# Add a Modbus Device
## Prerequisites
To successfully add your Modbus TCP devices into Motion, make sure:
* You've already activated a Motion Hub with which you want to associate your BACnet device
* The Motion Hub and the BACnet device are connected to the same local area network and the network is not blocking communication between the Motion Hub and the BACnet device
## Adding a Modbus TCP Device
Every Modbus TCP Device will need to be manually entered. Every Modbus TCP device requires an IP Address and a Slave ID, and in the steps below we will instruct users on how to do this.
### **Step 1**: Navigate to "Add Devices" view
