Datasheet

PSS9000
PSS9000 consist of a set of I/O cards for analog input, analog output, digital input and digital
output. There are also cards for counters and PID controllers. The cards are placed in a rack with the
bus QBUS, a bus originally designed for DEC's PDP-11 processor. The rack is connected via a PCI-
QBUS converter to an x86 PC, or connected via Ethernet, so called Remoterack.
The system is configured with objects from the SsabOx volume. There are objects representing the
Rack and Carde levels. The agent level i represented by the $Node object.
Rack objekt
Rack_SSAB
The Rack_SSAB object represents a 19” PSS9000 rack with QBUS backplane. The number of card
slots can vary.
The rack is connected to a x86 PC with a PCI-QBUS converter card, PCI-Q, that is installed into
the PC and connected to the rack with a cable. Several racks can be connected via bus extension
card.
The rackobjects are placed below the $Node objects and named C1, C2 etc (in older systems the
naming convention R1, R2 etc can be found).
Attributes
Rack_SSAB doesn't contain any attributes used by the system.
Driver
The PCI-QBUS converter, PCI-Q, requires installation of a driver.
Ssab_RemoteRack
The Ssab_RemoteRack object configures a PSS9000 rack connected via Ethernet. A BFBETH card
is inserted into the rack and connected Ethernet.
The object is placed below the $Node object and named E1, E2 etc.
