Modbus TCP/IP Client (Universal and Advanced Models)
The EcoStruxure Panel Server acts as both a Modbus TCP/IP gateway and a Modbus device by using the internal Modbus TCP server.
To correctly configure your Modbus TCP/IP client to access data from Panel Server and from devices under Panel Server, see Modbus Gateway Function.
The Panel Server acts as a Modbus gateway for wired or wireless Ethernet communications from an upstream PC to Ethernet devices and field devices on the downstream network. By using a local monitoring software you can access information from devices for data collection and other functions.
The Panel Server manages Modbus communication on all interfaces including Wi-Fi.
This function is available on Panel Server Universal and Advanced.
