B.6.10 TRACES AND TROUBLESHOOTING
The tracer is a debugging tool to view the strings in any writing or reading process in ModBus. This tracer is activated in the
menu from W650: View, Traces.
With this option enabled, request and response strings will be shown. If, for instance, request and response strings view is
desired, between W650 and the relay, in general settings reading we will do what follows:
1º. - Activate traces, from View, Traces menu
2º. - Open the general settings menu
The screen will display that group settings, on the left side bottom the relay reading request will appear
<0001><06/18/03 12:14:15>[0xFE 0x03 0x21 0x8A 0x00 0x16 0xFB 0xDD]
And on the right the settings response will appear:
0001><06/18/03 12:14:15>[0xFE 0x03 0x2C 0x3F 0x80 0x00 0x00 0x3F 0x80 0x00 0x00 0x3F 0x80 0x00 0x00 0x3F
0x80 0x00 0x00 0x00 0x00 0x42 0xC8 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0x00 0xFE
0x00 0xFE 0x00 0x06 0x00 0x06 0x00 0x00 0x01 0xF6 0xAC 0xB5]
This way, any request or mechanism to obtain information from the relay, can be viewed string by string.
There is another tool for tracing the relay memory: in W650 menu: Communication, Troubleshooting, any reading to any
address can be requested, the PC will form the string together with check-sum register.
