In pushbutton mode (bit 4 = 0) the automatic commands in automatic mode are latching, in
other words OpenAut and CloseAut can be reset to zero after changing the control. In manual
and local modes, however, the automatic commands are not saved and in the absence of
automatic commands the automatic control is tracked.
In switching mode (bit 4 = 1), control is selected with the OpenAut static signals. If input
OpenAut is not set the valve is closed. Control via CloseAut is not needed. If the "Activate
command reset for control" function (bit 3 = 1) is also activated, the OpenAut input is reset to
the neutral position after evaluation in the block.
Note
Switching mode can only be used for configuration with the auxiliary valve.
