Introduction
Parameterizable signal modules of the S7-300 product family mentioned in this
product information document can be reparameterized online using
STEP7 HWCONFIG in RUN mode of the CPU.
In other words, the module parameters can be changed without switching the CPU
to STOP mode or affecting other modules.
The following prerequisites must be met in order to use this function:
• STEP7 as of Version 5.2
• Distributed use of the S7-300 modules described in the S7-400 programmable
controller (CPUs as of V3.1 or CP 443-5 extended as of V5.0).
• Use of the ET 200M with the IM 153-2 as of 6ES7153-2BA00-0XB0 or
6ES7153-2BB00-0XB0
• Use of the IM 157 as of 6ES7157-0AA82-0XA00
You will find a detailed description of the prerequisites and principles of operation in
the manual Modifying the System during Operation via CiR
