B-13 Counter Area
The 256 counter numbers (C0000 to C0255) are shared by the CNT and CNTR(012) instructions. Counter
Completion Flags and present values (PVs) for these instructions are accessed with the counter numbers.
When a counter number is used in an operand that requires bit data, the counter number accesses the Com-
pletion Flag of the counter. When a counter number is used in an operand that requires word data, the counter
number accesses the PV of the counter.
Note It is not recommended to use the same counter number in two counter instructions because the
Counters are reset at the following times.
Counter Completion Flags can be force-set and force-reset.
Counter PVs cannot be force-set or force-reset, although the PVs can be refreshed indirectly by force-setting/
resetting the Completion Flag.
There are no restrictions in the order of using counter numbers or in the number of N.C. or N.O. conditions that
can be programmed. Counter PVs can be read as word data and used in programming.
Note When function blocks are being used, counter numbers C0206 to C0255 are part of the default FB
B-14 Data Memory (DM) Area
The DM Area is a multi-purpose data area that can be accessed in word-units only.
Coordinator Module words D00000 to D19999 are cleared to all zeros when the power supply is turned OFF
and ON again, but are held when the operating mode is changed from PROGRAM mode to RUN/MONITOR
mode or vice-versa.

Instruction
counters will not operate correctly if they are counting simultaneously. If two or more counter instructions
use the same counter number, an error will be generated during the program check, but the counters will
operate as long as the instructions are not executed in the same cycle.
Instance Area, so the CX-Programmer will automatically allocate these counters to variables used in the
function blocks if the default FB Instance Area settings are used.
When function blocks are being used, a compiling error will be generated if any of these counter num-
bers are used in the ladder program. If you want to use these counter numbers in the ladder program,
the default FB Instance Area settings can be changed in the CX-Programmer.
