DEADTIME

Description

Provides calculated output (PV) in which value changes may be delayed from the time that the corresponding change
occurred in the P1 input. The delay time can be fixed, or it can vary as the inverse of another input (P2).

Function

Applies a fixed or variable delay to a process input value

Inputs

Requires an input value (P1); a second input (P2) is optional.
P1 and P2 must be fetched from other function blocks

Outputs

Produces the following output:
PV and it’s status, PVSTS and PVSTSFL

Operators and
Functions

Table 3.A on page 3-4 lists the expression operators and functions supported by this block for reference.

Delay Table

Is used to accomplish the desired delays in the input (P1). P1 values are stored and shifted through the table at a rate
that is calculated to produce the desired Deadtime. The table-shift rate is derived from the following information:

•

The sample rate of the P1 value (TS). This is the execution rate of the function block.

•

The delay time (DELAYTIME). If fixed delay is selected, user specifies the delay; if variable delay is selected, the
delay is derived from P2.

•

The number of entries to use in the delay table (NUMLOC). The table has a maximum of 60 entries, but the user
may request to use fewer than that (by sorting to NUMLOC).

Delay Type

Two types of delay are supported:

•

Fixed Delay

•

Variable Delay
