The Human Machine Interface (HMI) - Accessories family of products lines is composed of various accessories necessary to build up user applications. The FC6A-PTS4 is a programmable terminal accessory among these accessories. It provides an interface from automation systems to the human operator. This article will provide an overview of the FC6A-PTS4 application field and working principle.

Application Field

The FC6A-PTS4 programmable terminal is suitable for use as an operator interface - normally in human-machine communication applications. It can also be used in the configuration and setup of the PLC integrated system, such as the Mitsubishi Electric FX series. Thanks to the built-in LED array, it is suitable for display of graphic data.

Working Principle

FC6A-PTS4 programmable terminal can display up to 160 characters in seven segments or 28 during continuous input. It is made up of an array of seven LED lamps, with each LED segment connected to a port of the MELSEC FX CPU (Central Processing Unit). The power supply for this LED array is derived from the MELSEC FX main base unit. The communication process involves LED lamps being turned on or off in response to signals sent up from the CPU via its ports.

When an operator enters data using an external switch or keypad, the signals are received by the ports on the CPU. This information is then processed by the CPU, and the corresponding LED lamps are illuminated. The operator is then able to view information on the displayed data. To provide feedback to the operator, there is the additional option of a buzzer being sounded in response to certain instructions.

Conclusion

The FC6A-PTS4 is an important component of the Human Machine Interface (HMI) - Accessories family of products and is typically used in the configuration and setup of the PLC integrated system, such as the Mitsubishi Electric FX series. It enables data entry and continuous input from an operator, providing an extensive and reliable user interface. In addition, the LED array allows for display of graphic data, increasing the usability of the programmable terminal.
