J1939 Add-in 6 Version History

2021-09-22 - Version 6.5.0 - Part of PCAN-Explorer 6.5.0

Improvements:

  • The Claim Address and Release Address buttons in the Connections window show the address to be claimed or released in the tooltip of the buttons and in the long hint textes shown in the PCAN-Explorer status bar
  • J1939 database updated (2021-08)
  • DTC Monitor: Performance of sorting a larger number of list entries/DTCs improved

Bug fixes:

  • An Access Violation error could occur while disabling a J1939 connection
  • PCAN-Explorer froze when a project was loaded that had a periodic multipacket message configured to be sent to a specific destination address, which requires an address to be claimed

2020-12-04 - Version 6.4.1 - Part of PCAN-Explorer 6.4.1

Improvements:

  • J1939 DTC Monitor: Active DTC entries for which no corresponding DM01 message was received within the expected time frame (2500 ms) are displayed greyed-out
  • J1939 DTC Monitor: New possibility to copy list entries to the clipboard
  • J1939 DTC Monitor: Added online help files

Bug fixes:

  • The J1939 DTC Monitor files were also installed under Windows 7 and 8 if a 'Complete' installation was performed, although the application only supports Windows 10

2020-10-30 - Version 6.4.0 - Part of PCAN-Explorer 6.4.0

Improvements:

  • J1939 database updated (2020-07)
  • New possibility to reject incoming TPCM.RTS messages for specific PGNs so that a TPCM.ConnAbort is sent to reject the data transfer
  • Automation interface: New property PCANJ1939Node.PGNsToRejectOnRTS
  • Value 127 of SPN 1216 (Occurrence Count) is now correctly displayed as 'Not available'
  • Includes new experimental J1939 DTC Monitor Add-in that can be used to display and request Diagnostic Trouble Codes (DTCs) and other diagnostic messages (Windows 10 required)
  • When specifying a Manufacturer Code for the J1939 NAME field, a new Lookup dialog box can be displayed to search and select a Manufacturer Code from a list of all registered manufacturers

Bug fixes:

  • If the properties of a J1939 connection were shown in the Properties window and the connection claimed an address because a Request for Address Claimed message was received, the property values in the Property window were not updated
  • When a DA Global request for a PDU2 PGN was received, multipacket messages in the Transmit List that were configured for a specific Destination Address (not the Global Address) were also sent as a response to that request
  • If a J1939PG symbol with a specific length but with multipacket enabled was defined, and the first received message had a length of 8 bytes or less, an internal data buffer was created that could only hold a maximum of 8 data bytes. When a longer message was received later, only question marks were displayed for the values of those Variables that were located beyond data byte 7

2019-12-02 - Version 6.3.4 - Part of PCAN-Explorer 6.3.4

Bug fixes:

  • Auto-calculated checksum values for messages TC3, ENGSA, and ENGSC were incorrect

Changes:

  • If the SPNConversionMethod (SPN 1706) of a DM01 DTC was set to 1 (see J1939-73, 5.7.1.13), the SuspectParameterNumber (SPN 1214) variable in the same DTC was decoded/encoded using SPN conversion method version 1 (pure Motorola format). Now version 3 is used by default for encoding/decoding SPNs

2019-08-01 - Version 6.3.3 - Part of PCAN-Explorer 6.3.3

Bug fixes:

  • Too large values for TotalMessageSize variable in TPCM.BAM or TPCM.RTS messages caused an application freeze or crash. Wrong values in TotalMessageSize variable now triggers a TPCM.ConnAbort message with abort reason 9 for RTS/CTS sessions, and a silent abort for BAM sessions

2019-06-07 - Version 6.3.1 - Part of PCAN-Explorer 6.3.1

Improvements:

  • New possibility to receive and trace Error Frames with J1939 connections
  • J1939 database updated (2019-04)

Bug fixes:

