FB_BA_FIFO04_XX

FB_BA_FIFO04_XX 1:

This function block is used to evaluate the FiFo memory from FB_BA_FIFO04. The inputs are linked according to the FIFO table to the corresponding outputs of the function block FB_BA_FIFO04_BOOL or FB_BA_FIFO04_REAL.

Sample:

In the sample the array contains: 4,3,1,2,0,0,0,0. The following result is output in FB_BA_FIFO04_REAL:

rIn01 at output rVal04

rIn02 at output rVal03

rIn03 at output rVal01

rIn04 at output rVal02

VAR_INPUT

arrFIFO          : Array [1..4] OF UDINT;
rIn01 - rIn04    : REAL;

aFIFO: Contains the assignment table with a maximum of eight values. The first value indicates where the first input was copied to, the second value where the second input was copied to and so on. No assignment takes place with "0".

rIn01 – rIn04: Setpoints to be linked.

VAR_OUTPUT

rVal01 - rVal04   : REAL;

rVal01 – rVal04: Actuator setpoint, input value linked according to FIFO table.
