B-20 Explicit Messaging Application Examples
The following ladder logic program is an example of the logic needed
to initiate an explicit message to the scanner/adapter/1769 I/O
module and how to obtain the reply. This logic is specifically for the
Get 1769 I/O Module Status command. Assume the 1747-SDN scanner
is in slot 3 of the processor chassis and the 1769-OF2 module that we
are reading status from is in slot 10 of the 1769-ADN remote system.
