Logic Blocks

6.6.1 Description
The device offers four digital logic blocks that can be
configured as AND/NOR/OR/XOR. Each of these logic
blocks has 4 input signals. These input signals are
evaluated cyclically according to the cycle time.
The result of a logic block can be used as an input signal
for each other logic block. The configuration of Logic Block
Mode and the input signals can be set via the ISDU
parameter access.
Even though each logic block contains 4 inputs, a block
with fewer inputs can be used. The unused inputs are set
so that they cannot influence the result
6.6.2 Signal Inputs
All process data objects of the type Boolean can be used
for input configuration. The respective Object IDs can be
found in the respective section on the function.
6.6.3 Mode Inputs
The mode of a logic block can be set with the values from
Tab. 6-32.
