Gauge command priorities
The priority of the gauge command for NMS8x is very simple. The last received gauge command via
any sources will be executed to take of the former gauge command. However the priority varies
depending on the devices. When replacing the device with the NMS8x, check the priorities shown
below.
NOTICE
Undesired gauge command will be executed.
If the setting is not changed, an undesired gauge command will be executed (e.g. Level command via
Fieldbus would overwrite Stop command for maintenance.).
‣
If the system has been automatically or semi-automatically programmed for operation,
maintenance or other purposes, the setting should be changed corresponding to use.
