We integrated a new control system to control the time/temperature setpoint for a vacuum furnace system. Using Wonderware InTouch HMI system and an Automation Direct PLC the operator controls the heat treating process for critical parts used for specialty tool steels. The following items were developed.
- HMI Display to edit/save and download temperaure/time setpoints to the control system
- HMI Interface to start/stop the vacuum process operation
- PLC communications to the PLC controller
- Realtime alarms for status of the process
- Realtime display of furnace temperature and vacuum setpoints and actual values
