Intelligent Gateway To Connect PLC Systems

UL Electrodevices offers a new Anybus gateway that enables a Profibus-DP Master to read and write J1939 network data for control and monitoring tasks. The gateway accomplishes this by operating simultaneously as a Profibus-DP Slave on a Profibus network and as a CAN node on a J1939 network. Data is exchanged from either network based on a user defined configuration. The company provides a free Windows-based configuration tool (BWConfig) that allows the user to map J1939 parameter (PGN) data into the module's input and output tables, accessible by the Profibus Master over the Profibus-DP network. With is rugged industrial design the device is designed for use across a wide variety of applications and industries. These include heavy duty equipment and vehicles used for agriculture, construction, fire and rescue, oil and gas, mining, power generation, motor control, material handling, trucking, mass-transportation and marine applications. Typical uses include applications in oil and gas production, or on-vehicle applications where the gateway is used as an interface between the J1939 network and Profibus based industrial PLCs. On the Profibus side the gateway supports Profibus-DP Slave functionality with cyclic I/O data transmission and it can handle up to 244 bytes input and 244 bytes of output data. On the J1939 side the gateway supports up to 35 incoming J1939 transport protocol (large message) sessions and can monitor up to 120 different PGNs in the input data point configuration and transmit up to 100 different PGNs in the output data point configuration. The J1939 transport protocol (large message) handler rejects incoming session requests (both BAM and RTS/CTS) for PGN/Address pairs that are not configured as input data points. The J1939 to Profibus gateway is the newest member of HMS´ Anybus gateway family, which consist of more than 180 individual versions providing inter-network communications between almost any fieldbus or industrial Ethernet network.
