Retrofit Saves the Day for Boiler Cylinder Manufacturer

A MANUFACTURER OF BOILER cylinders needed a quick fix when an old Siemens S7-200 PLC broke down on a critical machine.

Westin Drives' engineers were quickly on site in Wakefield to repair the unit and have the company back in production the next day. To safeguard the machine's long-term operation, a retrofit of the PLC to non-obsolete parts was planned.

A Siemens S7-1200 PLC was selected, as this was the closest modern replacement to the original, along with a Unified 4in HMI. Westin's technical services engineers studied the machine's operation and prepared the new PLC program off-site to allow for a quick changeover.

The retrofit was undertaken in a morning's downtime, and the machine was back up and running in time for the afternoon shift to continue production. The customer was happy with the service, commenting that the new program saved time on each cycle of the machine, allowing more production throughput.
