I can't for the life of me figure out how to connect Visual Basic to a moellor PLC. All i want to do is monitor a pump station so any help you may have will be help full.
first of all, you need to install OPCServer that is included on the Moeller XSoft Cd. Then you need an ActiveX plugin to use in Visual Basic to interface with the PLC. The one I'm using is Metadynamics OPCClientX-AE
you can get sample programs from metadynamics for help.
if you have any other questions or want some more help, just let me know.
