3.1.3 Slave Polling Control and Status
Two arrays are allocated in the processor to hold the polling status of each slave
on the master ports. This status data can be used to determine which slaves are
currently active on the port, are in communication error or have their polling
suspended and disabled. Ladder logic in the processor can be written to monitor
and control the status of each slave on a master port. The objects used are
displayed below:
