Using ethernetIPforCLX with AB tag database
« on: July 17, 2020, 04:47:31 PM »
Ive been looking for the correct way to write a tag's value from an Allen Bradley Compact Logix to a component in VB. Currently I have been using the EthernetIPforCLX, inputting the IP address of the PLC, and using the Syntax (Program:MainProgram.TagName) in the place where I would typically put the modbus address of the tag. My issue is that when I run I get a PLC com error. Im not sure what my issue is, my only thought is that I would have to input the tag database but since I call the IP address of the PLC its seems redundant. Any help is appreciated.

If you are getting a Com error, then it's not the tag name. That would be a connection problem with the PLC.

If you use a BasicLabel, what is the exact error message that show up?

ERROR:= Address must be 4-11 digits Program:MainProgram.TagName

That is Modbus error and should indicate that you didn't replace the driver (ComComponent).
