How to use these pins as digital outputs (Pin 4, 5, 6)
The FOX device supports three IOs which can be used either as input or output.
These outputs are open collectors. They can be directly connected via resistors (R) to
LEDs, Relays etc., which need no more than
100 mA @ up to + 35.0 V DC. The figures
below show the schematic of possible output connections. To use and
activate these
outputs use the command
$PFAL,IO4
[5,6]
.Set=high
[low,hpulse,lpulse,cyclic]
for
IO1, IO2
and
IO3
respectively or you can configure an or more alarms that activate these
outputs when specific events occur (e.g.
PFAL,Cnf.Set,AL0=IO.e8=redge:IO4.Set=cyclic,
1000,2000
).
In order to evaluate this alarm, firstly send this configuration to the FOX
device and then trigger IGN-pin to High – as result the IO1 goes High for 1 sec and Low
for 2 sec. To set IO1 to Low, just execute the command
PFAL,IO4.Set=Low.
For more
details how to activate an output and how to configure an alarm, refer to the
manual “
steppIII_fox_bolero_lt_PFAL_Configuration_Command_Set.pdf
“. Both
figures below show the schematic
connections of how to use this output.
Please note
that, no power should be applied directly to an output pin without having e.g. a
resistor between output pin and power source.
