Description
• When I/O modules, of which data are different from
those entered at power-on, have been detected, the I/
O module numbers (in units of 16 points) are entered in
bit pattern. (Preset I/O module 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.)
• 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.

• 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.

detection quantity 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."
