Control system for the capture of drinking water

Nivek Automations is currently completing an emergency automation project in a drinking water plant. Following a thunderstorm, the control system, which was scheduled to be replaced next year, gave in as the technologies used (DeviceNet and Omron NSJ controller), were no longer up to date. Therefore, we replaced the part of the system damaged by newer technologies. Everything was done in an emergency matter.
The architecture of the system was quite complex, we had to exchange data with 3 PLC Omron CJ1M CPU13 and also communicate with 2 existing Phoenix Contact PLC for the supervision software data.

The option chosen was to install a PLC Phoenix Contact ILC 350 PN Profinet in order to replace the DeviceNET part.

For the supervision, we opted for the MJ solution, since the architecture was no longer a problem, we could focus on the programming rather than the design.
Since the MJ is also a virtual PLC, all programming of the local system is done in the Software, the PLC serves as a link to the inputs / outputs, we would have gone with a PLC-free solution with only network inputs / outputs, but given the very short delivery delays, we could not take any risks and move towards a solution already implemented a dozen times in the last year.
