Posted 4 Nov 2022 Does anyone know of a way to programmatically see the I/O configuration of modules plugged into a PLC backplane similar to the "Read IO Config" button within RSLogix 500. I simply wish to see via ladder logic the model number of the Analog Input Card plugged into slot 11 of a SLC500 backplane. Share this post Link to post Share on other sites
Posted 8 Nov 2022 Unfortunately, Rockwell removed the Read IO feature when they went from 500 to 5000. There are several module status values that can be obtained with a GSV instruction, but the retrieving model/catalog number is not on the list. The best way to see what's in any given slot is RSLinx when offline. When online, of course, you just look a the properties dialog box. Share this post Link to post Share on other sites
