![]() There are a few thousand 'rungs' that would be required to implement the whole machine, but only about ~60 that really drive the operations of the machine, that you'd need to look at to understand why it's, say, stuck on step 12 (because the robot hasn't finished running program #12) or why it won't switch to auto mode or whatever. You're right that it's just easier to read than deeply-nested parentheses and boolean logic combinations. Then at the topmost level, where most of the debugging will need to happen, I used ladder to drive the sequencer. I use structured text to implement most of the details of the subsystems I needed to build (talking to the robot, safety controller, PC, and IO), FBD to abstract those subsystems out to the level of "a robot that runs a variety of numbered programs" rather than "this Denso with this calling convention and this IO on Ethernet/IP". In Rockwell-land it was the default, in Beckhoff structured text is the default. I miss some of the polish of the text editor that comes with Visual Studio by default (no dark mode in the editor, and no CTRL+R, CTRL+R to rename instead of F2, when you do rename it brings up a dialog box instead of editing in place, and then it brings up a massive confirmation dialog with "OK" highlighted but the tab order screwed up so you have to mouse down to "OK" instead of just confirming the change that I just typed in and confirmed with the "Enter" key).ĭoes anyone want to share their Twincat 3 keyboard shortcuts (Tools-> Import and Export Settings-> Export-> Uncheck all, check only Options-> Environment-> Keyboard) and a quick reference to it? Or any other coping mechanisms? It's a text editor that's mostly standards-compliant, I can work with that. I've started writing more of this machine in Structured Text I hope no one unfamiliar with text-based programming has to maintain it but it's just so much less vexatious than their ladder editor. The Tools-> Customize-> Keyboard-> FBDLDIL.InsertContact and myriad other commands are blank by default. ![]() The Menu key on your keyboard (between right ALT and right CTRL) does nothing, neither does SHIFT+F10. You can't even access the FBD/LD/IL menu with the conventional Windows ALT+letter shortcuts, and even if you could, none of the menu items have a shortcut. Twincat 3 looks lovely in its modern Visual Studio-based environment (Dark theme FTW!) until you get to the ladder editor. Except no, that's for the obsolete Twincat 2 editor. It just feels so tedious.įortunately, Infosys has a list of keyboard shortcuts. You've got to take your hands off the keyboard, right click the edge of the editor, choose 'insert network below', right click the one-pixel line, choose 'insert contact', double click the "?" and type your tag name. In Twincat 3, everything is a mouse operation. And if there's a pattern I use frequently, I can create a template in Notepad++ or Excel to simply do some text processing and make a Sensor or Actuator or Fault routine. I can refactor a section of ladder rungs by copy-pasting the whole lot into Notepad++ and find-replacing my XICs to XIOs or changing tag names in bulk or whatever I need to do. Iinsert a contact in RSLogix 5000 by simply typing "XIC" for eXamine-If-Closed or "BST" for "Branch STart" and so on the editor is snappy and most instructions are easily memorized. I'm new to Beckhoff from Rockwell, and while Rockwell tools are a morasse of license issues and undocumented limitations and version incompatibilities and legacy code, one thing they do have going for them is their mnemonics are quick to enter.
