CS31-Bus I/O Configuration and Access

The CS31-Bus is configured as described for the local interfaces Configuration of CS31 Bus Master. 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.
