Switching output
Description
The value of the output process data is read in this mode. Signal changes are monitored.
The switching output mode is activated by means of the output process data. The actual
value of the relevant counter "Switching cycle number" is incremented by a predefined signal
change. The actual value of this counter is compared to the parameterized number of
switching cycles. If the actual switching cycle number reaches this value, the switching cycle
number status is set to "threshold reached". If the actual switching cycle number reaches 4
294 967 295 (0xFFFF
FFF [hex]), counting ceases and the status for the switching cycle
number is set to "expired". If the actual switching cycle number is lower than the number of
switching cycles and less than 4 294 967 295 (0xFFFFFFF [hex]), the status for the
switching cycle number is set to "active". When the switching output mode is deselected, the
status for the switching cycle number is set to "deactivated”. The actual switching cycle
number is stored in a buffer memory and is available as the start value for continued
counting when the switching output mode is selected again. When the device is switched off,
the actual switching cycle number is transferred to the non-volatile memory of the device so
that it can be retrieved when the device is next switched on. The actual switching cycle
number can be reset to zero by the following methods:
●
Change the number of switching cycles.
●
Switch over from the switching output mode to the switching input mode, and vice versa.
●
Change the type of counted edges.
●
Use the standard command "Restore Factory Setting".
●
Use the standard command “Application Reset”.
●
Use the standard command "Reset switching cycle counter at pin x" (x refers to the
number of the corresponding IO).
●
Use the standard command "Switching cycle counter at pins 1-8".
Parameters
●
Threshold switching cycle counter

Active edges
