FB_BA_FIFO08_XX

FB_BA_FIFO08_XX 1:

The function block FB_BA_FIFO08_XX is used to evaluate the FiFo memory from FB_BA_FIFO08. The inputs are linked according to the FIFO table to the corresponding outputs of the function block FB_BA_FIFO08_BOOL or FB_BA_FIFO08_REAL.

Example:

In the sample the array contains: 4,3,1,2,0,0,0,0. The following result is output in FB_BA_FIFO08_REAL:

fIn01 on output fVal04

fIn02 on output fVal03

fIn03 on output fVal01

fIn04 on output fVal02

FB_BA_FIFO08_XX 2: Inputs

VAR_INPUT
  aFIFO          : Array [1..8] OF UDINT;
  fIn01…fIn08    : REAL;
END_VAR

Name

Type

Description

aFIFO

ARRAY OF UDINT
