Carel 1tool: Software
The software is structured into several interconnected modules, each dedicated to a specific aspect of the controller's application development:
As the HVAC industry moves toward IoT (Internet of Things), CAREL is integrating 1Tool with cloud platforms. The latest versions of 1Tool include configuration wizards for (the cloud monitoring platform). This means settings configured locally in 1Tool can automatically synchronize to a cloud dashboard, enabling predictive maintenance algorithms.
Understanding CAREL 1tool: The Ultimate Development Software for HVAC/R Automation carel 1tool software
Utilize text note annotations inside the FBD sheet. Explain complex logic formulas or interlock conditions so future technicians can service the code easily.
To maximize efficiency, 1tool utilizes a hierarchy of functional blocks that cater to different levels of programming complexity: : Advanced functional blocks that combine a control
Organize screens into "User Loop" (status viewing), "Installer Loop" (setpoint configuration), and "Manufacturer Loop" (advanced PID tuning protected by passwords).
: Advanced functional blocks that combine a control algorithm with a predefined user interface. These "plug-and-play" components significantly shorten lead times by allowing developers to import entire functional units at once. Conclusion AI_ for Analog Inputs
Implement a strict prefix system for variables (e.g., AI_ for Analog Inputs, DO_ for Digital Outputs, Par_ for Setpoints/Parameters) to make the data dictionary easily searchable.

Hi,Amos
Thank you for the insights.You mentioned free software to open the .eps files.Can you recommend free option for editing them?
Sure no problem – Inkscape is the best free alternative Inkscape
I have trouble opening an eps file with Inscape…. 🙁
Go try another EPS file. EPS files are not all the same – they could have several different information embedded and sometimes you just need to try it with another software. Adobe Illustrator always works for me.
I tried the Gravit SW and it is imposible for working. Almost not responsive for clicks, seems like very very heavy SW. Not recomended.
Works fast and fine here. Maybe it uses a lot of ressources in your browser – go check it out with another browser maybe.
Inkscape sucks in my opinion. Amos, are you saying that it’s better than Gravit?
I only worked with Inkscape for a limited time and I think it has a deeper learning curve than Gravit. Gravit is way more limited than Inkscape at this point.
Thank you for the video walking through Gravit! This is my first time working with EPS files and you were informative and clear in your explanations. Thanks!
for the eps file that you used in this video, can I extract; for example the bulb as a transparent png using Gravit.io?
thanks!
I really don’t know I think that should work according to the time I was creating this video.
I want to express my gratitude to stockphotosecrets, for the online EPS converter. It just got me fixed.
You are most welcome! Such comments make me very happy because we work hard to give back to the community.
Wouldn’t a PDF be better nowadays than an EPS?
Hi Derek, that is subject to designer’s preferences and PDF is a perfectly acceptable format for graphics. But generally speaking, EPS format is better for editing.
I can open EPS files using IRFANVIEW with the correct add-ins. IRFANVIEW is also free.
Hi TL, thank you for mentioning this. Unfortunately, most people are not familiar with installing software plus plugins into that software just to open EPS files. But we keep it in mind for the next update.
