# Configure In-Sight vision system for Modbus TCP Communications

This topic describes how to connect an In-Sight vision system to a PLC using Modbus TCP communications.

## Establish Modbus TCP Communications

Before Modbus TCP communications can be established with an In-Sight vision system, the vision system must be configured to enable Modbus TCP Server, using the Industrial Ethernet utility of the vision system. Once enabled, the Modbus TCP Server Settings dialog is used to configure the connection to PLC.

1. Open In-Sight Vision Suite and select the vision system from the device list.
2. Open the Industrial Ethernet utility in the list of utilities.
3. In the Industrial Ethernet Configuration dialog, select Modbus TCP Server from the Select Protocol dropdown menu.
4. Configure the Max Connections and Idle Timeout controls.
5. Restart the In-Sight vision system to apply the changes, enabling the Modbus TCP Server service upon completion of the power cycle.
