Designation
This word stores a fixed code that is used to specify the area
when an address is specified as a parameter for a function block
instead of an input-output variable (VER_IN_OUT). This code is
used only by the OMRON FB Library. Do not change the contents
of this word.

A10100 A10100.00 Synchronous
Unit Operation
Servicing Flag
ON while synchronous unit operation is being performed.
ON: Synchronous unit operation being performed
OFF: Synchronous unit operation not being performed
Cleared Cleared Refreshed when the
synchronous signal
turns ON the sec-
ond time after
power is turned ON
or Unit is restarted.

Input Data
Refresh Error
Code
This word contains 0001 hex when the CPU Unit fails to receive
synchronous input data from a Synchronous Unit within the spec-
ified time.
0001 hex: Error
0000 hex: Normal
Cleared Cleared When synchronous
data is refreshed.
A10102 --- Synchronous
Operation Cycle
Time
This word contains the synchronous operation cycle time set in
the PLC Setup.
Retained Retained When power is
turned ON or the
Unit is restarted.

--- High-speed
Counter 0 Range
Comparison
Condition 1 to 32
In-range Flags
These flags indicate whether the PV is within any of the one to 32
ranges when high-speed counter 0 is being operated in range-
comparison mode with upper and lower limits. The In-range
Flags, however, will be ON whenever the comparison value is
within the range regardless of the whether the high-speed counter
is set to execute the interrupt task when the range is entered or
left.
OFF: Not in range, ON: In range
Bits 00 to 15 in the lower word correspond to ranges 1 to 16. Bits
00 to 15 in the upper word correspond to ranges 17 to 32.
