There are several types of nodes available using iFIX.
Types of Nodes

Description
|
|
Local and Remote
|
When working with a distributed iFIX system, local
refers to the node on which you are currently working and remote refers
to any node that you need a communication link to access.
|
|
Stand Alone
|
When working with a centralized iFIX SCADA system,
stand alone refers to a node that performs all functions. Stand alone
nodes do not use a network.
|
|
SCADA Server
|
A SCADA Server (or SCADA node) runs the data acquisition
and management component of iFIX. Usually, a SCADA node resides on the
plant floor and has direct connections to the process hardware.
|
|
Blind SCADA Server
|
A blind SCADA Server (or blind SCADA node) uses no
graphics display. This configuration frees up more of a computer's resources
for data acquisition and network management functions. Graphics can be
viewed using an iClient.
|
|
Run-time
|
A run-time node does not let you modify graphic displays
or the process database. Pre-configured files are installed on these nodes
so that you can monitor the process, change process settings, and acknowledge
alarms.
|
|
iClient
|
An iClient (or view node) is the most common type
of node. View nodes display the real-time graphics that come with iFIX.
The term view node means that the node runs the graphics display program,
but the node can run other applications, as well.
|
|
iClient Read Only
|
The iClient Read Only has the same functionality as
an iClient, except that you cannot write to the iFIX database or to OPC
servers. You also cannot construct SQL Insert or Update commands in an
iClient Read Only node. You can, however, write to a relational database.
The iClient Read Only is similar in functionality to PlantTV®
for FIX, with the added benefit of leveraging the iClient features, such
as the event scheduler, VBA, and ActiveX controls.
