CALL 112 – User LED
Control Purpose
Use CALL 112 to activate or de-activate the user LEDs (LED1 and LED2). Two
inputs arguments are required and no output arguments. The first input argument
activates or de-activates LED1. The second input argument activates or de-activates
LED2. An input argument of one activates the LED. An input argument of zero
deactivates the LED. Any other value has no effect on that particular LED.
Syntax
PUSH [LED1 state]
PUSH [LED2 state]
CALL 112
IMPORTANT
If port PRT1 is configured for DH485 protocol, this CALL has
no effect.
NOTE
When you change to Command mode, the user-defined LEDs
remain in their last state until you execute another CALL112.
