13.5 Error memory structure
The error memory contains 22 error messages. A query is responded with
11 data sets with a colon as separator and can be queried using the
following command:
Query:
?:2300:00::cc<CR>
Reading the
last 11 error memory entries.
Query: ?:2301:00::cc<CR>
Reading the
first 11 error memory entries.
Error memory data set structure
These data sets consist of 11 byte and are encrypted in 21 ASCII characters
prior to data transmission. Example: The byte 0x23 is converted into the
ASCII characters 0x32 (‚2’) and 0x33 (‚3’).
– Byte 1 consists of 1 characters,
– Bytes 2 - 11 consist of 2 characters.
Therefore, a response consists of 1+(10 x 2) = 21 data bytes plus
separator.
A data set always delivers the date, the time, the faulty control loop, the
device status, and the error message.
Example of a response:
First data set: !:2300:fb:10b01060f372280000002:
(with 21 bytes)
Second data set: 20b01060f38100001... ...:80
(beginning of the second data set after 21 bytes
of the first data set and of the separator [1 byte])
