WAITI
The WAITI command waits before continuing the
processing until the specified input has got the
desired signal level.
Summary
Wait for defined input condition
Syntax
WAITI n s
Parameter
n = input number
1 – 8 or 16 – 33
s = expected condition:
ON = High-Signal
OFF = Low-Signal
NB!
If the expected input condition does not occur,
then the program will remain ‘stuck’ at this
point. A minimal signal length is required for the
sure identification of a signal condition!
The VLT manual and the chapter input/output
terminals give information about the circuit and
technical data for the inputs.
