Input file MicroLogix

How do you address a tag to the input file of a MicroLogix?

Doing the ladder so the input mirrors a bit address is an option for me but I would like to read the input directly if possible.


I’m not sure exactly what information you are trying to read but inputs bits should show up in the OPC Browser that you can select from. Optionally, you can also type them in using the following format: [Micro 1400]I:0.0/00.

When it comes reading input words, only word 0 can be read. For example: [Micro 1400]I:1. Reading sub words such as [Micro 1400]I:1.3 from an analog or similar module is not supported with the Ignition MicroLogix or SLC drivers.


Okay, my syntax was incorrect.
