  Hi, I would like to transfer the F940GOT-SWD-E program to a PC. in the photo the screen has become illegible. Do you have another solution to offer me? I am a novice and I would like help step by step. I ordered a new F940GOT-SWD-E and I receive it in 3 days. Thank you guys for your help. cordially  

If you register your software with mitsubishi, you can update to the latest version free of charge.   Steve

I not sure with that particular HMI but, usually unless you have the original source code or the source code was downloaded with the run time file I don't think you will be able to upload to modify (I may be wrong) Steve  

Your STL would equate to this in ladder   Steve  

The starting of the timer (SD T0) is an output function, this effectivley terminates the logic network (rung), the A     M      0.1 =     Q      0.0 Is then deemed a new network (rung). Try drawing it out in ladder to visualise.   Steve

Search and download the Mitsubishi analogue manual (JY997D16701) its a mine of information with practical examples.   Steve

What version Panelbuilder do you have? My version 3.83.01 has support for this display. Steve

I think you may be getting your analogues mixed up, The FX3U-4AD & DA are add on units that attach to the right hand side of the processor, these use and are addressed via the buffer memories 'BFM' The FX3U-4AD-ADP & 4DA-ADP are add on analogue units that attach to the left hand side of the processor, these are addressed via the special relay memories ie D8280, you can only use one of these analogue units to the left of the processor due to the built in onboard analogue channels. I would suggest you download the analogue users manual (Manual number JY997D16701). This is an excellent manual to explain all manner of analogues with FX PlC's   Steve  

For goodness sake save yourself time and heartache and buy a lead at only $6.00 it's a no brainer. SC-09 cable   Steve

These HMI's appear to be a chinese ripoff of the old siemens OP panels, if you google you can find a manual as to the connections and protocols to use the Mitsubishi FX range of PLC's with it, you will also need the correct software to program both, there are numorous manuals available for programming in mitsubishi.   Steve

Try running the install using 'Run as Administrator' to start it Steve

Which HMI are you using? Steve

Oops I didn't make it very clear that the 110v would be derived from an isolating transformer 230v primary / 110v secondary centre tapped to earth.   Steve

try changing the GOT communication port to 5556 Steve

Personally, I would go for 230v to 110v centre tapped to earth, this would reduce the touch voltage to 55v (unless of course you are dull enough to touch the two legs at the same time ), this is a much safer option.   Steve

Select Edit on top toolbar, Scroll down to ladder Edit Mode and select Write mode. (This can be set up to display on a dockable tool bar)   Steve

You can switch the view to 'instruction list' (alt +F1) from ladder, this should allow you to see if any odd or strange instruction or characters have been uploaded and corrupt the file. Any odd characters appearing or instructions missing can be modified here and the reverted back to ladder by alt +F1 again, just make a note of additions or removals so they can be put back if unexpected program modifications occur. Just a thought! Steve    

Something like this?      ( instuction  LDD)     Steve

Zombie thread alert! this thread is 10 years old.   Steve

The 'K' + number before the M500 (or in your case M800) indicates the number of 4bit groups or 'nybbles' to action. Example -  K4M800 would action M800 through to M815 inclusive, where as K2M800 would action M800 through M807 inc.

This is the best I can suggest at the moment, if i'm reading your post correctly. There maybe more efficient ways of achieving the required outcome, there are some pretty good mitsi programmers here.   Steve  

Generally the F28 is fieldbus timeout (this may be caused by a momentary loss in the fieldbus comms), to reset this type of fault a power cycle of the drive is required. this is assuming you are using a movidrive inverter   Steve

The 'AM' signal out from the VFD is an analogue signal which is selectable between voltage out at 0-10 volt or current out at 4-20mA. The 'FM' signal out is primarily for use with a frequency meter for remote speed indication this output gives a linear 24 pulses a second, the default setting is 1440pps at 60Hz it has a very low current out capability of around 1mA (I think) so this has to be taken into account if driving something else.   Steve

If i'm reading this correctly you could try a google search for 4-20mA to PWM converter (Pulse width modulation), Or 0-10Volt to PWM converter.   Steve

Try here Instruction set.   Steve
