Hi, I’m trying to add tags to ignition using the OPC browser, but it fails to display tags inside of a PD file inside of a MicroLogix 1100 PLC. For example, I want to access PD145:0.SPS. I’ve tried creating the tag by hand and typing the address into the OPC item path, but I get a little red x on that tag in the browser.

Is there a way to access a PD file, or am I going to have to map to some other type of file?

Thanks,  
~Ryan

Currently our drivers do not support PD file type for MicroLogix, SLC or PLC-5 devices.

It is on our list but is a lower priority.

Thank you,
