High-speed Counters 1 and 2
Pulse signals from rotary encoders to ports 1 and 2 of the Pulse I/O Board
can be counted at high speed, and interrupt processing can be executed
according to the number of pulses counted. The two ports can be used inde-
pendently, and the counters used for ports 1 and 2 are high-speed counter 1
and high-speed counter 2.
This section describes how to use high-speed counters 1 and 2.
Note
The instructions that can be used are limited by the port mode setting of the
Board, which is set in the DM 6611 of the PC Setup.
