Requirements for using the "Enable CiR" option
● Use of an S7-400 CPU or an S7-400 H-CPU in single-station mode, each as of
firmware V3.1
● Internal DP interface of the CPU or CP 443-5 Extended (as of firmware version V5.0)
● The DP master must be configured in the DPV1 operating mode.
● ET 200M: IM 153 (as of 6ES7153-2BA00-0XA00)
You also need to equip the ET 200M with active bus elements and ensure sufficient
space for the planned expansion. You may not connect the ET 200M as a DPV0 slave via
the GSD file.
● ET 200iSP: IM 152 (as of 6ES7152-1AA00-0AB0)
You also need to provide sufficient space for the planned expansion and equip the
ET 200iSP with additional terminal modules and reserve modules.
● DP/PA link: IM 153 (as of 6ES7153-2BA00-0XA00)
● Compact FF Link (as of 6ES7655-5BA00-0AB0), FF Link (as of 6ES7153-2DA80-0XB0)
Recommendations for the properties of a CiR object
Take note of the size of the process image set in your CPU properties because, like all CPU
parameters, it can only be changed by an AS STOP. The future address lengths reserved in
the CiR objects must be within the process image size for inputs/outputs.
Preconfigured values of the CiR objects:
● On the DP master system: 15 slaves, 1220 input and output bytes
● On the PA master system: 6 slaves, 80 input and output bytes
