A programmable logic controller (PLC) may be used for the control of processes or any activity that requires high reliability control and ease of programming and process fault diagnosis.
Bath utilizes PLCs in control systems. They are easily programmable to replace hard-wired relays, timers and sequencers and are widely adopted as high-reliability automation controllers suitable for harsh environments. A PLC is an example of a “hard” real-time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result.
PLC output can include elements such as indicator lamps, meters, gauges, sirens, electric motors, pneumatic or hydraulic cylinders, magnetic relays, solenoids, or analog outputs.
Bath provides the programming of control loops for these control systems. Some large systems may have several hundreds or thousands of control loops. In complex processes the loops are interactive, so that the operation of one loop may affect the operation of another.
Systems are designed for supervision, data acquisition, control, historical archiving, trending, reporting, archive evacuation, and message capability. Integration includes electronic multifunction meters, digital relays, and controllers communicating with protocols such as DNP3, Modbus, and SEL Fast Messaging.
Bath has experience with a variety of HMI software applications including CopaData zenon, Wonderware System Platform, Wonderware InTouch, and SEL RTAC HMI.
