ABB PM866AK01 Display Control Instrument

The advantages of the PM866AK01 have been well received by design and field technicians, and it has been widely used. Because the data of the display control instrument is mainly managed by the computer at the beginning, when developing the communication protocol of the display control instrument, the first consideration is the connection with the computer. Communication protocols between various display control instruments and PLC manufacturers are independent and not standardized. In order to connect the temperature controller and PLC, it is necessary to have the same communication interface and protocol for both. Write the communication program in the RS485 free port of the PLC.

The advantages of the PM866AK01 are summarized below.
(1) The burden on the PLC is greatly reduced;
(2) Realize the functions that PLC can not realize with the functions that the display control instrument has alone;
(3) Realize the control risk diversification;
(4) Sequence status and control data display status are simultaneously displayed on the touch screen or computer;
