The production planning and process recipes are contained in a MS Access database. This is accessible on a Windows for Workgroups peer-to-peer network from the Process Engineer’s PC. Wonderware allows ODBC access to the database to download the order information and the control setpoints directly to the AB PLC 5/20.
All operator controls were via touchscreen with the exception of Emergency Stop. Control popup and ramp keys facilitated operation of the line.
This is an international project that required working with a version of Windows for Workgroups in Arabic. All operator screens were composed in French, as this is one of Lebanon’s official languages.
Subsequent projects include French screens in Quebec and training for operators en Français.
