Then, it is up to the AO1's state machine to decide what to do, depending on the event and the current state.

So AO1 will have two events in its queue: one from the timer and another from AO2. The scheduler extracts the first event (from the timer) and invokes AO1, and then the AO1 state machine processes the second event (from AO2). This should work nicely. Somehow I had the impression that only one event could be processed during a single scheduler cycle, but in this case both events are handled sequentially from the queue. Thanks again!

I have attached a state machine for your AO1 that would do what you describe. This assumes that your AO2 produces events ACTIVATE and DEACTIVATE for AO1. --MMSQuantum LeapsMon, 18 May 2026 20:48:12 -0000https://sourceforge.net/p/qpc/discussion/668726/thread/332fc1589d/?limit=25#7f69https://sourceforge.net/p/qpc/discussion/668726/thread/332fc1589d/?limit=25#59b9Hello Community!

I don't know if this can be a problem,... It looks like a problem to me because this is very confusing and does not really model the reality. Your job is not to "cheat" (to make it "work" in this particular stage of your modeling), but to capture the true essence of the behavior. Also, I'm not sure if I understand your use of state hierarchy. For example, the OPEN transition should be directly from the "lidClosed" to "lidOpen".

It didn't make any sense that if the toaster if off that it should be turned on simply by opening and closing the door. It should stay off. My fix: Signal OFF from the doorOpen state should just transition directly to the off state in doorClosed (not using history). Signal CLOSE in doorOpen transitions to history (placed on doorClosed not heating, and is not shallow).Mike_STue, 07 Apr 2026 12:27:08 -0000https://sourceforge.net/p/qpc/discussion/668726/thread/4214e9c1b6/?limit=25#e0b1/ac03https://sourceforge.net/p/qpc/discussion/668726/thread/184edefc12/?limit=25#62f5Hi fellas, Great topic! :D https://doorstop.readthedocs.io/ (not IBM's product; this is 100% FLOSS , git-friendly, actively maintained) CheersLeandro Tue, 31 Mar 2026 13:56:55 -0000https://sourceforge.net/p/qpc/discussion/668726/thread/184edefc12/?limit=25#62f5https://sourceforge.net/p/qpc/discussion/668726/thread/01aade0e0b/?limit=25#3074Hi Mark, As a commercial licensee, please contact Quantum Leaps support (support@state-machine.com) for the QSPY source code. --MMSQuantum LeapsThu, 26 Mar 2026 12:21:36 -0000https://sourceforge.net/p/qpc/discussion/668726/thread/01aade0e0b/?limit=25#3074https://sourceforge.net/p/qpc/discussion/668726/thread/01aade0e0b/?limit=25#3fa4We use qspy on a Raspberry Pi and have always built a Linux binary for arm64 for this purpose.

It seems that you prefer the very traditional code partitioning, so just do that. Specifically, instead of manually "removing the delimit portions that QM controls", just generate the traditional header files (.h/.hpp) with your class declarations ( $declare {} directives). Then simply include those QM-generated headers in your external source files (.cpp).

Consequently, you can implement all/most/some actions and/or guards on your state machines as (member) functions of your state machine class. You can then implement those functions in any number of files: completely outside QM or within QM as regular files or external files. If the implementation files are outside QM, they won't be obviously overwritten when QM re-generates code.

