# Modbus Effect

Spikemark has the ability to connect to external, third-party devices using Modbus TCP/IP protocols. Similar to a Stagehand FX, the Modbus Effect allows you to select a specific Modbus coil to be ACTIVATED or CLEARED that could control any number of other effects.

Click on Stagehand, and select Add Modbus Effect.
