4 MONITORING SPECIFICATION
4.2 Monitorable Access Range and Device Specifying Method
4.2.1 Monitorable access range
The GOT can monitor only the remote inputs/outputs and remote registers (read/write
area) of the GOT assigned to the master station and the internal devices of the GOT.
The devices that can be monitored are indicated below.

1 Can be monitored only when the GOT-A900 Series is used.
2 n and m in the table indicate the addresses assigned to the master station by station number setting.
POINT
Dedicated command monitor is enabled for the GOT data registers (GD) only.
4.2.2 How to specify devices when creating the monitor screen
When creating the monitor screen, set the following devices as the devices to be
specified.
(1) Setting of NW number and PLC station number
Set "NW number to 0" and "PLC station number to host station".
(2) Setting of device names and device numbers
Set the following device names.
As the device numbers of the remote inputs/outputs and remote registers, set the
addresses assigned by station number setting.