I have 40 “sensors” connected over an RS‑485 bus. For each sensor I have an orthogonal state machine inside a dedicated AO (let’s call it SensorManager). I also have a separate AO responsible for managing the RS‑485 serial interface. The problem: Each of the 40 sensor state machines may need to send a Modbus request, which means they would post an event to the AO that handles the serial line. However, I cannot allow all 40 sensors to request...Giulio Dalla VecchiaWed, 11 Mar 2026 11:26:16 -0000https://sourceforge.net/p/qpc/discussion/668726/thread/ca70cfd09e/?limit=25#636fhttps://sourceforge.net/p/qpc/bugs/397/?limit=25#9696here is versionAnonymousTue, 10 Mar 2026 20:02:44 -0000https://sourceforge.net/p/qpc/bugs/397/?limit=25#9696https://sourceforge.net/p/qpc/bugs/397/Manage External Tools Parser Error C:\\qp\\qpc AnonymousTue, 10 Mar 2026 19:59:45 -0000https://sourceforge.net/p/qpc/bugs/397/https://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3-windows.exe/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:24:05 -0000https://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3-windows.exe/downloadhttps://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3.sha256/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:23:04 -0000https://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3.sha256/downloadhttps://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3-macos.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:23:04 -0000https://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3-macos.zip/downloadhttps://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3-linux.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:23:04 -0000https://sourceforge.net/projects/qpc/files/QP-bundle/8.1.3/qp_8.1.3-linux.zip/downloadhttps://sourceforge.net/projects/qpc/files/QP-Cpp/8.1.3/qpcpp_8.1.3.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:22:04 -0000https://sourceforge.net/projects/qpc/files/QP-Cpp/8.1.3/qpcpp_8.1.3.zip/downloadhttps://sourceforge.net/projects/qpc/files/QP-Cpp/8.1.3/QuantumLeaps.qpcpp.8.1.3.pack/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:22:04 -0000https://sourceforge.net/projects/qpc/files/QP-Cpp/8.1.3/QuantumLeaps.qpcpp.8.1.3.pack/downloadhttps://sourceforge.net/projects/qpc/files/QP-C/8.1.3/qpc_8.1.3.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:22:04 -0000https://sourceforge.net/projects/qpc/files/QP-C/8.1.3/qpc_8.1.3.zip/downloadhttps://sourceforge.net/projects/qpc/files/QP-C/8.1.3/QuantumLeaps.qpc.8.1.3.pack/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:22:04 -0000https://sourceforge.net/projects/qpc/files/QP-C/8.1.3/QuantumLeaps.qpc.8.1.3.pack/downloadhttps://sourceforge.net/projects/qpc/files/QTools/8.1.3/qtools_8.1.3-windows.exe/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:21:05 -0000https://sourceforge.net/projects/qpc/files/QTools/8.1.3/qtools_8.1.3-windows.exe/downloadhttps://sourceforge.net/projects/qpc/files/QTools/8.1.3/qtools_8.1.3-linux.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:21:05 -0000https://sourceforge.net/projects/qpc/files/QTools/8.1.3/qtools_8.1.3-linux.zip/downloadhttps://sourceforge.net/projects/qpc/files/QTools/8.1.3/qtools_8.1.3-macos.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:21:05 -0000https://sourceforge.net/projects/qpc/files/QTools/8.1.3/qtools_8.1.3-macos.zip/downloadhttps://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-macos.dmg/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:20:05 -0000https://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-macos.dmg/downloadhttps://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-windows.exe/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:20:05 -0000https://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-windows.exe/downloadhttps://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-windows.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:19:05 -0000https://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-windows.zip/downloadhttps://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-linux.zip/downloadQP Real-Time Event Frameworks & ToolsTue, 10 Mar 2026 01:19:04 -0000https://sourceforge.net/projects/qpc/files/QM/7.0.3/qm_7.0.3-linux.zip/downloadhttps://sourceforge.net/p/qpc/discussion/668726/thread/7ab79bcfd4/?limit=25#7300Okay, thank you very much! :)dillangMon, 09 Mar 2026 09:22:35 -0000https://sourceforge.net/p/qpc/discussion/668726/thread/7ab79bcfd4/?limit=25#7300https://sourceforge.net/p/qpc/discussion/668726/thread/7ab79bcfd4/?limit=25#a67fOkay, thank you very much! :)dillangMon, 09 Mar 2026 09:22:34 -0000https://sourceforge.net/p/qpc/discussion/668726/thread/7ab79bcfd4/?limit=25#a67f
