■ Reading the Results of Range Comparison (C = 0002 hex)
If C is 0002 hex, PRV(881) reads the results of range comparison and stores it
in D as shown in the following diagram.

■ Reading Pulse Output or High-speed Counter Frequency (C = 00@3 hex)
If C is 00@3 hex, PRV(881) reads the frequency being output from pulse out-
put 0 to 3 or the frequency being input to high-speed counter 0 and stores it in
D and D+1.

Pulse Frequency Calculation Methods
There are two ways to calculate the frequency of pulses output from pulse
output 0 to 3 or pulses input to high-speed counter 0.
1. Standard Calculation Method (Earlier Method)

Comparison Result 1
OFF: Not in range ON: In range
Comparison Result 2
OFF: Not in range ON: In range
Comparison Result 3
OFF: Not in range ON: In range
Comparison Result 4
OFF: Not in range ON: In range
Comparison Result 5
OFF: Not in range ON: In range
Comparison Result 6
OFF: Not in range ON: In range
Comparison Result 7

method
0000 0000 to 0001 86A0 hex (0 to 100,000)
Note If a frequency higher than 100 kHz has
been input, the output will remain at the
maximum value of 0001 86A0 hex.
0000 0000 to 0003 0D40 hex (0 to 200,000)
Note If a frequency higher than 200 kHz has
been input, the output will remain at the
maximum value of 0003 0D40 hex.
0000 0000 to 000F 4240 hex (0 to 1,000,000)
Note If a frequency higher than 1 MHz has
been input, the output will remain at the
maximum value of 000F 4240 hex.
0000 0000 to 001E 8480 hex (0 to 2,000,000)
Note If a frequency higher than 2 MHz has
been input, the output will remain at the
maximum value of 001E 8480 hex.
