Controllers
Experion supports a wide range of controllers in addition to Process Controllers. This chapter
describes issues you need to consider in order to integrate these controllers with your
Experion system. (The Control Hardware Planning Guide contains planning information for
Process Controllers.)

Scanning strategies
Interface references
There is a separate interface reference for each type of SCADA controller supported by
Experion. These references include integration details, such as connection and configuration
options, that may affect your design and planning decisions.
If Quick Builder is used to configure a controller, the interface reference is also included in
Quick Builder's help.
Monitoring and control strategies
Attention:
Do not include the server in any control loops because potential delays, caused by
communications traffic or heavy server loads, may seriously affect your plant's
operation.
You should configure controllers so that they do not impose excessive communications or
processing loads on the server. It is important to remember that the server's primary tasks are
to:
Monitor system activity

Start/stop processes

Comments
Read the interface reference for each type of controller you want to
integrate with Experion.
Configure the controllers so that they do not impose excessive
communications or processing loads on the server.
Determine the server's data update requirements, and then design a scanning
strategy that minimizes the communications load.
