Transfer of the inputs¶
For the transfer to the CPU, the inputs of the CS31 modules are outputs of the CM574-RS in the CPU communication. For this reason, the input modules in the CM574-RS include IEC outputs (%Q).
The following table shows how the inputs of the CS31 modules are transferred and where the respective operands are located in the CPU:
| Inputs CS31 bus | CM574 - COM1 CS31 bus |
