Interface blocks
Various interface blocks for the IP Core allow simpler access for differing drive architec‐
tures. SICK provides two different interface blocks as open-source VHDL modules. This
enables individual modifications and adaptations. There are examples for a parallel or
serial interface.
This section describes the connections between the interface blocks and the IP Core.
CAUTION
If interface blocks are altered or self-created, the installer must pay attention to the
safety measures and processes when doing so. It is recommended that the interface
blocks for Safe 1 and Safe 2 interface should be realized by using the SPI interface.
The figure below shows possible combinations of interface blocks.
