Pairing Open - Mitsubishi Electric MELSEC iQ-RJ71EN71 User Manual

Pairing open

Pairing open is an opening method that pairs a fixed buffer communication reception connection and send connection, and
establishes a connection using one port each from the own station and external device.
When pairing open is specified, data can be exchanged with two connections using an open processing for one port.
RJ71EN71 or RnENCPU (network part)
Connection No.1 Fixed buffer (for receiving)
Connection No.2 Fixed buffer (for sending)
Setting procedure
Set "External Device Configuration" under "Basic Settings". ( Page 244 External Device Configuration)
1.
Select the external device to be connected in "Module List" and drag it to "List of devices" or "Device map area".
2.
Set "Communication Method" for the external device.
3.
Set the "Fixed Buffer Send/Receive Setting" with the external device to "Pairing (Receive)".
4.
Set the other parameters required for communication in the connection.
5.
Select the same external device as step 1 from the "Module List", and drag to the next connection number of the external
device set in step 1.
6.
Set "Communication Method" for the external device to the same as the external device set in step 1.
7.
Set the "Fixed Buffer Send/Receive Setting" with the external device to "Pairing (Send)".
8.
Set the other parameters to the same values as the external device set in Step (1).
*1 Set "Pairing (Receive)" to connection No.1 to 7, or No.9 to 15.
• Only the external devices in the Ethernet to which the RJ71EN71 or the RnENCPU (network part) is
connected and devices connected via a router can communicate data with pairing open.
• The open/close processing for the next connection (send connection) is executed automatically using the
open/close processing on the receive connection side set to pairing open.
