3. Communication targets
Between FX1S, FX0N, FX1N, FX2N, FX3G, FX3U, FX1NC, FX2NC, and FX3UC Series PLCs
4. Function
This network allows up to eight connected FX PLCs to automatically transfer data among the connected
PLCs.
In the network, data can be transferred among PLCs for devices determined in the refresh range, and those
devices can be monitored by every PLC.
5. Applications
By this network, data link can be achieved in a small-scale system, and the machine information can be
transferred between machines.
