Alarm
Four alarms (Alarm 1 to 4) can be specified on each channel.
Type
Select H, L, h (dH), l (dL), R (RH), r(RL) T, or t. The selectable alarms vary depending
on the input mode and computation type. For details, see section 7.2 of the CX User’s
Manual (IM 04L31A01-01E or IM 04L31A01-03E).
Value
Alarm is generated using the specified value as the boundary. The selectable range of
alarm values varies depending on the input mode and range.
Relay
Select the output relay number or internal switch number for outputting to relay output
or internal switches (Style 3 or later). When not outputting to relays or internal switches,
select NONE.
Detect
Select whether to display alarms (ON) or not to display alarms (OFF) when they occur.
When turned OFF, they are not retained in the alarm summary.
Alarm Delay
An alarm is generated when the measured value stays above or below the specified
value for the specified length of time.
Moving Average
To use the moving average, select the sampling count (2 to 16).
Tag
Use up to 16 alphanumeric characters to specify a tag.
You can select tags instead of channel numbers to be displayed on the screen.
To select whether to display channel names or tag names on the screen, select [AUX] >
[Tag/Channel] on the [Setup] tab.
If you select [Tag] in the [Setup] screen, you can select tag No., tag comment, or tag in
the Data Monitor or Data Viewer.

You can select the range of the screen in which the waveform of each channel is
displayed.
Specify positions (%) on the display scale for the upper and lower limits.
The conditions for setting the zones are as follows:
• Range: 0% to 100%
The lower limit must be less than the upper limit
• The difference between the lower and upper limits must be at least 5%.
