Hey Y'all, So I'm trying to connect Allen Bradley PLC (Control Logix).
I have the OPC topic setup and connected correctly. If i have a tag set to on when the machine loads then it stays in that state even when toggled in the program
vice versa if that tag is off when the machine loads it gets stuck in the off state.
I tried changing the polling rate but no good.
Does anyone have any advice ?
thanks Ham
Please check you have installed in your system the OPC Core Components Redistributable.
You can find the installer program in the USB Key (Software components folder) or here:
