Ladder Logic Example Program

The following ladder program is an example of the logic needed to
initiate explicit messages to the scanner/adapter/1769 I/O modules
and how to obtain the replies. Assume the 1747-SDN is in slot 3 and
the 1769-OF2 module is in 0A hexadecimal (10 decimal).

A copy of Data Table File N11 follows the ladder program to show the
location of the commands. The following program includes these
commands:

• Get 1769 I/O Module Configuration Size

• Set 1769 I/O Module Configuration

• Save 1769 I/O Module Configuration

• Get 1769 I/O Module Configuration
