PFC200 line of four controllers combines dual Ethernet ports with multiple fieldbus interfaces, enabling the controllers to serve as fieldbus gateways while communicating with other control systems. Users change between integrated ports to switch a field device between CANopen, Profibus or Serial RS-232/RS-485 within one unit with no third-party converters. The devices have a 600-MHz ARM Cortex-A8 processor, and compatibility with DHCP, DNS, SNTP, FTP, TELENET and HTTP protocols enables the units to interface with standard PLC applications and additional control systems.
