Example: Shift register DW mode, backward
Figure 183:Shift register SR..: Backwards operation in DW operating mode
a
Initial situation:
– SR..EN is not activated, the function block is not active.
– SR..D2 contains the value 8, a 0 is contained in the other register fields.
b
Transfer of value:
– SR..EN is activated, the function block is active.
– SR..I2 has the value 10.
– With the backwards pulse from SR..BP the register field SR..D8 shifts the content of all register fields
one place back and accepts the 10 from SR..I2.
c
Transfer of value:
– SR..EN is activated, the function block is active.
– SR..I2 has the value 52.
– With the backwards pulse from SR..BP the register field SR..D8 shifts the content of all register fields
one place back and accepts the 52 from SR..I2.
d
Reset of the register:
– SR..EN is activated, the function block is active.
– Activating SR..RE clears the content of the register.
Application example
Different workpieces are moved along a production line with several
machining stations. An operator determines the work required for the
individual workpieces, creates a production code for it and writes it into a
shift register.
