HMS Industrial Networks gateway connects SAE J1939 networks to Siemens PLCs
Oil and gas production and on-vehicle applications will benefit from an HMS Industrial Networks Anybus intelligent gateway. It enables a Profibus-DP Master to read and write J1939 network data for control and monitoring. See also ControlNet announcement.

HMS Anybus-CC – Embedded ControlNet SlaveInterface (board, connectors, and case) and Anybus-S EmbeddedControlNet Slave Interface (just board and connectors) are less thanhalf the size and about half the price as prior offerings, according toTrevor Lang, HMS business development manager, at Automation Fair , theRockwell Automation conference and tradeshow in Anaheim, CA, Nov. 11and 12. See other Automation Fair announcements .
Langexplained to Control Engineering that Anybus-CC – Embedded ControlNetSlave are cost optimized plug-in modules built on Anybus NP30 ASICtechnology with parallel and serial interfaces. They are powered by thenew Anybus NP30 ASIC. The Anybus-S Embedded ControlNet Slave Interfaceis a high performance adapter interface card designed for OEMintegration. It has a Network Access Port (NAP), and 2kB DPRAM parallelinterface. It is interchangeable and credit-card sized.
A new Anybus intelligent gateway enables a Profibus-DP Master to read and write J1939 network data for control and monitoring tasks. The gateway operates 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.
HMS provides a free Microsoft 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 a 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 & 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, HMS says. On the J1939 side the gateway supports up to 35 incoming J1939 transport protocol (large message) sessions and can monitor up to 120 PGNs in the input data point configuration and transmit up to 100 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 HMS Anybus gateway family consists of more than 180 individual versions providing inter-network communications between almost any fieldbus or industrial Ethernet network.
