Communications Using Rx, Ry, Rwr, And Rww - Mitsubishi Electric MELSEC iQ-R Series User Manual

Communications using RX, RY, RWr, and RWw

This allows data to be exchanged in units of bits and in units of words between the master station and device station.
• The remote station of the motion control station does not communicate data with the link device (RX, RY,
RWw, RWr) of the master station, and the motion function of the Motion module controls output and
acquires the input status.
<When using the PLCopen Motion control FB mode>
• When the Add-on baseSystem version is "1.18" or earlier, standard stations do not support communications
using RX, RY, RWr, and RWw. If a standard station is set in the Network Configuration Settings, "Network
parameter error (error code: 2221H)" occurs.
• The remote station of the motion control station can use the slave label to change output from ST programs
in the Motion module and the CPU module (public label), and obtain input status.
Master station and remote stations (standard stations)
■ Unicast mode
1:1 communications between the master station and each remote station (standard station). Remote stations do not
communicate with each other.
