PLC Interface No. of CIO words allocated PLC → Unit: 1 word control data
Unit → PLC: 1 word status data
No. of DM words allocated Unit → PLC: 8 words of Unit setup information
Amount of I/O data per Unit Fixed:
2 words CIO area (one in, one out) for Unit status + control bits.
2 words status information from the host PLC, containing operation status and error code
(read from location A400). This information will be sent to the PROFIBUS master:
- as extended diagnostics, only at a change of data content.
- optionally, attached to the I/O data, each PROFIBUS cycle.
Variable:
2 user-defined areas for PROFIBUS I/O data, with the following restrictions:
- Up to 100 words input in one PLC area (CIO, H, D, EM).
- Up to 100 words output in one PLC area (CIO, H, D, EM).
- Inputs+outputs must be 180 words or less
