3.1.5.3 ID Code to the WAGO I/O System
On account of common use of digital, analog and special function at one
fieldbus station, the structure of the INTERBUS ID codes makes it necessary
to use more than one ID code.
The WAGO INTERBUS coupler reports in as a remote bus subscriber with a
variable length.
The ID code 0x3c is set when power is switched on. This code is then
overwritten by an ID code as given in the following table after importing the
module configuration:

It is essential for the master to "know" how many data registers each slave
occupies in the INTERBUS system. For example, if a slave has 16-bit inputs
and 32-bit outputs it occupies 2 words at the master. Here, the larger value is
significant. Coding of the data width is given by bits ID8 to ID12.
The following table shows the register widths as a function of the connected
I/O modules at the WAGO INTERBUS coupler. Possible data width values
are:
