Description

The DateTime OBDFault Custom Field Definition block defines a data store that is allocated according to the number of faults in the user application. The purpose is to map a particular type of data to a particular fault. The user can update and read the data at run time when it is required. The data can also be used by protocol handlers and other algorithms.

In the "Custom Field Name" field, provide a unique name; this is accessible from anywhere in the model. Duplicate names are not allowed. 'Storage Class' identifies the behavior of the data on the target. Volatile data will return to its 'Initial Value' on every startup. NonVolatile data will be saved in EEPROM, and return to the last written value on startup. The 'Initial Value' can be overridden by the DateTime OBDFault Custom Field Defaults block.

This block accepts either datetime or timespan structure data types.
