CPU23 Only)
Purpose

Example 1
When CIO 000000 turns ON in the following programming example,
CTBL(882) registers a range comparison table for high-speed counter 0 and
starts comparison. When CIO 000001 turns ON, PRV(881) reads the range
comparison results at that time and stores them in CIO 0100.
000000
000001
Example 2
When CIO 000100 turns ON in the following programming example, PRV(881)
reads the frequency of the pulse being input to high-speed counter 0 at that
time and stores it as a hexadecimal value in D00200 and D00201.
000100
CTBL(882) is used to register a comparison table and perform comparisons
for a high-speed counter PV. Either target value or range comparisons are
possible. An interrupt task is executed when a specified condition is met.
This instruction is supported by the CJ1M-CPU22/CPU23 CPU Units only.
CTBL(882)
P
P: Port specifier
C
C: Control data
TB TB: First comparison table word
Operation
ON if the specified range for P or C is exceeded.
ON if the combination of P and C is not allowed.
ON if reading range comparison results is specified even
though range comparison is not being executed.
ON if reading the output frequency is specified for any-
thing except for high-speed counter 0.
ON if specified for a port not set for a high-speed counter.
ON if executed for a port not set for an interrupt input in
counter mode.
