# 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
| Steps | Screenshots |

| Click "Add Devices" tab |  |
### **Step 2**: Navigate to "Add Device Manually" view
| Steps | Screenshots |
| --------------------------------------------------------------------------- | -------------------------------- |
| Click on the "Manual Entry" option, located inside of the Modbus TCP window |  |
### **Step 3**: Input Modbus TCP device details
You are now in the "Add Device Manually" view for a Modbus TCP device. You will now input the following information in the following sections:
1. Motion Hub
2. Name
3. Local IP Address
4. Protocol
5. Modbus Slave ID
6. Save/Revert
