          Common Question:

          1.ModbusTCP common question:

          Q① : What is the default communication parameter for the module?
          A ① : The default IP of ModbusTCP module is 192.168.1.88, port number 502.
          Q ② : How to modify the module's IP address?
          A② : In the browser input module IP enters the backstage web page to modify IP.

          Q③: If forgot IP , how to restore IP?

          A③: In the case of power supply, dial the red dial key 2 to NO and reset, then restart after power failure. IP will revert to the default factory IP.
