CAN Specification

The SAE J1939 standard (Serial Control and Communications Heavy Duity Vehicle Network) has originally been designed by SAE International to be used in heavy duty vehicles. In the meantime, the protocol is widely used also in agricultural machinery, rail vehicles and sea vessels and in a wide range of diesel-driven machinery. Target group J1939 training The target group of the J1939 intensive workshop is development engineers who are looking for a quick start into handling the communications profile or would like to get an insight into the J1939 protocol stack. Also, we address decision makers and product managers to enable them to assess the suitability of the J1939 protocol stack for their applications.

The modul µCAN.4.ao-SNAP features 4 independent analogue outputs which optionally provide a voltage or a current signal. The CAN interface supports CANopen and J1939 protocols.Voltage +/- 10 VCurrent 0…20 mA Accuracy 0.05 % (FS) Resolution 16-bit (1 mV / 1 µA) Signal output 1 ms / 1 kHz Galvanically isolated fieldbus Galvanically isolated analogue outputs Signal type freely configurable Screw connection via plug-in connectors Protocol CANopen / Raw CAN / J1939

From the Idea to Prototyping to Series Production and Evolution – MicroControl plans, develops and manufactures individual solutions MicroControl has more than 26 years of experience in ICA, Bus communication and control technologies. From a variety of different projects we are well aware of the importance of communication and cooperation between all those involved in the project to realize the best solution in due time After a detailed list of technical specifications has been defined in close liaison with the customer, a development plan is created containing time lines and estimated costs. Also, a schedule for prototyping and manufacturing of the series product is established to meet the future lead times, which will give MicroControl customers maximum process reliability. If a non-conformity with the customer’s requirements or any other error is detected, MicroControl will re-design the product without additional costs for the customer to provide the best solution. In any case

CANopen has been developed by the members of the international user and producer assosiation CAN in Automation (CiA). The CANopen application layer defines different communication services and protocols (e.g. process and service data) as well as a network management. CANopen is mainly used as an embedded network in machinery, but also as a general industrial communications system. It is based on the international standards ISO 11898-1 (CAN protocol) and ISO 11898-2 (fast physical layer). The CANopen application layer has been standardized by the CENELEC and is defined in the European standard EN 50325-4.
