4.4.4 Relay and LED Outputs
Sets the state of a relay.
The relay is driven by PA0, which is the same Rabbit 2000 parallel port that drives OUT0 and LED DS4.
OUT0 therefore works in parallel with the relay output. Z-World therefore recommends that you do not
use OUT0 for a digital output when you are using the relay.
PARAMETERS
relay is the relay to control, 0 = Relay 0.
value is the value used to connect the relay common contact to one of the following contacts:
0 = relay common connected to relay normally closed contact
1 = relay common connected to relay normally open contact
