FNC280 – HSCT / High Speed Counter Compare With Data Table
Outline
This instruction compares the current value of a high speed counter with a data table of comparison points, and then
sets or resets up to 16 output devices.
sets or resets up to 16 output devices.
1. Instruction format
2. Set data
3. Applicable devices
Only a high speed counter C235 to C255 can be specified in "S".
Explanation of function and operation
1. 32-bit operation (DHSCT)
The current value of a high speed counter specified in
is compared with the data table shown below which has
(3±m) points stored in
and later, and the operation output set value (ON or OFF) specified in the data table is
output
to
to +n-1.
