Ask to modify the controls to an automated 300 tonne silo feed transfer system. The original control system is about 5 years old (designed, built and installed by us) and the customer requires a new dust removal system to be added.
Had the job of removing an old Siemens S5 control panel for a plastics extruder and replacing with a new modern Allen Bradley PLC and Panelview Plus HMI Screen. New modern SSD DC 690+ drives on Devicenet and Siemens Solid State Switches for the heaters. New panel was tight as the customer wanted extras so we did a back to back job between the steel work !
