Because Pairing open is set to Enable, the next row will

automatically be set identically, except the Fixed Buffer will be set

to Send. Notice that each QJ71E71-100 can communicate with up

to 8 RMCs.

Opening a Connection on the Q-Series

Before the PLC can communicate with the RMC, the IP connection must be opened using

the ZP.OPEN instruction, described in section 10.8 of the Q Corresponding Ethernet

Interface Module User's Manual (Basic). Both connections of the pair (Send and Receive)

must be opened individually.
The port number must be 7171 hex (29,041 in decimal).

Closing a Connection on the Q-Series

To close the IP connection to the RMC, use the ZP.CLOSE instruction, described in section

10.5 of the Q Corresponding Ethernet Interface Module User's Manual (Basic). Both

connections of the pair (Send and Receive) must be closed individually.

Writing to the RMC with the Q-Series

Use the ZP.BUFSND Instruction to write to registers in the RMC. It is described in section

10.4 of the Q Corresponding Ethernet Interface Module User's Manual (Basic). The RMC

requires that the Send Data of the BUFSND instruction is in the format shown below.
