High-speed Counters 1 and 2

Operation Timing Example
Note The status of the AR Area flags shown above may differ from the actual pulse
output status due to the output frequency.
Port Mode Setting (ports 1 and 2)
0000 Hex: High-speed Counter Mode
0001 Hex: Simple Positioning Mode
Port 1 (Setting for pulse input.)
Fixed/Variable setting of pulse output duty factor
0 Hex: Use fixed duty factor pulse output (default).
1 Hex: Use variable duty factor pulse output.
Port 2 (Setting for pulse input.)
Fixed/Variable setting of pulse output duty factor
0 Hex: Use fixed duty factor pulse output (default).
1 Hex: Use variable duty factor pulse output.
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.
