1.1. General Information
The VME-PROF-S is a compete
independent PROFIBUS-DP-Slave
interface on an VMEbus board. The
interface is based on the SPC3-ASIC
which handles the layer 1 / 2 of the
PROFIBUS protocol (DIN 19245 / EN
50170) and the MC68331 processor.
64 kB dualport-RAM are used as data
interface to the VMEbus.
With the PROFIBUS-DP-Slave
firmware (DPS), the VME-PROF-S
builds a independent arbitrary
configurable DP-Slave interface. The
slave is configured through the dual-
port-RAM. The configuration can be
build with max. 32 configuration bytes
and can use up to 244 input bytes and
244 output bytes. The total amount of
input / output data can be 400 bytes.
Due to the arbitrary configuration the
Slave can fit the requirements of the
VMEbus system or the VME-PROF-S
can be used to simulate other Slaves.
