Hi
my question may sound a kinda awkward but anyway i have in my mind.
I wanted to know how long would it take a person with no knowledge about PLC to become an advanced PLC programmer? ( with a great IT background)
Best Regards
Ilia

Hi Illiaamini,
That question is hard to answer as it depends on aptitude. Having an IT background may or may not help. If you are learning the lessons and things seem to "click" while doing the practices, you may have the aptitude to become advanced within a few years. I can tell you that even with my 18+ years of experience, I continue to learn new ways to do things all of the time. Just keep enjoying the lessons and things will happen as determined by your ability.

Hi shahpour, actually problem is that when I use this pulse(80 ms) made by timers in simulator it works. But when I use this pulse in a program to replace cpu clock pulse(100 ms) it doesn't work. I want to increase the speed of my machine which has cpu 317-2 pn/dp having 150 ms scan time. It's program has more than 100 FB & FC. Thanks & Regards

Hi Ajit, I have not seen your PLC program but from what you describe I think the CPU is not able to reset the watchdog timer because of a hardware fault or a program error. I recommend checking the "diagnostic buffer" and see what error you get when the CPU stops.

Watching these two videos in the library can also be helpful:

Hi, only this not timing beside this all program running ok and no error reported. CPU doesn't stop. I doubt that program is big & having 150ms scan time so no time left for this timer (80 ms) during scanning. I write this pulse by timer in ob 1 & check there only. I want to use this in FB 61 where cycle time calculated via cpu clock bit(100 ms). Should I write this pulse in fb 61 itself.

If the CPU does not go to the stop mode and the system fault LED is not turned on, the program is not that big to exceed the cycle time. You can test that in the FB as well but I think there are also some factors that are causing the logic to not work the way it should.

Hi Mondi/Shahpour! Looks like we are about to finish basic instructions. I can't wait for extended instructions, technologies and communications sections.

Thanks for all the work you've done. This is a great resource for learning a really difficult subject...What Siemens software are you using in the videos? Is it a free download?

Hi there, Thanks for your positive feedback. Below is the list of software we're using for the courses you see in the library:

STEP7 V5.5
STEP7 V5.6
STEP7 V13
STEP7 V13 SP1
STEP7 V14 SP1

STEP7 is used for programming Siemens S7 PLCs and comes in two versions of basic and professional. You can find a free trial download of both versions just by googling STEP7.

The basic version is a good choice for those who just want to learn PLC programming. You can find more info on that here: http://w3.siemens.com/mcms/automation-software/en/tia-portal-software/step7-tia-portal/step7-basic/Pages/Default.aspx

Hi,
I have just started working on TIA portal 14. I wrote a test program in LAD logic & want to convert it in STL logic like i do in Step7 V5.5 via View then select preferred language.
Is this option available in TIA portal ?
