For a description, see section Reoccurring parameters (Page 144).
he parameter values at the "ParameterInput" input can be
triggered vis this input by a signal edge change.
A signal change at "EnterInput" is only taken into account when "Contin
u-
ousEnterFunct" = FALSE. If this condition is fulfilled, an edge change 0
→ 1
causes the parameter values entered in "ParameterInput" to be adopted and
transferred. There is no change check. The entire data area specified in "P
a-
rameterInput" is always transferred.
This method of triggering transfer is suitable for input vis hard
ware, for exam-
ple via a console or control panel. For further information and related param
e-
ters, refer to the section "Function" above.
If you do not require the parameter, simply leave it open.
The parameters that are read in are then transferred f 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 again 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 previously for the length of an OB1 cycle, no hardware input via
a command, setpoint or parameter block was detected.
The FB enters the detected 1-out-of-n error in the diagnostic buffer (event
ID B172). As long as the error remains, the error status is indicated via the
"InputError" output of FC Safe (see FC Safe, "InputError" parameter).
