more memory capacity than an X-COM 01 module. This is a

prerequisite for new protocols such as the PROFINET IO Controller V2.4+.

An X‑COM 01 E module can replace an X-COM 01 module installed in an existing system. To

ensure compatibility, observe the following points:

▪ The new X-COM 01 E module must be equipped with the same fieldbus submodules used

for the X-COM 01 module to replace.

▪ The X-COM 01 E operating system supports all protocols that were operated in the X-COM

01 module. Exception: PROFINET IO Controller V2.2. see Chapter 3.1.1.

▪ The existing X-CB 001 02 connector board can continue to be used with an X‑COM 01 E

module for all protocols. Exception: PROFINET IO Controller V2.4+.

▪ When using the PROFINET IO Controller V2.4+ protocol, the X-CB 001 04 connector board

is to be used instead of the X-CB 001 02 connector board.

Downgrade

If the PROFINET IO V2.2 protocol is to be used in an X‑COM 01 E module, then downgrade the

X‑COM 01 E module to an X-COM 01 operating system ≤ V14.12.

Refer to the maintenance manual for details on how to load operating systems.