  • Since version 6.2.0 the default values for the following J1939 parameters were not correctly initialized:
    • CTS: Number of accepted packets (should be 255)
    • Number of Re-CTS (should be 3)
    • RTS: Maximum number of packets (should be 255)
    • Number of retries (should be 3)
    • Interpacket time (should be 50 ms)
  • A new Reset button in the Options dialog box on the J1939 page allows to reset these 5 parameters to their default values

2018-12-13 - Version 6.2.2 - Part of PCAN-Explorer 6.2.2

Improvements:

  • Received BAM multipacket messages are now reassembled even if monitoring is not active and no address is claimed
  • J1939 database updated (2018-08)
  • Support for 46 new auto-calculated values from the updated J1939 database 2018-08
  • New possibility to sort the J1939 Auto-values lists in Options and Project Settings dialog boxes

Bug fixes:

  • Auto-calculated checksum of J1939 symbols TC3, ENGSC, and ENGSA was only 4 bits in size instead of 8 bits

2018-07-20 - Version 6.2.0 - Part of PCAN-Explorer 6.2.0

Improvements:

  • New feature to automatically calculate J1939 rolling counters and checksums when transmitting the PGNs TSC1, XBR, AEBS2, TC3, SAS, CN, ENGSC, and ENGSA

2017-06-09 - Version 6.0.12 - Part of PCAN-Explorer 6.0.12

Bug fixes:

  • The industry group drop-down list of the J1939 NAME field in the Properties window was empty and no industry group could be selected
  • If no data length was specified for a J1939PG multipacket symbol, any variable located beyond data byte 7 was not initialized with its default value
  • When the last J1939 connection was removed from the project, the message list columns were not updated to the non-J1939 column configuration
  • Sending a J1939 message by assigning a signal value, e.g. in a VBS macro, did not set the message type of the automatically created transmit message correctly, the message did not have the J1939 tag
  • String variables with a length greater than 8 bytes in multipacket J1939 symbols were only decoded when the variable had an SPN value assigned

Changes:

  • J1939 symbols are now only assigned to messages that have the J1939 message type (which show a J1939 tag in the Type column). Previously, J1939 symbols were also assigned to 29-bit messages, for example when the protocol of the connection was changed from CAN to J1939 and the Receive/Transmit lists already contained 29-bit messages

2017-04-07 - Version 6.0.11 - Part of PCAN-Explorer 6.0.11

Bug fixes:

  • When a J1939 transmit message was edited, the Priority field in the Edit Message dialog box was not correctly initialized so it could contain an incorrect value
  • J1939 database fixed: SPNs 695, 696, and 897 were missing in message TSC1

2016-12-12 - Version 6.0.9 - Part of PCAN-Explorer 6.0.9

Improvements:

  • The PGN field in the Edit Message dialog box is now editable when a custom J1939 transmit message is created
  • J1939 messages have their own icon in the Type column of transmit lists, and messages that require the transport protocol for transmission have an additional mark
  • J1939 database updated (2016-11)

2016-10-13 - Version 6.0.5 - Part of PCAN-Explorer 6.0.5

Improvement:

  • J1939 database updated (2016-07)

2016-09-02 - Version 6.0.3 - Part of PCAN-Explorer 6.0.3

Improvements:

  • The J1939 database now includes SLOT values according to J1939-71 Appendix A. SPN and SLOT value assignments are used to show range names according to J1939-71 chapter 5.1.5

Bug fixes:

  • If the system was not restarted for a long time, the J1939 Add-in returned wrong timestamps so that cyclic J1939 messages (non-multipacket) could no longer be transmitted
  • Transport protocol read session were refused by sending a TCPM.Abort message even if the connection was in monitoring mode and/or the claimed address did not correspond to the incoming request

2016-06-28 - Version 6.0.2 - Part of PCAN-Explorer 6.0.2

  • J1939 database updated (2016-03)

2016-06-09 - Version 6.0.1 - Part of PCAN-Explorer 6.0.1

  • First Release
