• Number
Set the output relay number when performing relay output.
The selectable output relay numbers are as follows.
• When outputting the signal from the [ALARM] terminal of the measurement alarm
output terminal block
I01 to I06
(Displayed even when none of the “/A6, /A6R, /A4F, and /A4FR” options of the
measurement alarm output terminal block is specified.)
• When outputting the signal from the [DIGITAL OUT] terminals 1 to 6 of the control
output terminal block
DO001 to DO006 (Contact output of loop 1 and 2 control output terminal block)
DO101 to DO106 (Contact output of loop 3 and 4 control output terminal block)
DO201 to DO206 (Contact output of loop 5 and 6 control output terminal block)
(If some of the control output terminal blocks are not installed, the relay numbers
for those terminals are not displayed.)
• When outputting the signal from the [DIGITAL OUT] terminals 1 to 12 of the control
DIO expansion terminal block
RO001 to RO012
(Only displayed when the control DIO expansion terminal block option “/CST1” is
specified.)
• When outputting to the internal switches (SW001-SW36), select from SW001-
SW036 (style number S3 or later).
Note
• The terminals that can be set to alarm outputs are referred to as relay outputs in the
settings. Actually, two types of terminals can be set to alarm outputs: relay output terminal
and transistor output. Only [ALARM] terminals 1 to 6 of the measurement alarm output
terminal block and [DIGITAL OUT] terminals 1 and 2 of the control output terminal block
are relay outputs.
• In addition to alarm outputs of measurement/computation channels, the following outputs
can also be assigned simultaneously to the [DIGITAL OUT] terminals of the control output
terminal block and [DIGITAL OUT] terminals of the control DIO expansion terminal block
• Control alarm
• FAIL (only the [DIGITAL OUT] terminal 1 of the control output terminal block)
• Self diagnosis (only the [DIGITAL OUT] terminal 1 of the control output terminal block)
• PV event output/time event output (only when the program control option is specified)
• Program control end notification (only when the program control option is specified)
• Detection (Style Number S3 or Later)
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.
Setting the Alarm Delay (When [Type] is set to [T] or [t])
• First-CH/Last-CH
Select the target channels for setting the alarm delay. The target channels also apply
to [Tag], [TLOG], and [Rolling average] settings.
• Alarm delay
Set the alarm delay using an integer in the range of [1] to [3600] s.
Note
If the scan interval is 2 s and you set an odd value for the alarm delay period, it will operate at
the specified period + 1 s.
Example: If the alarm delay set to 5 s, the function will operate at 6 s.
