The transmission of the parameter value at ParameterInput can be triggered
over this input by a signal edge change.
A signal change at EnterInput is only taken into account when the parameter
ContinuousEnterFunct = FALSE. If this condition is fulfilled, a transition from
0 to 1 causes the parameter values specified at ParameterInput to be
entered and transmitted. Changes are not checked. The entire data area
specified by ParameterInput is always transmitted.
This method of transmission triggering is suitable for input with appropriate
hardware, for example at a console or control panel. For more detailed
information and related parameters, refer to the section Function.
If you do not require the parameter, simply leave it open.
Data checks:
• The parameters that are read in are then transmitted if no error is
detected during the 1-out-of-n check, and if the central enable memory bit
is set. This is automatically set by FC Safe following a selected time
delay set there (see FC Safe, InputDelayTime parameter). The input area
is then only read in by the FB when a 0 signal was detected at EnterInput
for at least one OB1 cycle.
• When a 1-out-of-n error is detected at the "hardware" input, the entered
parameters are no longer processed. New parameters are read in again
only when no "hardware" input has been acquired in the PLC for one
OB1 cycle; in other words, not only for this block but also for all other
command, setpoint and parameter blocks with "hardware" input. The FB
enters the detected 1-out-of-n error in the diagnostic buffer (event ID
B172). The error status is also indicated over the InputError output of FC
Safe (see FC Safe, InputError parameter) and continues to be indicated
as long as the error remains.
