Precautions

This section describes the considerations when the temperature control module is mounted on an extension base unit in a
redundant system with redundant extension base unit.
When configuring the temperature trace
Connect the engineering tool to the CPU module of the control system.
The engineering tool cannot recognize the temperature control module if it is connected to the CPU module of the standby
system.
Program examples
Unless otherwise specified, program examples provided in this manual and the following manual are for when the module is
used in the single CPU system or in the multiple CPU system.
MELSEC iQ-R Temperature Control Module User's Manual (Startup)
