10.16.2 General parameters - Working mode of the buttons
Options:
Button value 1, 2nd button value 2
Button value 2, 2nd button value 1
Alternating value1/value2
The parameter "Working mode of the buttons" is used to specify whether the 1st button or 2nd
button sends out "Value 1" or "Value 2". With the behaviour "Alternating Value1/Value2",
switching is always between Value 1 and Value 2. That means, for example, if value 1 was last
sent out, then a renewed operation of the button will send out value 2. When the button is
operated again, value 1 is again sent out, etc. The button thus always remembers the last state
and then switches over to the other value.
This also applies for values that are received via the associated communication object, i.e. if
value 1 was sent out for the last button operation, thereafter value 2 was received via the
communication object, the next operation of the button will send out value 1 again. It must be
observed here that the S-flag (writing) of the communication object is activated.
