Yesterday we published the new version of PLC Simulator Online. Here you can find a list of all the changes.
UX changes
We made many changes to improve user experience.
Overflow for Variable Table and Diagram for better display on mobiles
Variable Table and Diagram windows have now fixed size with overflow added for better navigation. The toolbox and action bar is now fixed in the same position.
Rung and branch highlight when selected
Ladder Logic components are now highlighted blue when selected.
Highlight rung power rails, branch, and wire when simulation on
All elements are now highlighted green when on. Highlight clearly shows the path of the signal to help better understand Ladder Logic.
Highlight element variable red if not configured
When the element variable is not selected the name is highlighted with red colour.
Assign variables warning popup
Assign variables to all red highlighted elements! popup will appear if you try to start simulation without configuring all items.
Disable simulation when editing the ladder diagram
If you tap or click on any of the Toolbox or Action Bar elements, the simulation will turn off.
New elements
We added four new elements. More is coming soon.
Two new timers (TOF, TONR)
We added Start off-delay timer (TOF) and Time accumulator (TONR) that you can select through element properties.
Counters (CTU, CTD)
We also added Count up (CTU) and Count down (CTD) counter.
Code improvements
We made two significant changes that you won’t be able to see directly in PLC Simulator Online.
JS to TypeScript
We refactored the code from JavaScript to TypeScript. That will help us to easier catch bugs and improve your experience.
Performance improvement
We also improved the cycle scan performance. The cycle scan is fixed to 66ms, but some scripts required more than 50ms. We were able to reduce that time to 15ms in most cases.
PLC Simulator Online Roadmap
We hope you like the changes. To see what you can expect in the future please take a look at the project road map.
