5.2ID Code for WAGO I/O System
Due to the combined use of digital, analog and special functions on one fieldbus station and with the given structure of the Interbus ID codes, it is impossible to manage with one ID code.
The WAGO Interbus S buscoupler is identified as a digital slave with variable length!

Table 3: ID codes for the WAGO Interbus S buscoupler
For the master, it is important to know how many data registers each user assigns in the Interbus S system. If a user has, for example, 16 bits of input and 32 bits of output, he assigns 2 words in the bus because there are 2 words of output. In this case the higher value of data width is decisive. The data width is coded by the bits ID 8 to ID 12 as shown in section 5.1.
The following table shows the register widths depending on the function modules connected to a WAGO Interbus S buscoupler.
Possible values for data length are::
