Steps
Install the Okuma Open API SDK (OkumaAmerica/Open-API-SDK on GitHub) matching the OSP THINC API version running on the target control
Ensure the target environment is either an actual Okuma machine with a P-type control, an NC-Master hardware simulator, or PC NC-Master run as Administrator, with the API Notifier service running
Launch the calling application via the Okuma Startup Service so THINC-API is initialized before your code runs
Call CMachine.Init() once, from the application's main/GUI thread, before accessing any machine data
Read machine status, alarms, or program data through the CMachine object's exposed properties/methods, then call Close() on shutdown
Known gotchas
THINC-API calls must run on the main/GUI thread — using a system thread-pool thread (e.g. BackgroundWorker or Task) causes intermittent failures
Init() will fail outside an environment where OSP NC Software and THINC API/API Notifier are actually running — it cannot be exercised from an arbitrary offline dev machine
API help files are shipped as .chm and must be locally unblocked (and not stored in a path containing '#') or Windows will refuse to render them
