The Signal Routing Block lets you redirect signals from the IO Block, the Video IO Block, Lookup Table,
and the Enhanced Function Block back into the Lookup Table for further processing. Because most of the
other blocks in the PLC use preconfigured inputs and outputs, the Signal Routing Block is the primary
method of routing a signal from one block to another.
How the Signal Routing Block Works
The Signal Routing Block has 8 outputs (I0 - I7). Each output uses a 16:1 multiplexer that connects to
16 inputs.
The Signal Routing Block has more than 16 input signals, so not every input can be connected to every one of
signals I0 - I7. However, signals I0 - I7 are functionally identical, so connecting to a specific one isn’t important. If
you can’t route the input with your first choice, simply choose another.
The Lookup Table lets you connect any input signal I0-I7 to any Lookup Table output signal Q0-Q17
