7.8.3 General Response of the FCs for PROFINET IO
IO Consumer Status (IOCS) and IO Provider Status (IOPS)
The two communication partners - CPU/CP on the one hand and IO device on the
other - both have status information for the data (GOOD or BAD). This status
information is transferred parallel to the data. The status of the partner that sends
the data is called IOPS (IO Provider Status), the status of the receiving partner is
called IOCS (IO Consumer Status).
The IOPS and IOCS status are not necessarily identical. It is, for example,
possible that the S7-300 CPU is in STOP mode (output disable or no PROFINET
IO blocks active). In this case, the CP as PROFINET IO controller transfers the
BAD status to the IO devices.
