Problem:
I have an Allen-Bradley PLC that I am trying to communicate with using my PC. However, I do not want to use OPC servers or the DSC module. What options do I have for connecting to my PLC in this case?

Solution:
Yes, you can connect to your Allen-Bradley PLC without using OPC servers or the DSC module using the following options:
