2.3 Access Range for Monitoring
2.3.2 Network system (MELSECNET/H, MELSECNET/10) access range for monitoring
(1) Bus connection
(a) If connected to multi-PLC system
1) The control station on the network and all normal stations can be monitored.
2) The control station on the other network and all normal stations can be monitored.
(To monitor the other network, be sure to designate the routing parameter.)
3) When the monitor target is the multi-PLC system, CPU No. 1 to No. 4 can be monitored.
4) Devices of other stations (other than devices B and W that are allocated by the network parameter) may not allow monitoring depending on their PLC CPU.
Refer to Example 1 to 4.in (7).
The motion controller CPU (Q Series) at other stations cannot be monitored.
(b) If connected to QCPU(Q Mode)/QnACPU/AnUCPU
1) The control station on the network and all normal stations can be monitored.
2) The control station on the other network and all normal stations can be monitored.
(To monitor the other network, be sure to designate the routing parameter.)
3) If connected to an intermediate station and the data link system is included, the master station and local stations can be monitored.
4) If connected to an intermediate station, it is not necessary to designate the data link parameter ìEffective unit number for accessing other stationsî for the PLC CPU of the connected station. (If designated, the parameter will be ignored.)
5) Devices of other stations (other than devices B and W that are allocated by the network parameter) may not allow monitoring depending on their PLC CPU.
Refer to Example 1 to 4.in (7).
(c) If connected to AnACPU/AnNCPU
1) Control stations on the network can be monitored.
If the PLC CPU of the local station is QCPU (Q Mode)/QnACPU, devices other than B and W that are allocated by the network parameter cannot be monitored.
2) Normal stations on the network cannot be monitored.
3) Stations on the other network cannot be monitored.
(2) CPU direct connection/computer link connection (a) If connected to multi-PLC system
1) Access range is as described in (1) (a).
(b) If connected to QCPU (Q Mode)/QnACPU 1) Access range is as described in (1) (b).
(c) If connected to QCPU (A Mode)/AnUCPU
1) Control station on the network and all normal stations can be monitored.
When devices of other stations (other than devices B and W that are allocated by the network parameter) are monitored, monitoring is not available if the PLC CPU to be monitored is QCPU (Q Mode)/QnACPU.
2) If connected to an intermediate station, use data link parameter ìEffective unit number to access other stationsî to designate the unit number that is connected to the network to be monitored.

If the PLC CPU of the control station is QCPU (Q Mode)/QnACPU, devices other than B and W that are allocated by the network parameter cannot be monitored.
2) Normal stations on the network cannot be monitored.
3) The other network cannot be monitored.
(3) CC-Link connection (intelligent device station)/CC-Link connection (via G4)
• Connected stations can be monitored.
• When the connected station is the multi-PLC system, CPU No. 1 to No. 4 can be monitored.
• Other stations on the network system cannot be monitored.
Refer to (Example 6)
(4) When using MELSECNET/10 connection
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.
(a) The GOT is regarded as a normal station and monitors the control station and all normal stations on the network.
However, the device range that can be monitored depends on the communication unit/
communication driver mounted to/ installed in the GOT.
: Can be monitored.
: Can be monitored within the AnA device range as follows:
For timer (T), counter : access range of 0 to 255.
For file register (R, ER, ZR): cannot be monitored.
: Cannot be monitored.
If the monitoring target is a PLC CPU within a multiple CPU system, the control CPU of the network module can be monitored.
(b) The other network cannot be monitored.
(c) 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. Refer to (Example 5).
(5) Monitoring devices of other stations on network (Bus connection, direct connection to CPU, computer link connection)
If devices of other stations on the network system are monitored, display speed will be significantly reduced. Therefore monitor link relay (B) and link register (W) that are allocated by the network parameter.
