High-speed Counter Board Section 2-1
DM 6611: 0001 (Sourcing outputs for external outputs 1 to 4, 8-digit BCD
for PV storage of high-speed counters 1 to 4)
DM 6643: 0003 (High-speed counter 1: Count frequency of 50 kHz; Linear
Mode; phase-Z signal + software reset; Up/Down Mode).
When the PV reaches 2500, IR 05000 will be turned ON and external output 1
will be turned ON.
When the PV reaches 7500, IR 05001 will be turned ON and external output 2
will be turned ON.
When the PV reaches 10000, IR 05002 will be turned ON and external output
3 will be turned ON.
