High-speed Counter/Pulse Output Instructions
Section 3-21
Examples
■
Example 1
When CIO 000100 is ON in the following programming example, PRV2(883)
reads the present pulse frequency at high-speed counter 0, converts that
value to rotation speed (r/min), and outputs the hexadecimal result to D00201
and D00200.
■
Example 2
When CIO 000100 is ON in the following programming example, PRV2(883)
reads the counter PV, converts that value to number of revolutions, and out-
puts the hexadecimal result to D00301 and D00300.
3-21-4 REGISTER COMPARISON TABLE: CTBL(882) (CJ1M-CPU21/22/23
Only)
Purpose
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 CJ1M-CPU21/22/23 CPU Units only.
