Get Diagnostic Status from Modules by Using Explicit Messaging
Appendix A
Get Status Messages from
1791ES-IB16 Modules
Follow these steps to get status messages from 1791ES-IB16 modules.
1. In the Module Definition dialog box, from the Input Status pull-down
menu, choose Combined Status.
This selection creates a three-byte input assembly, as shown, for the
1791ES-IB16 module.
2. Use the CombinedInputStatus bit to detect if one or more of the I/O
points on the module have a fault.
• If any input status bits go to a value of 0 (0 = bad; 1 = good), use an
explicit message to determine which individual data points have
faulted.
