Current Value 0/Current Value 1
Output n (n: 1 to 5)
The ON/OFF status of output n (n: 1 to 5) of the sensor amplifier with the target
ID number is output.
Output 1: HIGH output
Output 2: LOW output
Output 3: GO output
Output 4: Alarm output
Output 5: (Unassigned)
ON: Output n is output.
OFF: Output n is not output.
External Input
Response
n (n: 1 to 5)
An external input response is output when the corresponding external input
request n (n: 1 to 5) is made via communication.
The ID number of an unexisting external input is also output.
ON: The external input request was made (ON).
OFF: The external input request was not made (OFF).
For details, refer to
"Entering an external input to a sensor amplifier"
Error ID Number
If "Error Status" in ON, the ID number of the DL-EP1 where the error occurred and
the ID numbers of sensor amplifiers connected to the DL-EP1 are stored (the ID
number of the DL-EP1 is 0). If no error has occurred, 0 is stored. If an error occurs
in multiple IDs, the ID number of the DL-EP1 or sensor amplifier where the highest
priority error occurred is stored.
Error priority:
(1) DL-EP1 error
(2) Sensor amplifier errors (the error with the smallest error code has the
highest priority)
*
* If the same error code occurs in multiple sensor amplifiers, the error
with the smallest ID number has the highest priority.
Error Code
If "Error Status" is ON, the error code is stored. If no error has occurred, 0 is
stored. If an error occurs in multiple IDs, the error code of the DL-EP1 or sensor
amplifier where the highest priority error occurred is stored.
Error priority:
(1) DL-EP1 error
(2) Sensor amplifier errors (the error with the smallest error code has the
highest priority)
*
* If the same error code occurs in multiple sensor amplifiers, the error
with the smallest ID number has the highest priority.

Current Value n
(n: 0 to 1)
The current value n (n: 0 to 1) of the sensor amplifier is stored. The current value
0 always exists without reference to sensor amplifier models. Whether the
current value 1 exists depends on sensor amplifier models. If the current value
1 does not exist, 0 is stored. The contents displayed in the current value n (n: 0
to 1) depend on the use conditions.

(* The current value 1 does not exist in the IL Series.)
