– Signals at step start and end (only available for Gauging)
It is possible to set and reset digital outputs directly from the tightening program. At cycle start all the
signals will be cleared, i.e. set low. If a signal is already high and are supposed to be set high from a step,
nothing at all will happen, and vice versa if it is already low. A signal used for step start or step end is not
allowed to be used in the zones in the same step.
Digital signal at step start:
Output signal
specifies the signal to use. With the combobox Change at it is possible to select if the
signal shall be set directly at step start or when a specific angle has been reached. If the signal shall be
set high or low is specified with the combobox
Value.
Digital signal at step end:
The signal to use is specified with the combobox Output signal . The signal is set to the selected Value
(high or low) when the step ends.
For both step start and step end the following digital signals are avaliable:
Local DO 1, … Local DO 4
(the digital outputs directly on the TC)
PLC_DI_1, … PLC_DI_10
(avalible as inputs in the PLC)
