Error indication - WMT700

WMT700 provides advanced self-diagnostics for monitoring the status of the wind sensor and the validity of the measurement data. You can use the diagnostics as follows:

• WMT700 checks the status of the internal operational software at each reset by verifying the CRC checksum of the software. The software check is not made periodically; it is only made at each reset. If the checksum is incorrect, WMT700 does not start up. If the checksum is correct, WMT700 continues by calculating the CRC checksum of the parameter memory. In case the parameter memory is corrupted, the sensor replies with the text Parameters crc error upon startup. In case the parameter memory checksum is correct, WMT700 replies with the text ready as shown in the example below.

ready.

• To check the status of the wind sensor, include the status code item \er in the data message. You need to convert the status code to a binary number to verify the status. An error code does not indicate that the wind data is invalid.
• To check that the wind data is valid, include the \va item in the data message.
• To check other diagnostics-related data, include the required items in the data message.
