DI-5
The DI-5 counts pulses on the first four channels. Note: pulses can also be counted using any other digital
input (eg. DI-5 Chs 5-16, DI-1, IO-2, IO-3, IO-4) using ladder logic. Please see the topic Example - Counting
Pulses and Starts for more information.

5 #AIss.5 0-65535 R/W Digital Input 4 Total Pulses. Write to #AOss.5 to clear.
6 #AIss.6 0-65535 R/W Digital Input 1 Pulse Rate (Hz). Automatically cleared.
7 #AIss.7 0-65535 R/W Digital Input 2 Pulse Rate (Hz). Automatically cleared.

Hardware Overview
Examples
#DI3.5 Digital module in slot 3, digital input 5 status
#AI3.2 Digital module in slot 3, digital input 1 total pulses (read this address to obtain the total)
#AO3.2 Digital module in slot 3, digital input 1 total pulses (write to this address to clear the total)
#AI3.6 Digital module in slot 3, digital input 1 pulse rate
* If the maximum pulse rate is exceeded (>255 Hz), each byte will contain the lowest 8 bits of the actual pulse rate. Results are
unpredictable at pulse rates greater that 1 kHz.
