4.4.4 Configuration of Digital Modules
After the DP modules for the activated functions of the Bus Coupler and the complex terminals (KL15xx,
KL25xx, KL3xxx, KL4xxx, KL5xxx, KL6xxx, KL8xxx) have been added to the Bus Coupler in the DP
configuration tool in the sequence in which they are plugged in, the digital terminals follow. In the case of
digital terminals, it is only necessary for the total of the digital inputs and outputs of the modules that have
been added to agree with the number of digital inputs and outputs that are plugged in:
Sample
4 x KL1408 = 32 digital input bits
2 x KL2408 = 16 digital output bits
3 x KL1114 = 12 digital input bits
2 x KL2114 = 8 digital output bits
4 x KL1012 = 8 digital input bits
1 x KL2012 = 2 digital output bits
=> 52 digital input bits and 26 digital output bits
The following combinations of DP modules could, for instance, now be added in the DP configuration tool to
the Bus Coupler:
Alternative 1
8 digital input bits
8 digital input bits
8 digital input bits
8 digital input bits
8 digital input bits
8 digital input bits
8 digital input bits
8 digital output bits
8 digital output bits
8 digital output bits
8 digital output bits
Alternative 2
56 digital input bits
32 digital output bits
Other alternatives are possible, provided the total of digital inputs is 56 bits (the next number larger than 52
divisible by 8) and that the sum of the digital inputs is 32 bits (the next number larger than 26 divisible by 8).
4.4.5 GSD Files
GSD files are required for integrating the PROFIBUS couplers in DP configuration tools.
