Controlinc 1746-C (Version 5.21) Network Master Users Guide (2004-11-18)

Note 7: Once the 1746-C reads in a table from the M0 file, the 1746-C will always deliver the

feedback table almost immediately … whether or not it was a read or write table command.

Therefore, the best practice to maintain synchronization between the PLC and 1746-C is for the

PLC to “conceptually” wait for a feedback response from the 1746-C before continuing … even

if only to throw away the table.

This will also increase the 1746-C overall speed because it waits for an acknowledgement of

the feedback before continuing with command execution.

REMEMBER … Speed in servicing of the M1 transfer requests expedites system throughput.
