– Bus coupler
The total length of the output data in the example configuration is 11 bytes. Of this, 10 bytes are the
module output data and 1 byte is the bus coupler parameter byte.
The total length of the input data in the example configuration is 12 bytes. This consists of 4 bytes of
module input data and 8 bytes of module diagnostic data.
The valve system always sends and receives the input and output data bytes in the same physical
sequence. This cannot be changed. In most masters, however, alias names can be assigned to the
data, making it possible for users to select any desired names for the data.
