Description

CAN-to-Ethernet gateway with integrated dia­gnostic functions
In addition to four galvanically isolated CAN channels, eSys-IDC4E1 provides an Ethernet con­nec­tion for data trans­mis­sion to a higher-level computer. For CAN bus mon­i­toring an active resistance meas­ure­ment is im­ple­men­ted, as well as an error frame de­tec­tion. With the help of this feature the module is able to take over the trou­ble­shoo­ting in a CAN network. eSys-IDC4E1 has its own logic, which detects error frames and counts them in an internal memory. Thus sporadic errors, such as the fal­si­fi­ca­tion of messages by a par­tic­i­pant in the network, can be detected.

Standardized SAE J2534 interface
The Sontheim Pass-Thru API is sup­plied as stan­dard inter­face with eSys-IDC4E1. Thus the module can be used for app­li­ca­tions based on J2534. Other higher level pro­tocols can be easily im­ple­men­ted on request.

 

Software architecture
The software architecture of the CAN module consists of a host device structure in which an x86 PC system as host uses the module as device to access the CAN bus. Ethernet is used for com­mu­ni­ca­tion between host and device. Com­mu­ni­cation is done via IP and a pro­prie­tary com­mu­ni­ca­tion pro­to­col based on UDP. For the i­dent­i­fi­cation (discover) of the CAN interfaces via LAN the procedure according to ISO 13400 is used. The firmware of the CAN module consists of a main thread, which processes the CAN communication and is also able to handle the transport layer of communication protocols (e. g. J1939-21/J1939-81, ISO 15765), as well as a dia­gnos­tic thread for self- and CAN dia­gno­sis. All services of the module that are not re­la­ted to direct CAN com­mu­ni­cation, such as con­fi­gu­ra­tion of bridging or CAN dia­gnos­tics, are handled via the so-called “toolbox” pro­to­col. The se­quen­ce of mes­sages received at the host inter­face cor­res­ponds to the sequence on the physical bus, regardless of whether the message was trans­mit­ted or received. This guarantees an extremely high-performance communication with low latency times.
