Dialog: Add Parameter Group

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 413: 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 414: 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.
“Description”	Description of the parameter group
