Shift register (0BA7 to 0BA8)
Short description
The shift register function reads an input value and shifts the bits. The output value
corresponds with the configured shift register bit. The shift direction can be changed at a
special input.
For LOGO! 0BA6, you can use only one shift register in one circuit program, but for LOGO!
For LOGO! 0BA6, you can use only one shift register in one circuit program, but for LOGO!
0BA7 and LOGO! 0BA8 devices, you can use a maximum of four shift registers with eight
bits for each shift register in one circuit program.
Connection
Description
Input In
The function when started reads this input value.
Input Trg
The SFB is started with a positive edge (0 to 1 transition) at input Trg (Trigger). A 1
to 0 transition is irrelevant.
Input Dir
You define the shift direction of the shift register bits Sx.1 to Sx.8 at the Dir input:
Dir = 0: shift up (Sx.1 >> Sx.8)
Dir = 1: shift down (Sx.8 >> Sx.1)
NOTE:
"x" refers to the index of the shift register.
NOTE:
"x" refers to the index of the shift register.
Parameter
Shift register index: the index of shift register in the circuit program.
Possible settings: 1 to 4
Shift register bit that determines the value of output Q.
Possible settings: 1 to 4

Retentivity set (on) = the status is retentive in memory.
Retentivity set (on) = the status is retentive in memory.
Output Q
The output value corresponds with the configured shift register bit.
