Precautions for cyclic transmission
When transmitting cyclic transmission with a GOT, even if link device X and/or Y are assigned to a GOT when
setting the network parameter for the control station, the GOT cannot access the host station.
When transmitting cyclic transmission, use link device B and/or W.
• The GOT is regarded as a normal station and monitors the control station and all normal stations on the
network.
When the monitoring target is a PLC CPU within a multiple CPU system, the GOT can monitor CPU No. 1 to
CPU No. 4 by specifying CPU No.
• When monitoring other networks, a CPU on another Ethernet, MELSECNET/H, MELSECNET/10, CC-Link IE
Controller Network, or CC-Link field network is accessible via the PLC CPU.
However, the GOT cannot monitor the CNC C70 on other networks.
On the Ethernet network, only QCPU (Q mode) and QnACPU can be accessed.
• When monitoring other networks in MELSECNET/10 connection, install the MELSECNET/H communication
unit on the GOT.
• To monitor other networks, setting of routing parameters is required.
For routing parameter setting, refer to the following manuals.

• If devices of other stations (other than devices B and W that are allocated by the network parameter) are
monitored, monitoring may not be available depending on the PLC CPU of the network system to be monitored.
