}
17.3.28 _Wait
Syntax
_Wait( time )
Description
Waits for the period (in milliseconds (ms)) specified in a constant.
Key points
time
Constant that specifies the wait time in milliseconds; no variable possible.
Example
Timer_0 = 20000; // start value 20 s
while( Timer_0 ){} // wait 20 s
17.3.29 _WaitInput
Syntax
_WaitInput ( level, mask )
Description
The function waits until a specific level is present at specific input terminals. The re-
quired polarity of the input level and the relevant terminals are given as arguments. The
function waits until all input terminals marked with a one in mask have a "1" level or a
"0" level.
Key points
level
Constant expression that specifies which signal level the terminals should be
tested for. It can adopt one of the following values:
mask
Constant binary expression which specifies the terminals to be tested. The bits
in the expression have the following meaning
INFORMATION
If the waiting time is to be variable, you will have to initialize a timer (H487 ...H489)
instead of a WAIT command and program a loop until the timer has expired.
1: HIGH level ("1" level)
0: LOW level ("0" level)
