Basic Characteristics RAPID

WaitDO Waits until a digital output signal is set
Example
Arguments
WaitDO (Wait Digital Output) is used to wait until a digital output is set.
WaitDO do4, 1;
Program Running
Program execution continues only after the do4 output has been set.
WaitDO grip_status, 0;
Program execution continues only after the grip_status output has been reset.
WaitDO Signal Value [\MaxTime] [\TimeFlag]
Signal Data type: signaldo
The name of the signal.
Value Data type: dionum
The desired value of the signal.
[\MaxTime] (Maximum Time) Data type: num
The maximum period of waiting time permitted, expressed in seconds. If this
time runs out before the condition is met, the error handler will be called, if there
is one, with the error code ERR_WAIT_MAXTIME. If there is no error handler,
the execution will be stopped.
[\TimeFlag] (Timeout Flag) Data type: bool
The output parameter that contains the value TRUE if the maximum permitted
waiting time runs out before the condition is met. If this parameter is included in
the instruction, it is not considered to be an error if the max. time runs out.
This argument is ignored if the MaxTime argument is not included in the instruction.
If the value of the signal is correct, when the instruction is executed, the program simply
continues with the following instruction.
