ATTENTION
ON/OFF loop types provides direct output without the use of an analog output. To complete an ON/OFF loop
configuration, assign the ON/OFF loop's output (LPn OS) to a Discrete Output Relay (see Program Discrete
Outputs, section 4.11).

Definition
Positioning Algorithm – Specify the appropriate algorithm.
The rules are:
• AUTO and DIAT algorithm can be used only with DIAT loop
type.
• PP algorithm can be used only with loop types other than
DIAT.
• PP and AUTO algorithms require a feedback analog input.
AUTO permits normal feedback positioning of the drive motor
when the feedback input is good, and defaults to DIAT
operation if the slidewire feedback input fails.
This is the increasing discrete output channel for the
POS_PROP or DIAT positioning algorithms.
This is the decreasing discrete output channel for the
POS_PROP or DIAT positioning algorithms.
