Process Automation System Server
(PASS)
Note: If redundancy is required, a
secondary PASS is needed.
Single SE Station serves as PASS
and OWS in an independent
workstation.
Note: PanelView™ products require
PlantPAx 4.10 Library or earlier.
For smaller systems, one PASS-C
is required that
typically includes the following:
• FactoryTalk Directory server
•HMI server
•Data server
• Alarm and Event server
•EWS / OWS
The PASS-C supports functions
that would otherwise be hosted on
separate application servers. The
PASS-C single computer also
includes the following in a single
workstation:
• FactoryTalk Historian
• FactoryTalk AssetCentre
• Microsoft SQL Server
•FactoryTalk Batch
IMPORTANT: An additional PASS-C
is required for redundancy.
Note: Licensing per application is
separate from the PASS-C
template.
One PASS required that typically includes the following:
•HMI server
• Data server (Up to 2 Data services per PASS)
• Alarm and Event service
Note: Optional redundancy is available.
Note: Additional PASS Servers can be deployed to accommodate
additional data and alarm requirements. No additional FactoryTalk
licensing is required.
Engineering Workstation (EWS)
1 EWS required.
Provided separately
Included within PASS-C image
1 EWS required.

Operator Workstation OWS (Clients)
Provided separately via
independent workstation or thin
client.
FactoryTalk View SE Station license
can transition to FactoryTalk View
SE Client for DCS integration.
Note: PanelView™ products require

Max 10 OWS clients
Note: PASS-C requires additional
machines outside of PASS-C
image.
Can have as many as 120 OWS clients. AppServ-OWS as needed.
Controllers 1…5 Compact or ControlLogix 1…5 Compact or ControlLogix
ControlLogix Architecture
Actual count varies depending on application requirements. There’s
no hard limit to the number of controllers. The number of controllers
that can be supported per PASS (data server) depends on controller
selection, controller loading, and number of OWS.
Application Server - FactoryTalk
AssetCentre
Not applicable.
If attached to PlantPAx DCS,
confirm FactoryTalk AssetCentre
can access the skid's asset details.
Included within the PASS-C image

for the PlantPAx DCS.
Application servers
Not applicable. In chassis historian
and in controller batch capabilities
are available. Can be also
integrated with a distributed
architecture.
Included within the PASS-C image
