TPC has experience in applying and programming many major manufacturer’s programmable logic controller (PLC), operator interface terminal (OIT) and human-machine interface (HMI) supervisory control and data acquisition (SCADA) software packages.

The operator interface terminal (OIT) is your link to the controlled process via the PLC.  OIT options abound from a simple display with keypad to advanced color touchscreens. We take care to match your project’s requirements with a suitable unit that we configure to make it easy to operate.

SCADA systems with industry-standard communications protocols and HMI software packages provide comprehensive local and remote site control and monitoring.  System geographic and process loop graphic displays, alarm and event logging, reports, process control and process variable data logging functions are configured to your  specific project’s requirements.  As is the case with the OIT devices, we configure HMI software packages with ease of use and operator comprehension in mind.
