HI_OUT_D

Discrete output indicating state of Hi alarm condition.

INIT_STATUS

The initialization status of the block (used for debugging).

LAMBDA

The frequency response of a PID controller is dominated by the
Proportional, Integral, and Derivative modes in the three frequency regions
shown in the following figure. To limit excessive amplification at high
frequencies, a filter is used to create a “Derivative Limited” region. The
ratio of the derivative term to the filter time constant is defined as lambda.

LAST_BLOCK_EVENT

The last logged event detected by the block. Table C-7 lists descriptions of
the block events. This parameter is useful for debugging configuration
errors because it points to the parameter in error. For example, if an AI
block is in

OOS

mode because

L_TYPE

is not set, the

MGS

would say

Linearization Type Uninitialized
