Platform hub

Rockwell and PLC control

Most Australian sites run Rockwell or mixed PLC platforms, and the work of programming, migrating and cutting over those systems has its own discipline. These guides cover PLC programming practice, reading a P&ID into control logic, batch structure and the planning and execution of an upgrade on a live plant.

The cluster links the PLC and control work Metromotion Controls delivers to the project case studies where legacy migration and commissioning were carried out without losing production.
