(Reference)
Input range Unit Remarks
712
Outtput port start number
at extension I/P unit slot 3
fixed assignment
Common -1 -1 ~ 599
300+(multiple of 8)
(Invalid when applicable slot DO not in use)
* Automatic assignment conducted from I/O Parameter No. 708
when the setting in I/O Parameter No. 708 is valid and also I/O
Parameter No. 710, 712 and 714 are set negative. (Applicable
only in DO used slots).
Invalid in negative value when in conditions other than above.
713
Intput port start number
at extension I/P unit slot 4
fixed assignment
Common -1 -1 ~ 299
000+(multiple of 8)
(Invalid when applicable slot DI not in use)
* Automatic assignment conducted from I/O Parameter No. 707
when the setting in I/O Parameter No. 707 is valid and also I/O
Parameter No. 709, 711 and 713 are set negative. (Applicable
only in DI used slots).
Invalid in negative value when in conditions other than above.
714
Outtput port start number
at extension I/P unit slot 4
fixed assignment
Common -1 -1 ~ 599
300+(multiple of 8)
(Invalid when applicable slot DO not in use)
* Automatic assignment conducted from I/O Parameter No. 708
when the setting in I/O Parameter No. 708 is valid and also I/O
Parameter No. 710, 712 and 714 are set negative. (Applicable
only in DO used slots).
Invalid in negative value when in conditions other than above.
715
Extension I/O unit error
monitor
Common 1 0 ~ 5
0: Unmonitored,
1: Monitor
2: Monitor (Not to monitor 24V I/O power related errors)
3: Monitor (Monitor only 24V I/O power related errors)
* There are some exceptions
* When the setting is established to 0 (= Not to monitor) or 2 (=
Monitor (Not to monitor 24V I/O power related errors)), the
system would not generate a system error in a 24V I/O power
related error. However, to protect the extension I/O unit, the
actual output of the digital I/O board will be shut in the circuit
afterwards.
716
Extension I/O unit
multi-channel DIO
external terminal block
overcurrent and power
supply error detection
input indication
Common 0H
0H ~
FFFFFFFFH
Bits 4 to 7: Extension I/O unit slot 2 input indication
Bits 8 to 11: Extension I/O unit slot 3 input indication
Bits 12 to 15: Extension I/O unit slot 4 input indication
(0: Not to input error detection
1: Error detection input = IN023 in card
2: Error detection input = card IN047
3: Error detection input = card IN 023/47)
* Establish the setting by checking the specifications of the
terminal block unit for multi-channel DIO to be connected.
* The input port used as an error detection input cannot be used
as a general-purposed input port.
