Comparison Table Target-value Comparison Table
Depending on the number of target values in the table, the target-value com-
parison table requires a continuous block of 4 to 145 words.
Range Comparison Table
The range comparison table requires a continuous block of 40 words because
comparison conditions 1 to 8 require 5 words each (2 words for the upper
range value, 2 words for the lower range value, and one word for the interrupt
task number).
Note Always set the upper limit greater than or equal to the lower limit in each
range.
MODE CONTROL
Instruction: INI(880)
INI(880) can be used to start/stop comparison with the high-speed counter’s
comparison table, change the high-speed counter’s PV, change the PV of
interrupt inputs in counter mode, and control the pulse output functions.
