Setting the Alarm List Display Function (Setting the Bit Memory Table)
When the alarm list display function is used, it is necessary to set the bit memory
table and screen display function. This paragraph describes the setting of the bit
memory table. For the display setting, refer to NT-series Support Tool
Operation Manual” (V028-E1-01).
In order to set the message to continuous or duplicate screen, only the first sub-
screen is effective.
In one alarm group, the bit memory tables less than continuous 128 can be used

table number, the higher the order of priority a massage has.

is assigned is recorded.
