Programming
Programming in ADbasic
The module is comfortably programmed with
ADbasic
instructions. The
instructions are described in
ADbasic
online help and in the Pro II Software
manual.
The include file
ADwinPro_All.inc
contains instructions for the following
functions:
Pro II-CNT-T
Input / output level
TTL logic
Event input
TTL logic
Isolation
none
Pro II-CNT-D
Input / output level
compatible to RS422/485 (5V differ-
ential, 120
Ω
bus termiinating resis-
tor)
Event input
1 differential
(singleded operation possible)
Clock frequency SSI deccoder (CLK) 6kHz … 12.5MHz
Isolation
none
Pro II-CNT-I
Input current
typ.3.5mA / max. 7.5mA
input voltage range
(selectable via jumpers)
0…5V
0 … 12V
0…24V
reliable switching threshold
for 0
(low)
0…0.8V
0…1.6V
0…3.2V
reliable switching threshold
for 1
(high)
4.5…5V
10…12V
20…24V
Input over-voltage
8V
16V
30V
Negative voltage
-5V for all ranges
Switching time
100ns
Isolation
42V channel-channel / channel-GND
1. A low/high signal will reliably be recognized in the indicated voltage ranges. But the switch-
ing process can also be effected outside these voltage ranges.
