The "1-button value transmitter" application makes its own "Value switching"
communication object available for the button. The bit size of the communication object
is specified via the "Object type" parameter.
For the most diverse applications, the bit size of the communication objects can be
adapted from "1-bit" up to "4-byte unsigned" via "Object type". For every multiple
operation function, a different object size and thus a different function can be select.
– 1 bit: switching functions (e.g. On/Off, enable/blocked, true/untrue)
– 1 byte 0 - 100%: percentage values (0 = 0%, 255 = 100%)
– 1 byte 0 - 255: arbitrary values from 0 to 255
– 2-byte float: floating point value (physical values such as temperature or brightness) -
671088.64 to 671088.64
– 2-byte signed: arbitrary values from -32768 to +32767
– 2-byte unsigned: arbitrary values from 0 to 65,535
– 4-byte float: floating point value (physical values) -4000000 to 4000000
– 4-byte signed: arbitrary values from -2147483648 to 2147483647
– 4-byte unsigned: arbitrary values from 0 to 4294967295
12.10.2 Extended parameter – Reaction on rising edge
Options
The application can differentiate between the operation and the releasing of the button.
An operation is designate as "Rising edge" and the releasing is designate as "Falling
edge". The application "1-button value transmitter" makes two separate "Switching"
communication objects available for the left or right side of the button. The value 1 is
always sent out on the first object (Value 1) and the value 2 is always sent out on the
second object (Value 2)
The "Reaction to rising edge" parameter specifies whether the "Value 1 for rising edge"
or the "Value 2 for rising edge" is sent out for rising edge. Alternatively, Value1/Value2
can also be alternatingly set for a rising edge, i.e. after Value 1 was sent (or received), a
renewed operation will send out Value 2. After it is operated again, Value 1 is again sent
out. The values 1 and 2 are specified via the parameters "Value 1" and "Value 2".
The "No reaction" setting causes no telegram to be sent out for an operation of the button.
