During the development, testing, and even mass-production operation of EVCC and SECC products, various compatibility problems may occur.
For example, charging may stop unexpectedly during the charging process, or the charging session may fail to start normally.
When these problems occur, many engineers find it difficult to locate the issue quickly and accurately due to limited debugging methods.
In some cases, it is even difficult to clearly determine the root cause of the problem, and engineers can only guess what may have happened on the other side of the communication link.
This is where a Sniffer becomes very useful.
A Sniffer can capture the original PLC data packets during the communication process.
After the packets are captured, engineers can analyze the data frames and quickly locate the problem.
The Sniffer is connected to a PC through an Ethernet cable.
The data packets can then be captured and analyzed using Wireshark.
This method is simple and practical, and it can greatly assist software engineers in troubleshooting and problem analysis.
For EVCC and SECC software engineers, a Sniffer is an essential debugging tool.
