The counter range:
Counter type
Explanation
16/32 bits up/down
counter
C0~C575 HC0~HC95 (32-bits counter occupies two registers, the
counter address must be even number)
High speed
counter
HSC0~HSC30 (HSC0,HSC2...HSC30) (each counter occupies two
registers, the counter address must be even number)
1: Please refer to chapter 5 for details of high speed counter.
2: XD/XL series counters can be 16 or 32 bits count up/down mode. The mode is appointed
by the instruction. Which means the same counter can be used as 16-bit or 32-bit. The
increment/subtraction counting mode is also specified by the instruction mode.

The soft component will appoint the type of counter: common counter or power-off retentive
counter.
The set value range of 16-bit count-up counter is K1~K32,767 (decimal). K0 and K1 have
the same function. They mean the counter output will act at the first counting.
If the PLC power supply is cut off, common counter value will be reset. The power-off
retentive counter value will be kept.
