You can always bind C code, of course, but today it's easy to end up saying, "well, but I could just get a working library in (Go/Python/Node/etc) and be done" and thus end your Pascal journey before it starts. There are certainly good libraries available, but many are old, Delphi-centric, and lack polish - haphazard accumulations from developers that are very "get-er-done" and unconcerned about reuse. That's where a lot of the code got written, and there's a definite focus on native desktop apps that remains. Basically, Pascal's current ecosystem exists in the shadow of one of the best RAD environments of the 90's - Delphi. And those compile times! A pretty well-suited language for game coding, actually.Īnd in terms of writing production code, libraries may or may not be a barrier. But the language, in the Borland dialects that most are using now, is somewhere in between C and C++ in terms of power overall: it's a little safer by default, still manual memory, but without needing to fling around quite so many pointers. Things like nested if-else with multiple conditionals are just a little more persnickity if you've been using C braces for decades. Pascal is unsurprising in a mostly good and sometimes frustrating way.

Tl dr is that if you create a RELEASE build, should be about 2 - 5mb for a GUI app, depending on the platform. Throughout the modelling process, in the SRP/CS Result tab you can view the current status of the assessment for all safety functions in accordance with EN ISO 13849-1 / 62061.This was written a few years ago with FPC v2.2 (latest is FPC v3.2), but generally matches my experience: If the required safety level PLr has not yet been achieved, this will be immediately visible in the form of warnings on the critical elements. The question list from EN ISO 13849-1 serves as a check list, for commenting on the entries. Of course, the tool also assesses the CCF (common cause failure). The Safety Calculator displays the data required for the respective device or structure. You can add additional documents, graphics, circuit diagrams or similar at any time, to add descriptive detail to the assessment.ĭo the components represent products for which the wear level depends on a number of operating cycles? Then an integrated conversion tool helps you to calculate these values from the information normally available. You only need to select between a device's various versions or application types once the basic device has been selected. The more libraries and components are created, the more difficult it is to identify the correct components in accordance with EN ISO 13849. They can simply be dragged from the libraries and dropped into the editor window. You will rarely need to enter components yourself, thanks to the extensive libraries. The next step is to model the individual safety functions, based on existing circuit diagrams. Step 3 – Model safety functions in accordance with EN ISO 13849-1
