24.5 FNC189 – HCMOV / High Speed Counter Move
Outline
This instruction updates the current value of a specified high speed counter or ring counter.
The function of this instruction varies depending on the PLC version.
1. Instruction format
2. Set data
3. Applicable devices
S: Only high speed counters (C235 to C255) and ring counters (D8099 and D8398)
*1
can be specified.
Explanation of function and operation
1. 32-bit operation (DHCMOV)
• The current value of a high speed counter or ring counter specified in is transferred to [ +1, ].
• After transfer, the current value of the high speed counter or ring counter is processed as shown in the table below
depending on the set value of "n":
*1. Ring counters (D8099 and D8398) cannot be specified in FX
3UC PLCs before Ver.2.20.
Operand Type Description Data Type
