Operator panels, also known as Human Machine Interfaces (HMI) allow interaction between people (humans) and industrial control systems (machines) such as PLC – programmable logic controllers. They can be in various forms - text panels or graphical displays with touch screens. BESST Engineering at Queensland provides MECT Operator Panel with PLC that can help you monitor process critical information. The panel also enables operators to input instructions to check or change the commands to the machine being operated.
The MECT operating panels available with BESST Engineering are equipped with Modbus RTU over RS485 or CANopen, Modbus TCP, or TCPRTU on Ethernet interface. There is a micro USB port that is used for data logging and software update, or as a device for mass storage. For programs and data, an SD memory card can be installed on the operating panels. The panels come with their own software to configure the system and create PLC and HMI graphics applications without the need to write the code. Panels are available in portrait as well as landscape format.
The operator panel with PLC and touch screen can be used for a wide range of applications. Assembly lines, transportation, water treatment, food processing are only a few examples where operating panels with PLC can be used to automate processes. Operating panels with in-built input/output ports can help to monitor process critical variables and control systems by issuing commands to the system. Panels can link directly with a series of sensors and actuators, number of connections vary according to the model.
