Communicating with a
SLC 5/05 (1747-L552)
Controller and ControlNet
Scanner (1747-SCNR),
Unscheduled Messaging The Power Energy and Management Systems development team
tested the following example ladder. The scan times for execution of
the ladder are as follows.
All the communication operations of the ladder are locked out until
the read or write bits are set. This was done so that other operations
performed by the ladder will have minimum overhead from
communication. The following files are of importance when using the
ladder example.
Operation Scan Time
Table reads for Integer and float files 20 ms
Table writes of Integer and float files 30 ms
