Johnson Matthey Case Study

Leading speciality chemicals company relies on Cogent to replace an ageing control system in a tight shutdown window, as part of their obsolescence management program.

 

A legacy Allen Bradley installation of two PLC5s and a DH+ RSView station was replaced with a single Omron PLC processor and new InTouch application. The existing rack IO was re-terminated to Profibus DP SmartSlice remote IO nodes. All field instruments and MCC signals were then recommissioned during a very short production outage, before re-validating the controls sequences during process commissioning. The control software had been fully simulated on site with plant operations staff to minimise the training and familiarisation time during startup.
