Operating modes

Description Note
BIT
Marker bit shift operation

DW
Marker double word shift operation

The factory setting of this parameter is BIT.
The operating mode is determined by selecting different
function blocks:
SR - shift register (BIT) or
SR - shift register (DWORD)
and not with the parameters for the function block as is
usually the case.
If the BIT operating mode is selected, the inputs I1, I2
and outputs D1-D8 are displayed. They have no function
in BIT mode! If they are assigned operands, these will
have no effect. The wiring of the SR function block (BIT)
is carried out in the circuit diagram.
