I/O Configuration

The module does not store configuration data itself. It gets its parameterization data from the master device of the I/O bus (CPU or bus module) during power-up of the system.

Hence, replacing I/O modules is possible without any re-parameterization via software.

Note

If the external power supply voltage via UP/ZP terminals fails, the I/O module loses its configuration data. The whole station has to be switched off and on again to re-configure the module.
