Troubleshooting Appendix A
4. Select a flag write tag and right-click on the tag name.
5. Select Monitor Tag from the menu.
This should be a rack flag write tag pertaining to a rack that has
a SIM Module. SIM modules simulate inputs and outputs and
will indicate where data is being written to and read from.
6. Enter data in the Tag Monitor window and see how that data
matches the indicator lights on the SIM module.
For observing Flag read data, flip the switches on the SIM
module and see how that change affects a flag read tag for that
rack
7. Put the controller in Run Mode or uncheck Inhibit Module.
8. Verify that the correct data is being written to the 1757-ABRIO
module from the controller using the same tag monitor screen in
AbRioCfg software.
9. Verify that data is being written correctly from the 1757-ABRIO
module to the controller by observing flag read data within
RSLogix 5000 software (ControlLogix controller) or Control
Builder software (ProcessLogix controller).
10. Also, read SIM module switches from the controller.
If you are using message instructions in RSLogix 5000 software
to read this flag data, remember to append the tag name with
the [100] offset. See
Unscheduled I/O Connections in
ControlLogix on page 67 for more details.
IMPORTANT
To write data, you have to enable writes, using either the menu
item Edit/WriteEna or using the Toolbar button.
