Inputs
In DW operating mode you assign function block inputs I1 and I2 with the
values that are to be read into the shift register. You can assign the following
operands to function block inputs:
•
Constant.
•
Markers MD, MW, MB.
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7.
•
IA02: Terminal I8.
•
IA03: Terminal I11.
•
IA04: Terminal I12.
•
Analog output QA01.
•
Output
…
QV of a different function block.
Outputs
Likewise, only in DW operating mode do the function block outputs D1 to D8
output register values 1 to 8. The outputs can have the following operands:
•
Analog output QA01.
•
Markers MD, MW, MB.
Function of the function block
The SR..EN coil is actuated.
You have set STOP mode
A rising edge at FP (ForwardPulse) causes the bit value to be accepted at
data input FD (ForwardData) into the first register field Q1. The original
contents of the register fields are then moved by one field in the direction of
the next higher field numbers.
