Siemens S5 to AB Controllogix Conversion
The Siemens S5 to AB Controllogix conversion involved upgrading the over 20-year-old S5 PLC which is obsolete to the ControlLogix. There were 5 PLCs that needed upgrading one at a time, but were connected to a Profibus network.
We created a way to semi-automatically convert the S5 PLC logic to ControlLogix, making the time for conversion much faster than doing it by hand. We also implemented ways to put the new PLCs in, while keeping the Profibus communications intact. When the final PLC was replaced, the whole network was replaced with Ethernet/IP.
