NX/NJ protocol structure for Ethernet IP

[Kabil 0]

HI, 

Intention:

  We have NX701-1700 and NJ 101-1000 plc's and we want to do read/write  service with NX/NJ plc through ethernet IP protocol. 

Query 1:
    Will you please suggest the command which we can use for read and write job with NX/NJ and the command structure of the same.

Query 2:

      Will you please share Supported operands and their opcode's for NX701-1700 and NJ 101-1000. Please share the relevant manual document for NX and NJ through ethernetIP protocol.

Thanks

Kabil

Hi,

You can use tag data link, to cyclic communication. In this case you set up the controller to read the other device. See video:

Another option to use CIP. CIPOpen, CIPRead, CIPWrite, CIPClose instuction see in instructions reference. With this function block you can make the communication in code.
