Data Communication Procedures - Mitsubishi Electric MELSEC iQ-RJ71EN71 User Manual

Data communication procedures

This section describes the procedure for communication with link-dedicated instructions.
1.
After the module parameters are set, check that the initial processing of the RJ71EN71 or the RnENCPU (network part)
has completed normally. ('Initial status' (Un\G1900024.0): On)
2.
Data is exchanged with link dedicated instructions.
Communication with the link dedicated instructions uses the MELSOFT transmission port (UDP/IP), so the
open/close processing is not required.
Setting procedure
1.
Set the network number and station number in "Own Node Settings" under "Basic Settings". ( Page 243
