Here is a quick look on two of the systems, yes there is a PCI card. I am not sure if I can post links here , sorry about that.
PCI card :
Motion controller:
Servo drives :
They are all based around the Logosol Distributed Control Network (LDCN) running on RS-485. Well build devices that have run many years. We want to migrate the software to MACH though as the original one has some restrictions. I believe that with the proper plugin this should not be a problem.
