CPU -> Unit: 1 word control data
Unit -> CPU: 1 word status data
Unit -> CPU: 8 words of Unit setup information
Fixed:
2 words CIO area (one in, one out) for Unit status + Software Switches.
1 word status information from the host CPU, containing operation status
and (see 3-8 CPU Status Information). 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 restric-
tions:
• Up to 100 words input in one CPU area (CIO, H, D, EM).
• Up to 100 words output in one CPU area (CIO, H, D, EM).
• Inputs+outputs must be 180 words or less
