6-2-6
Timer/Counter Area
This area is used to manage the TIM, TIMH(15), TMHH(––), CNT, and
CNTR(12) instructions. The same numbers are used for timers and counters;
do not use the same number twice even for different instructions.
If TIM/CNT number is designated for word data, it will access the present
value (PV); if it is used for bit data, it will access the Completion Flag for the
timer/counter.
The Completion Flag turns ON when the PV of the timer/counter that is being
used goes to 0.
Interrupt processing is not performed for TIMH(15), i.e., timing processing is
performed only when the instructions is executed. If the cycle time is longer
than 10 ms, counting may not be reliable.
For details on using these instructions, refer to the individual explanations in
the
Customizable Counter Units Programming Manual
(W384).
6-2-7
DM Area
This area is used in word units. The DM Area is contained in I/O memory (i.e.,
areas that can be freely read and written from the ladder program) and areas
to which functions are allocated.
Read/Write Words in
DM Area
The words in this area do not have any special functions and can be used as
required in programming. They can be read and written to using instructions
or a Programming Device.
Other Parts of DM Area
Error Log Area
When a fatal or non-fatal error occurs in the Customizable Counter Unit, the
Special I/O Unit error code and the error contents are stored automatically in
this area along with the time and date at which the error occurred.
The contents of one record are shown below:
Error contents: If the Special I/O Unit error code is 0360 Hex, the Customiz-
able Counter Unit’s error code is stored in bits 00 to 07.
