Function
This word contains the system timer used after the
power is turned ON.
0000 hex is set when the power is turned ON and
this value is automatically incremented by 1 every
10 ms. The value returns to 0000 hex after reaching
FFFF hex (655,350 ms), and then continues to be
automatically incremented by 1 every 10 ms.
Note: The timer will continue to be incremented
when the operating mode is switched to RUN
mode.
Example: The interval can be counted between pro-
cessing A and processing B without requir-
ing timer instructions. This is achieved by
calculating the difference between the
value in A000 for processing A and the
value in A000 for processing B. The inter-
val is counted in 10 ms units.

A bit will turn ON to indicate when the load short-cir-
cuit protection function alarm output has been given.
Only the 4 most LSB are used for the CJ1W-OD202
(2 points per bit), only the LSB is used for the CJ1W-
OD212, OD204, MD232 and only the two most LSB
are used for the CJ1W-OD232. Each bit indicates the
status for one circuit.
1: Short circuited
0: Normal
