Multi Port Switch

This function block routes one of many incoming values to its output based on a reference selector. Use it when you want to pick a single input stream (or value) from a configurable list at runtime.

📥 Inputs

Switch Accepts a selector value. This can be:

• a single number (selects the input at that index), or

• a boolean/list of booleans (selects the first input where the value is TRUE).

Input 0, Input 1, ... Additional generic inputs. The number of available inputs is adjustable via the block controls.

(Each of the above are input sockets on the block.)

📤 Outputs

Generic The output forwards the data coming from the selected input socket.

(This is the output socket on the block.)

🕹️ Controls

Number of inputs A dropdown that lets you choose how many input sockets the block exposes (more inputs appear or are removed accordingly).

(Use this control to adapt the block to your scenario — from a few inputs up to the configured maximum.)

⚙️ Running mechanism

• The block reads the value provided to Switch and determines which input to route.

• If Switch is a number, the block routes the input at that numeric index.

• If Switch is a boolean list, the block finds the first TRUE entry and routes the corresponding input.

• If the selected input is not connected or empty, the block reports an invalid selection and does not forward a value.

This behavior makes the block suitable for runtime decision-making and conditional routing in visual flows.

✨ Features

• Dynamic input count: Add or remove inputs from the UI without redesigning the flow.

• Accepts numeric or boolean selectors for flexible control.

• Generic input/output sockets: works with images, numbers, text, lists, or other data types.

📝 Usage Instructions

1. Set the desired number of inputs with Number of inputs.

2. Provide values to the corresponding Input X sockets.

3. Drive the Switch socket with a numeric selector (use Number Input) or a boolean/list selector (use Logic Input or other logic-producing blocks).

4. Read the routed value from the Generic output.

💡 Tips and Tricks

• Use Number Input to manually choose an input index during testing.

• Use Logic Input or logical operators such as And / Or to generate boolean selectors for the Switch socket.

• Combine with Mux or Demux when converting between grouped/listed data and individual sockets. For example, gather values into a list with Demux then use a boolean list to select one with this block.

• Use Data Memory to hold a selected value and feed it back as a stable input to the block.

• Place this block before Show Image to switch which image source is displayed, or before an analysis block like Find Object to test different image inputs quickly.

• In automation flows, combine with Subsystem Enabled or Set - Reset to switch sources depending on system state.

(hint: recommended companion blocks include Number Input, Logic Input, Mux, Demux, Data Memory, Show Image, and Find Object.)

🛠️ Troubleshooting

• If nothing appears on the output, check that the selected input socket is connected and that Switch points to the correct index or TRUE entry.

• If selection jumps unexpectedly, verify the source driving Switch (it may be changing each cycle). Use Data Memory to stabilize the selector if needed.

• If you need more inputs than currently available, increase the count with Number of inputs and reconnect your sources.
