Dialog: Add Parameter Group

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.

Table 30. Database

CODESYS shows all parameters of the database on this tab.

Find

String for filtering the PGN list

Reset

Reset the filter for showing the full list

Filter

Only PGs of the selected type are shown.

Add PG

Adds the selected parameter group to the TX signal list. Multiple selection of parameter groups is possible.



Table 31. User-defined

On this tab, you can created user-defined parameter groups.

PGN (18 Bit)

Unique number of the PG (0...262143) that is calculated from the four subsequent parameters. You can type in this value directly into the field.

PDU specific (bit 0–7)

Evaluation of the value depends on the value in PDU format.

  • If PDU format is between 0 and 239, then the message is addressable and the field contains the target address.

  • If PDU format is between 240 and 255, then the message is a broadcast message and the field contains the group expansion.

PDU format (bit 8-15)

Protocol Data Unit

The format determines whether the message can be transmitted with a target address or always as a broadcast message.

Data page (bit 16)

Selection of the page for the PDU format (currently always 0).

Expanded data page (bit 17)

Not used: For future expansion.

Name

Name of the new parameter group.

Length (bytes)

Length of the parameter group (in bytes)

Priority

Priority of the parameter group (0..7). Priority 0 is the highest and 7 is the lowest.
