The SIM-EMU Configurator v2.2 is the dedicated interface for programming, calibrating, and managing the 6.02 Electric Multiple Unit (EMU) Simulation Core. This tool allows you to map hardware controls (cab desk), set train parameters (traction, braking, doors), and configure network protocols for driver training simulators.
Go to Parameter Table → Dynamics:
| Parameter | Typical Value | Description | |-----------|---------------|-------------| | Max acceleration | 1.1 m/s² | Full service acceleration | | Service brake decel | 0.9 m/s² | Normal brake ramp | | Emergency brake | 1.2 m/s² | Instant, non-overridable | | Jerk limit | 0.8 m/s³ | Passenger comfort | | Traction delay | 0.5 sec | Time from notch to power |
Tip: Lower jerk = smoother ride, but longer stopping distances. sim-emu 6.02 configurator v2.2
The jump from v2.1 to v2.2 brought several power-user enhancements:
The v2.2 configurator includes a flame graph view (similar to perf tools) showing which function blocks consume the most execution time. This is invaluable for optimizing legacy code.
Many engineers ask: Why not just use the built-in simulation in TIA Portal? The answer lies in scope and flexibility. The SIM-EMU Configurator v2
The existence of SIM-EMU relied heavily on the security flaws of the era, specifically regarding the A3/A8 authentication algorithms.
Mobile networks authenticate a SIM by sending a random number (RAND) to the card. The SIM uses its secret Ki and the RAND to calculate a signed response (SRES) using the A3 algorithm. In theory, the Ki should never leave the carrier's database.
However, SIM-EMU Configurator v2.2 was often used in tandem with "SIM Scanners." These tools brute-forced the Ki by exploiting the COMP128 vulnerability found in many 2G SIM cards. By sending thousands of specific challenges to a card and analyzing the data leakage, hackers could extract the Ki. The jump from v2
Once the Ki and IMSI were harvested, the Configurator was the assembly line. It allowed the user to write these harvested credentials onto a generic PIC/EEPROM chip. The emulator firmware on the card would then handle the A3/A8 crypto handshake exactly as the original carrier SIM would, tricking the network into accepting the clone.
Import symbol tables from STEP 7 (.sdf or .xls). v2.2 supports Unicode tags, arrays, and UDTs. You can manually add tags with data types: Bool, Byte, Word, DWord, Int, Real, String, and even Date/Time.
