Dialog: Add Signal
Tip
In CODESYS version 3.5 SP17 and higher, the J1939 configurator is no longer supplied with a parameter group / signal database. The old database is no longer supported.
However, you can post-install a DBC database in the J1939 Manager. A database can be purchased, for example from CSS Electronics: https://www.csselectronics.com/screen/product/j1939-dbc-file-pgn-spn
If you do not install a database, then you can also configure parameter groups and signals manually on the User-Defined tab.
Signals are added in the same way as for parameter groups. |
