CS31-Bus I/O configuration and access

The CS31-Bus is configured as described for the local interfaces AC500 CS31 Bus. The I/O mapping is done in exact the same way so that it is possible to access the CS31-Bus I/Os locally in the project of the AC500 CPU.

Note

When using the remotely controlled CS31-Bus in combination with a CM574-RS Communication Module the I/O area size for each port is restricted to 500 bytes input and 500 bytes output data (for local interfaces 1000 bytes in each direction are available). Automation Builder automatically calculates the configured I/O sizes and warns as soon as the available size has been reached.
