- In this video, we're going to be covering the hot topic of FUNCTION BLOCKS, how to create them, how to implement them into your programs and then how to execute and monitor them live in your PLC!
We'll be using Mitsubishi GxWorks 2 and a Mitsubishi Fx PLC to test this out!

Just amazing how you explain the function and how to do it🤩
Glad you liked it!
Very professional, clear and easy to follow for a complete amateur like me.
Looking forwards to more !
Glad to hear it! We're pretty busy at the moment in terms of training however we will have more available shortly!
Thank you very much! this kind of content is gold! As one almost always ends up learning by himself... so this saves a lot of time
Glad you enjoyed it!
Brilliant, this solved a huge gap in my knowledge! Thank you so much
Great to hear!
Congratulation!
You are a real teacher.
Nice job.
I am unhappy because I can sign you one like only.
Thank you! 😃
Thank you for your super clear and awesome videos!!
You're very welcome!
@@ScantimeAutomationTraining Thanks again! Rewatched it. A fantastic tutorial.
@@ScantimeAutomationTraining I wish you had a paid Mitsubishi gxworks 2/gxworks 3 course!
great details.
Thank you! Cheers!
Hello and thank you for the good introduction to the topic.
I also find your voice pleasant and clear. What drives me to the brink of insanity is that background music loop. Maybe because as an ADHD person I am easily distracted, but maybe just because it is awful.
I'm also looking forward to many more good videos, and maybe it can be done without such a loop?
Glad you enjoyed the video and thanks for the constructive criticism :)
Easy to explanation.
Glad you think so!
Just wow
Thanks!
Thanks for the vid! How do get a multi-rung function block not to have a enable input? I have a rung or two with some TON's
Let me check
I was wondering if you will do anything on displaying time remaining or counting down for timers. I have managed to create a structured project with various timers, but am looking to have the remaining time shown on a display and cannot see how that can be done.
Many thanks for some really informative videos
I can have a look at this :)
Can you answer to this please, how to communicate between GX Works2 plc and ix developer 2.40 sp2 SCADA
Will try and make a video on this!
Hi.I have a PLC program already lock some function block.can you guide me how to unlock it
Chances are you won't be able to without a password if it is PW protected.
How to update Input and Output of Function after I add more input and output?
You can right-click the block and select the new block at the bottom of the drop-down menu!
Can you recomend me some documents about FB in Mitsubishi PLC.
We may do a video on this!
@@ScantimeAutomationTraining i hope soon.
How to use Timer IN function Block?
We'll have a look at this.
HOW TO USE TIMER IN FUNCTION BLOCK
Thanks, will have a look!
The ladder logic you are using here is flawed. In industry, a start pushbutton utilises a normally open contact, whereas a stop pushbutton utilises a normally closed contact. You are working on the premise that both buttons have normally open contacts. This is actually not allowed for reasons of safety. This is a very basic mistake to make and very misleading for your target audience.
We tend to see in industry nowadays the Stop PB being wired as a NO Contact similar to the Start PB due to the Emergency Stop Button being used more-so for safety, for example, if an accident was to occur, operators would now aim for the E-Stop to stop the process and not the Stop PB as Stop PB's can be used for Cycle Stops which would continue running the process until it reaches the end of its cycle.
We also see less and less PBs being used on the shop-floor too as these are now being replaced by HMI or SCADA screens which contain these buttons, as these are on the screen, these would both act like Normally Open contacts requiring the Stop PB to use a NC Contact in the program.
It ultimately depends upon how the company has wired its electrical contacts, this would dictate how the program is to be designed.
Please note, these tutorials are not about how to write programs but more about how to use certain aspects of the programming software. When we design programs for companies, there are a lot of variables which can influence certain programming methods that we use.
@@ScantimeAutomationTraining Point taken on HMI and lack of pushbuttons. However any hard wired devices that would have any impact on safety would utilise normally closed contacts as the subsequent circuit design would highlight a wire/termination break in a similar way to the closed loops used in safety relay circuits. Safety considerations always trumps operational matters. I also take your point regarding not being a programming course.
As mentioned previously, the Stop PBs aren't used as safety signals in a lot of industries we have worked in as the safety is usually done through the E-Stop, this is then fed back to Safety Relays as NC contacts which may be PILZ for example which then sends signals to the PLC for monitoring purposes.
If the Stop signal was considered safety on a process, this should also be wired to safety relays and monitored by the safety circuits but as it is for control, this tends not to be the case which is why we are allowed to control operation such as starting and stopping through an HMI screen, but not allowed to control the EStops through an HMI screen.
If an HMI was to fail, you wouldn't be able to stop the process via that Stop PB anymore, but the EStop would.
