Pastry Production Line Upgrade

General Mills, Berwick-upon-Tweed

The production line was controlled by an obsolete Siemens S5 PLC with cascade control of sixty drives. Line had failed PUWER assessment and required upgrade.

• Replaced the S5 PLC with latest Siemens S7-300 and MP277 HMI’s.
• Networked Siemens drives installed and cascade control achieved via user-friendly screens.
• Functional Safety achieved using AS-i Safe with machine guards and E-Stops connected to a number of AS-i Safety Monitors.
