EtherCAT PLC and Servo Drives | Wecon Motion Control

[@WeconTechnology]

Correction - At the 7.34 timestamp, We used Ethercat Protocol but we mentioned Modbus. Please consider it Ethercat. The servo drivers are connected to the PLC in series one by one through the network cable. The number nearest to the PLC is 0, which is 1, 2,.... 31 in sequence (the numbering method is the same as that of the PLC module) Then configure each servo in the PLC software, and finally control the servo movement through the program.

Is the communication protocol Modbus RTU or is it Modbus TCP/IP?

[@WeconTechnology]

it is ethercat protocol

[@xiacaustralia]

@@WeconTechnology But the drives are assigned via MODBUS protocol (as demonstrated in this video), so the modbus runs over ethercat?

[@WeconTechnology]

@@xiacaustralia sorry, not modbus

[@xiacaustralia]

@@WeconTechnology In the video at 8:00 there is clearly a MODBUS communication module in the PLC program, so this is only for comparison, is it? It is not used when using ethercat?

@@xiacaustralia yes, a mistake, it is ethercat, no need modbus communication to control the servo. the servo parameters are configured in the PLC, and then the motion control command is used to control the servo operation.
