The Profibus-DP interface is optional, and must therefore be expressly requested when ordering the
EC-4 board.
The Profibus interface implemented is based on the ASIC LSPM2. The EC-4 is seen by the profibus
master as a remote I/O module with 16 inputs and 16 outputs. Obviously, the I/Os are virtual.
Interpretation of the meaning of the I/Os will be defined by the program installed on the EC-4
board.
The configuration file SBC0EC4.GSD is provided to configure the EC-4 as a slave Profibus-DP.
