In the motion data screen inputs DI1 to DI5 are only updated if DI6
shows a High level.
The active block can be calculated according to the following:
Active block = 8*DI4 + 4*DI3 + 2*DI2 + 1*DI1
where
DIx = 0 if input shows a Low level (0V)
DIx = 1 if input shows a High level (24V).
The following shows the relationships of the digital inputs in a truth table.

The blocks are activated by the high end controller (SPS / PLC) according to the table
shown using the digital inputs.
An overview of the connected signals to the controller and active block
can be found in the „Motion data" window described in the Section
