Not Just Modbus/TCP Connectivity to Serial and Ethernet TCP/IP Devices

Loaded with Modbus/TCP firmware, the DeviceMaster UP is the most innovative Modbus to raw/ASCII gateway available today.

The Modbus/TCP firmware has been designed to provide maximum functionality and flexibility with an emphasis on raw/ASCII device support. Its feature-rich platform also supports both slave and master serial Modbus devices.

While simultaneously supporting multiple Ethernet, Modbus/TCP and serial Modbus controllers, the Modbus/TCP firmware provides flexible connectivity to serial Modbus slave devices and both serial and Ethernet TCP/IP raw/ASCII devices. Not found in other gateways, the detailed diagnostic capabilities greatly simplify setup and improve maintenance capabilities. Whether you need to connect your PLC, SCADA system, HMI, or OPC Server to a raw/ASCII device, such as a barcode scanner, or a Modbus serial device such as a temperature sensor, the DeviceMaster UP will provide the solution.

Driven to provide additional connectivity options and advanced functionality for today’s most demanding Modbus environments, Comtrol continues to provide enhancements to the Modbus/TCP firmware.

Recent advancements include:

The DeviceMaster UP configures in just minutes via embedded web pages. The included PortVision DX remote management and configuration software makes it a simple task to detect and manage every DeviceMaster UP on the network, facilitating firmware updates, troubleshooting, and remote administration.
