Item Description
DL-EP1 Error
Status
The error status of the DL-EP1 is output.
„
ON: An error occurred.
„ OFF: No error occurred.
Warning Status (Unassigned)
Error Status
The error status of the DL-EP1 or the error statuses of all the connected sensor
amplifiers are output.
When ON, a value is stored in "Error ID Number" and "Error Code". When OFF, 0
is stored in "Error ID Number" and "Error Code".
„
ON: An error occurred in the DL-EP1 or in any of the connected sensor
amplifiers.
„ OFF: No error occurred in the DL-EP1 or in the connected sensor amplifiers.
Sensor Error Status
The target ID number bit of the sensor amplifier where the error occurred is
output.
„
ON: An error occurred in the sensor amplifier with the target ID number.
„ OFF: No error occurred in the sensor amplifier with the target ID number.
Sensor Warning
Status
(Unassigned)
Current Value n
Over Range
(n: 0 to 1)
The current value n (n: 0 to 1) of the sensor amplifier with the target ID number
is compared with the measurement upper limit and the comparison result is
output.
„
ON: The current value n (n: 0 to 1) of the sensor amplifier with the target ID
number is greater than the measurement upper limit.
„ OFF: The current value n (n: 0 to 1) of the sensor amplifier with the target ID
number is less than the measurement upper limit.
(* The current value 1 does not exist in the GT2 Series.)
Current Value n
Under Range
(n: 0 to 1)
The current value n (n: 0 to 1) of the sensor amplifier with the target ID number
is compared with the measurement lower limit and the comparison result is
output.
„
ON: The current value of the sensor amplifier with the target ID number is less
than the measurement lower limit.
„ OFF: The current value of the sensor amplifier with the target ID number is
greater than the measurement lower limit.
(* The current value 1 does not exist in the GT2 Series.)
Current Value n
Invalid
(n: 0 to 1)
The status of current value n (n: 0 to 1) of the sensor amplifier with the target ID
number is output.
„
ON: The current value of the sensor amplifier with the target ID number is
invalid.
„ OFF: The current value of the sensor amplifier with the target ID number is
valid (normal).
(* The current value 1 does not exist in the GT2 Series.)
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: HH output
*1
Output 5: LL output *1
„ 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).

(Page 3-18).
