Data Link System (Melsecnet/B, (Ii)) Access Range For Monitoring - Mitsubishi Electric GT1685 Connection Manual

3.4 Data Link System (MELSECNET/B, (II)) Access
Range for Monitoring

Bus connection, CPU direct connection, Computer link connection
(1) When connecting to the master station
• Local stations can be monitored.
When the PLC CPU of the local station is QnACPU, devices other than B
and W that are allocated by the link parameter cannot be monitored.
(2) When connecting to the local station
• The master station can be monitored.
However, when the PLC CPU of the local station is QnACPU, devices other
than B and W that are allocated by the link parameter cannot be monitored.
• Other local stations cannot be monitored.
(3) When connecting to the master station on the third layer
• The master station on the second layer and local stations on the third layer
can be monitored.
However, when the PLC CPU of the local station is QnACPU, devices other
than B and W that are allocated by the link parameter cannot be monitored.
• Local stations on the second layer cannot be monitored.

Monitoring devices of other stations
If devices of other stations on the data link system are monitored, the display speed will be significantly reduced.
Therefore monitor the link relay (B) and link register (W) that are allocated by the link parameter.
