Instructions
Instruction
(@)CTBL(63) Used to register target or range comparison tables or to start comparisons for previously registered
comparison tables.
(@)INI(61) Used to start or stop comparison using registered comparison table or to change the PV of a high-
speed counter.
(@)PRV(62) Used to read the PV or status of a high-speed counter.
(@)INT(89) Used to perform mask all interrupts, such as input interrupts, interval timer interrupts, and high-speed
counter interrupts.

Flag
Function
Lit when input bit 0 is ON.
Lit when value input is incremented.
Lit when value input is decremented.
Meaning
Function
port 1 of the Absolute Encoder Interface Board is stored
as an 8-digit BCD after each cycle.
---
Function
When using high-speed counter 1 in
range comparison mode, each bit
turns ON when the corresponding
condition is satisfied.
