What is the difference between "static" and "temp"/"temporary" variables?Find out here! Link to my GoFundMe: www.gofundme.com/f/let039s-fi... Thanks for watching! Stay safe and healthy out there!
Great content bruder! Just starting my journey in the Siemens TIA Portal world after working with Allen Bradley PLCs for 3 years, I hadn't worked with Siemens since the Step 7 MicroWIN, very good explanations. Thanks.
The videos I have watched are very usefull and informative. It was pleasure for me and to watch you and learn ... Alles klar and gut danke für your effort..
Best explend! Thank for your efforts! If possible plz make a tutorial on realtime industrial automation program using OB,FB, FC with your lovely elaboration Thank you!
There was a motor control program i made. i learnt that some features like interlock functions, operating hours, and operating count would only work as intended if they were in a static area.
Hi Hegamurl! Please, make video about using Modbus RTU communication betwen s7-1200 and another equepment, like HMI or frequency driver. Thx for your video, your great teacher)
Im impressed by how well TIA portal runs on your pc, is there any trick to optimise the program? I have a decent pc both RAM and processor wise and it just stutters with TIA
Can a edge memory bit be a temporary variable? Or will it count up with each cycle as long as the input is high? Great content as usual, would be great tho if you could give a brief rundown on different applications of the content in use in Automation
Edge Memory Bits need to be static, as they have to "remember" the status from the last cycle. Great advice with showing applications, I'll keep it in mind!
@@demurch0 Basically YES. But... 1. If you only use the subroutine once, you could simply use a global memory bit (not good practice) 2. You could add the edge memory bit as input to your subroutine and externally connect a global memory
Thanks for the explanation. So the only reason one would use temp variables is reduce memory usage. Can you please tell what is the practical usage of having a temp variable apart from reducing the memory size and why would we use them.
Sometimes you just one to restart functions from the beginning. Any data remaining can create a mistake. If you start a cycle, you don't want the previous cycle to ruin your process.

Excellent question! OB1 is only interrupted (and never cancelled), so the temporary data is not lost and still in the data stack. After OB30 was executed, the rest of the program just goes on as it normally would.
Better if you could have shown a Move block to transfer data from Temp Variable to a Global memory variable. Viewers would have easily realized that Temp variable is actually incrementing...
