RMC70/150 and RMCTools User Manual
Fixed Buffer: Receive
Fixed Buffer communication procedure: Procedure Exist
Paring open: Enable
Existence confirmation: Confirm
Host Station Port No.: 7171 hex (29,041 in decimal)
Transmission device IP address: Set this to the IP Address of the
RMC
Transmission target device Port No.: 7171 hex (29,041 in
decimal)
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.
