Update Rate

 controls the rate at which process data is polled and process variables are

calculated. Update Rate = Special produces faster and “noisier” response to changes in the
process. Do not use Special mode unless required by your application.

For systems with a standard core processor, Special mode can improve performance for applications
with entrained air or Empty-Full-Empty conditions. This does not apply to systems with an enhanced
core processor.

Before setting Update Rate to Special:

•

Check the effects of Special mode on specific process variables.
