Transfer of the inputsΒΆ

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:
