Included components¶
fieldbusaccess (binary)
Dependencies¶
libsapcore.so.3

Bugfix where cyclic receive messages were not received during a short startup period (around 1 minute).
Known issues/ deviations¶
Running RT with a configuration that has more than one connection with same can interface index (can0 + can0 but with different node ID for example) will result in an error message in console. Trying to create same sync-signal to Data Engine fails. This could be considered a warning and will be updated in future releases.

Default CAN instances updated with FA instance index (0-3)
CanSocket driver instantiated with multiple instances.
Error signals now unique to specific can instances e.g. fieldbusAccess_J1939Error_CAN0 (changed from fieldbusAccess_J1939Error)

fieldbusaccess (binary)
Dependencies¶
libsapcore.so.3

Changes/Included features¶
Bug fix - Free memory queue now done when unwanted source PGN is filtered and discarded
Known issues/ deviations¶
1.1.10 - 2018-08-30¶
Address field in configuration used as source address filtering.
Rx signals in FA now allows broadcast messages with 0xFF in configuration file or a specific peer-to-peer source address from configuration source-address field
1.1.9 - 2018-05-31¶
Added environment variable option FIELDBUSACCESS_SKIP_OS_BOOTED (export FIELDBUSACCESS_SKIP_OS_BOOTED=) that disables wait for hasOsBooted flag from system during boot. Enables user to prioritize boot order (can-interface and Data Engine needs to be available during FA initialization).
Fixed bug where connecting to Data Engine no longer reconnected if DE were started after FA during boot.
1.1.8 - 2018-05-02¶
Fixed bug so cyclic receive blob messages now sends received SA as first byte (previous only the initialized SA were shown)
OSHasBooted was trapped in a loop when CCAux API failed to retrieve parameter (imx6). Now tries until timeout and then continue startup procedure.
1.1.7 - 2018-04-09¶
Bug fix - Cyclic timeout detection now works together with suspend-resume
1.1.4 - 2018-02-13¶
Fix bug where Cyclic Received BLOB messages triggered DE signal change (previous message) of incoming signal and next signal in list!
1.1.3 - 2018-01-08¶
Prevent configuration file to be overwritten during installation of FA
Initialized cyclic receive blob (previous-value) messages with FFFFFFFFFFFFFFFF
Reset timers after a suspend so that cyclic receive error detection is responding accordingly
1.1.2 - 2017-10-26¶
Fixed bug where a signal value change except byte 1 in CAN-frame did not send updated value to DE as it should
Fixed Cyclic transmit buffer that never were emptied
Fixed installation script bug where VERSION where not parsed correct
Some generic iMX6 updates added
1.1.1 - 2017-08-17¶
Changed CANBusError type from blob to Unsigned Short
Update Qt ARM install script
CAN-Bus error detection, Bus-off etc. detected and sent to DE on fieldbusAccess_CANBusError
FA attempts to restart can-driver on CAN-Bus error
Debug mode no longer writes data to output
Fixed issue with cyclic receive values only working with unsigned int
Float values received correct in DE
Fixed console info bug where cycle transmit values where prompted in output as cycle time x 3 (timeout interval) instead of cycle time from configuration file
Fixed cyclic Error_Ok sent when same value is sent as last received on can-bus
Updated FA (ARM) so it starts all can-interfaces from conf. file accordingly
Fixed bug where CAN interface index was used to set the CAN baudrate (CCAux counts the index from 1 and not 0)
Fixed Cyclic Transmit and Receive of BLOB TP
Added send Err_Ok to DE stack_error signal after cyclic error detected and signals resumes
Added txqueuelen 10000 to CAN interface settings
Changed how instances are created for J1939 and how it should use BusNr found in the configuration file. When a new instance of a J1939Wrapper is created it will now not accept the instance number as the argument. With this addition, it’s now possible to use can0, can1 etc. by setting the busNo in the configuration to 0..N. The previous solution always initialized can0 since the default value was set to 0
Cyclic receive blob values is now stored and compared and only sent (according to configured cycle time) to DE when updated values arrive on the can-bus
Updated FA J1939 Error message to be sent as one Blob DE signal merging err_code and err_info into one signal
1.1.0 - 2017-03-30¶
Fixed Cyclic Receive so it now handles multiple signals
Updated fieldbusaccess with type-safe char, changed to signed char
1.0.1 - 2017-03-02¶
Fixed received blob size, changed from 255 to 4085 bytes allowing for max blob limit
Security timeout sleep issue fixed. Now sleep for 10ms instead of 1s in case of buffer overrun
Updated program arguments, args are no more dependent on position, ./fieldbusaccess -h for additional info
Added debug argument -d, default off but with argument additional debug information is sent to console
Updated FA J1939 specific messages (PDU2 < 240). Now adds in initialization correct and messages received (Rx on_change and cyclic)
1.0.0 - 2016-12-08¶
Fixed bug where SPN buffer was not cleared properly when sending to fieldbusaccess
Messages in Tx list were wrongly added to APL_Filter, this has now been removed. The filter is only for incoming messages. The bug resulted in Rx buffer overrun when only transmitting messages and another node is transmitting the same messages
Fixed bug where FA tried to add same PGN to filter list for every SPN in its sublist. This made FA emit an stack error equal to ‘Error 2 of class 2 in unit 3 with info 65028 is occurred’
0.8.2 - 2016-10-28¶
Updated J1939 Err status message now including the whole 16 bit error message and not only the last 8 (number) part.
0.8.1 - 2016-10-27¶
New argument added to FA [INSTANCE_NAME]. This will be used as data engine client name
Solved issue when transmitting Blob messages and no signals were updated
0.8.0 - 2016-10-19¶
Added custom nodeid address list capability to Fieldbus Access runtime from configuration
Fixed bug where subscribe to sync signal during Sapcore::Connect is lost if Data Engine is not running
0.7.8 - 2016-09-28¶
Argument handler, FA now requires a configuration file as an argument or it won’t start
If no argument is given a help text is displayed. It’s also possible to check FA version with -v option as well as -h for help
Updated FA with race condition validation. During boot FA waits for OS_IS_BOOTED then setups can-interface according to configuration file. Afterwards FA connects to DE, validates connection and then subscribes to signals according to configuration file
0.7.7 - 2016-09-07¶
Added Fieldbus Access packages with support for DE 3.0.0
Update to .run FA installer package scripts
Fixed ‘ARM’ bug where blob values were not transmitted from DE
Added CNF.h with configuration settings
Changed define bug where sniffer_mode and device_mode where mixed up! Blob support added from FA to DE
Increase in stability/performance and timer resolution. Updated timer resolution, messages per cycle and call of stack to 1ms from 10ms
Changed logic between producer/consumer within fieldbusaccess runtime
Parses Diagnostics values from configuration file (DM1/DM2) and handle them accordingly
Switch between consumer/producer to better match with configuration tool and GUI application
Updated Fieldbus Access config tool (Support for BLOB and DM1/DM2)
0.7.1 - 2016-04-27¶
Data Engine installation files updated to version 2.1.0
Added new fieldbusaccess installation patch v.0.7.1 for ARM
Added new fieldbusaccess installation patch v.0.7.1 for VM
