Serial device servers and gateways from Phoenix Contact give automation engineers an easy and cost-effective way to connect control systems and field devices. They support most common industrial protocols, with various combinations of HART, HART IP, Profinet, Modbus TCP, Modbus RTU, Raw/ASCII and EtherNet/IP. A serial device server connects serial-only devices (those with only an RS-232, RS-422 or RS-485 serial interface) to a local area network. A gateway converts the protocol of one device to the protocol suitable for interoperability with another device or tool. It is sometimes referred to as a protocol converter. Variants are available with one, two or four D-SUB 9 serial ports and one or two RJ45 Ethernet ports. Startup and configuration is simple using an embedded web server. To ensure secure communication, the devices include 256-bit AES encryption and optional authentication. 800/888-7388; www.phoenixcontact.com
