Network Interfaces

April 27, 2006
The cFP-1804 four-slot and cFP-1808 eight-slot Ethernet and serial-based Compact FieldPoint network interfaces can expand the I/O in any PC or programmable automation controller (PAC).

The interfaces offer five standard protocols for open connectivity with industrial platforms and allow for integration of more than 30 Compact FieldPoint industrial I/O modules. The cFP-1804 and cFP-1808 natively communicate with a variety of protocols running on RS-232 serial or Ethernet, including Modbus RTU, Modbus TCP, Modbus ASCII, Optomux, and the company's event-driven protocol. Users can choose modules including analog input and output, thermocouple, RTD, strain, high-current relay, and digital I/O. The platform has an extended operating temperature range, from 40 to 70°C. Using the LabView 8 graphical-programming environment, users can easily add Ethernet-based communication to PAC systems.
