Diagnostic Trouble Codes (DTCs)

DTC's indicate the status of your system on a node-by-node basis. Each node can activate a fault by setting it's diagnostic state to match a predefined code in the API.

Error codes can be found in the syslog located at /var/log/syslog, or by spawning the node manually and the node will output directly to the terminal like this:

$ cd /usr/local/polysync/examples/data_generator/
$ make
$ ./bin/polysync-data-generator-c
ERROR : polysync_lic : lic_validate -- process_features returned: 115
ERROR : polysync_core : (429) -- license is not valid
ERROR : main -- psync_init - ret: 115 

 In this case the error code is 115 which indicates our PolySync License is invalid. 

You can define custom DTC's to use within PolySync applications. We have reserved the first 32-bits, but feel free to fill up the upper 32-bits!
