Basic unit pm802f
The basic unit pm802f is composed of a metal rack and a CPU motherboard. It periodically scans the data from the
The signals of the field bus sensors are processed according to the control application program configured by the user, and then the calculation results are passed
The fieldbus interface card returns the corresponding fieldbus actuator.
Two field controllers can realize controller 1:1 redundancy, and undisturbed sw
