Bit worried about programming an Fx3 using the old  Win E software .  Can it be done ?

I too have this problem.  My VFD is a FRZ024 1.5K. It will work for a while but after switching it off and switching back on it just displays 'err'  and no more action whatsoever. I've also noticed that there is no 'click' from the built in power relay on switch-on when this happens.

Hi there, I have a Siemens S7200 , circa 1997 that has one or more duff relays. How practical is it to replace them ? ( I'm a Mitsi man really ) Cheers Eric Thacker

Ahhhhh... that explains a lot. When D128 was reset.... so was D129 to my consternation. Many thank for replies all, I'm new to these data registers and not very good. I was at work this morning, took the picture with my phone, got on this forum using it and attached the picture. Ain't technology marvellous. Thanks again all, I'll probably be back again tomorrow, Cheers Ecca PS Medoc is much better than GX Developer, it's miles too slow when you're monitoring things.

Decimal digits

I am using double word instructions so I'll take a look at this tomorrow....... Cheers Ecca PS Post what code ?

I set up a data register as a counter because the normal counters have insufficient digits then sometimes the counter counts backwards. I add to the data register to achieve the count and reset it by subracting itself from itself. Can anyone tell me why it goes backwards , or better still how to achieve a 6 digit totalising counter. PLC= FX0N, data register =D0 Cheers, Ecca

Thanks for all your help.... I'm using D0, when I get back at it on Monday I'll try d128...... Cheers, Ecca

I use the relay M8033 to retain data in a data register which works OK when switching between run and program but when I power down completely and then switch back on, the data register in question resets to zero. What am I doing wrong ? ( PLC=FXON ) Cheers Ecca

Thanks for replies all. I've tried all ways and I can't get GX Developer to import medoc files. What a great shame.

As per the title.... how do I do it ? Cheers, ET

Which input do I use ? Where will the value of the encoder be found ?

Thank you Paul. Can I do this as many times as I want to with overlapping positions? Great Eric Thacker

I have to carry 3 USB to serial adaptors around with me ! One works with Mitsi but not with Klockner etc. They're certainly not a standard item.
