Description

technical field [0001] The invention belongs to the field bus communication field, in particular to a motion controller compatible with various field bus protocols. Background technique [0002] With the advancement of electronics and communication technology, industrial automation control has gradually developed from the traditional point-to-point analog or pulse signal control method to the full digital control of fieldbus. It integrates industrial field control, monitoring and other equipment in a communication network through serial signals, can build a field bus control system, and can establish an industrial information control management layer through a network protocol. The motion controller is the core of fieldbus control. It can be upwardly compatible with Ethernet to realize industrial network management, and downwardly compatible with the fieldbus network. Therefore, the fieldbus protocol compatible with the motion controller directly determines the flexibility o...
