Hi Nick,

Hi Matthias,

is that using the 1996 IPAC-Profibus Interface that is listed in the

hardware support database on the EPICS web site?

no - it's a new driver which support the Softing PC 104 cards. Softing

is now producing also a Compact PCI card for us.

There's a special firmware available which supports redundant Profibus

connections and fail-over - in conjunction with the redundant IOC.

Configuring Profibus (DP - or PA) is quite complicated. You have to map

memory space of the I/O devices into the DPM on the IOC. So you need to

configure your records's addresses in a way that they match with the DMP

layout.

We have developed a configuration tool in CSS which creates an XML file.

(Like the Siemens 'Step 7' tool) This file is parsed on the IOC and

creates the memory layout in the DPM. The EPICS records get their

Profibus address from a reference in the configuration database. (When

the db files gets created)

We should finally write some documentation about it ;-))

Thanks
-Matthias
