I/O module verify
error
Bit pattern in units of 16
points of verify error
units
• When I/O modules, of which data are different from those
entered at power-on, have been detected, the I/O unit
numbers (in units of 16 points) are entered in bit pattern.
(Preset I/O unit numbers when parameter setting has
been performed.)

• I/O module verify check is executed also to remote I/O
station modules.
(If normal status is restored, clear is not performed.
Therefore, it is required to perform clear by user
program.)
Usable with all
types of CPUs
Only remote
I/O station
information is
valid for A2C.

I/O module
verification error
Bit pattern of
verification error
module
• When an I/O module different from the I/O module data
registered during power-on is detected, this register
indicates the bit pattern of the I/O module number.

Annunciator
detection quantity
Annunciator detection
quantity
• When one of F0 to 255 (F0 to 2047 for AnA and AnU) is
turned on by SET F 1 is added to the contents of
D9124. When RST F or LEDR instruction is executed,
1 is subtracted from the contents of D9124. (If the
INDICATOR RESET switch is provided to the CPU,
pressing the switch can execute the same processing.)
• Quantity, which has been turned on by SET F is stored
into D9124 in BIN code. The quantity turned on with
SET F is stored up to “8.”
Usable with all
types of CPUs.
