The list below shows the versions and builds of 20-sim 4C that have been released. You can check the version and build number of 20-sim 4C in the About box.
20-sim 4C 2.1

2.1.13 (11 september 2023, build 5100)

Bug fixes:

Bachmann: fixed a token parser problem with the Bachmann target when the GoAhead webserver support is enabled.
Fixed: 32th bit for the bitget/bitset/bitclear function did not work

General Improvements:

Bachmann: check the MCF GUID against the model GUID also during MCF update to prevent updating an MCF that does not belong to the running module.
Add template support for the 20-sim 5.0 SinCos function
Register 20-sim 4C 2.1 as code generation target for future versions of 20-sim newer than version 5.0

2.1.12 (24 April 2019, build 4748)

General Improvements:

Bachmann: add a new SVI status variable #mcf_write_status that shows the status of the parameter storage to the MCF during run-time parameter changes.
Register 20-sim 4C 2.1 as code generation target in the upcoming 20-sim 4.8 release
Changed: No need to store the MCF path as absolute path when it is stored in next to the TXP file (default). Fixes opening the project in newer 20-sim 4C versions.

Bug fixes:

Fixed: C-code implementation of the bitget function was wrong. It should return 1 when the requested bit is 1 and 0 otherwise.
Fixed: Initialization of a boolean vector or matrix could fail when spaces were used after a , or ; in 20-sim
Fixed: Bachmann: the run-time parameter change detection triggered an unnecessary MCF write at start-up
Fixed: Bachmann: run-time parameter change detection triggered sometimes a double MCF write

General Improvements:

Add 20-sim 4C version tokens
Add 20-sim 4C version information to the model configuration file (MCF)
Stored connections in the TXP rely on correct ordering in the TCF. Extra validation using the port name and component name added. Mismatched connection are deleted.
Bachmann: add 20-sim 4C version information to the compiled module
Bachmann: Do not always write the MCF on exit
Bachmann: Add checksum to the MCF. No/corrupt/invalid MCF? Don’t start the task
Bachmann: Check MCF checksum before applying changes
Bachmann: Add a GUID to the MCF and the compiled module to make sure that the MCF and module belong to the same model version
Bachmann: Add extra log messages around MCF writing and I/O open/close to facilitate debugging
Bachmann: Use FTP for file upload if possible (faster uploading for large models)
Bachmann: Update our template based on the Solution Center V2.25 C-module template (gcc 2.95)

Bug fixes:

Fixed: Bachmann: Using the DI232 in 20-sim 4C 2.1.10 gave a compile error.
Fixed: Bachmann: Misleading status message “submodelname received RcpStop” during PLC boot.
Fixed: changing ip or hostname for an existing target did not result in an online status without closing/reopening the project.
Fixed: Memory free errors Bachmann (double free under certain fault conditions).
Fixed: Code generation with modified output directory in 20-sim results in a project at the wrong location.
Fixed: Bachmann: Update minixml code to v2.11 (bugfixes, memory allocation/deallocation fixes).
Changed: Allow collecting all I/O intialisation errors before aborting the task initialisation.
Changed: Bachmann: Module does not abort SVI variable registration anymore after the first error.
Changed: 20-sim 4C CHM help was always on top. This hides the 20-sim 4C window on small screens.

20-sim 4C: Fixed: Connections lost when switching to the TCF from the cache folder
Bachmann: Taskname “aMODELNAME (1)” => “aMODELNAME_log” (prevent double task names)
Bachmann: Improve Bachmann task timing; only listen to the MIO_SYNC_IN signal to prevent jitter on the start times
Bachmann: Stop a running model does not work when the connect and compile phase are not yet green
Bachmann: Stopping a model stores the end values in the MCF. Restarting the model should not restore all values from the MCF. Only parameters and initialvalues should be read from the MCF. All other values are calculated by the model.
TS-7300: Fixed TS-ADC16 usage resulted in a compiler warning

2.1.9 (19 February 2016, build 3795)

Connection: adding a new connection jumps back to the top of the list
Documentation: TS-7300 XDIO1_2 was called XDIO1_3 in the manual
