Does the relay have a N/c and N/o contact? 95-96 wired to the coil 97-98 wired for indication to PLC with logic change. Or maybe wire thru the overload to the coil and tap off to the PLC input without logic change? If it's that simple then why not?

But not on a FX1n.

I thought long and hard before putting 'not possible.' 'Not practical' gave too much hope. Govind Lathkar also asked for a short program. I've be interested to see an example, practical or not.

STL = SFC?

RS485 to RS422 repeater? Some can be set for different rates on each side. I've never done it though.

Oops, yes H4 is correct, I counted from 1 instead of zero. [TO H5 K0 H0 K1] H5 is the head address. K0 is where it is stored in H5. H0 is the value that is stored. K1 is the how many words. [FROM H5 K11 D100 K1] H5 head address K11 is where the data to be read is read from. D100 is where it is written. K1 is the length.

I would say that what you require is not possible. (I think it would require lograrithms and real number multiplication at the very least. Is there room enough for log tables in the D registers? )

Try the attached *untested* function block. I'm not using TO/FROM as MOV uses less memory. (Not that you'll run out on a Q006H, moan, if only I could get my hands on one of those, grumble, shouldn't be allowed, moan...) The program is setup for 1 channel 0-10V Head address H5, input start H50 which might just work. If you use it let me know if it works! Edit : I forgot to program the error bit, we can add that later. Q64AD.zip

I've just deleted a 200 word rant about my history with AB! But it's all the usual stuff. I just find their approach very annoying so I'm probalby not the best person to ask for an impartial view. I'm going to start a conspiracy theory that they have those lie-detectors connected to there support phone lines - in fact I've almost convinced myself already.

That's the only bit I'd disagree with but what's it got to do with me?

How about a 'can anyone program a XXXXXX' request? We just want to know who Company A is!

Was this what you were trying to do? Can I give in S500 PID application STF+PID Set value with RS485 communication and read actual value with analog input 4? (500 series (S,E,F and A)) - KS01162 Yes this combination is possible. Please see attached document. read more Yes this combination is possible. Please see attached document. http://78.136.49.242/branch/database/sendf...mp;m_culture=en A bit late I know.

"D" = Double "-" = Subract "P" = Pulsed Subtracts K150000 from the 32 bit value of D2510-D2511 and place the result in D2010. Edit : I think that's the right way round now.

I was 'taken' by the large CC link to Inverter FB's. All that functionality in a box would make for tidy programming. But I'll write one and start with a few functions for now and work up.

There a lots of useful function blocks on the Mitsubishi website but... they are all for IEC! Can anyone convert these for use in GX developer? Or create a PDF of the raw code so I can attempt a conversion? (I'll promise to upload any successful conversions.)

http://forums.mrplc.com/index.php?autocom=downloads&showfile=670 It's almost as if someone saw this coming.

I never got it to work with the Q series temperature card. I have looked at the programming example and the only other thing that may be worth monitoring is the data link status to your remote module (not M100 = data link ok in the example program from SW80.whatever in the master station). Maybe a falling edge on M100 to set Y79 then X78 resets Y78...as per the sample? It may be worth trying to send the Y79 signal during normal operation to see what happens and maybe try to change some parameters to see if it sticks?

The inverter side probably* handles comms similar to CC link. For that you set the frequency you want AND set the frequency write bit. If the freq. write bit is not set the freq. doesn't change. I know that's a bit vague but it may help.

I don't have IEC. I've installed the demo but can't open any of the function blocks. Edit : I don't think this is going to work...I'll have to write them from scratch.

Just had a look at the powerpoint example in preparation for an upcoming project and it looks like you need to monitor the "Initial data processing request flag".

First thing to try is to put a 'restart' bit in parallel with SM402. Down power on the remote station. Power up. Activate the restart bit and see what happens. I had a similar problem on a Q series temp. input (not CC link). I could not get it to restart after a wire-break/ unplugging with similar symptoms. In this case it wasn't a problem to PDPU if it happened.

Try the Siemens forum ?

Is this one resolved now?

I'm up to 200 lines of (untested) code already. This should definitely be chargeable to complete. I think a search of the site will show lots of 'hour run' type questions. On one of the more specific questions : Parameters - I don't think you will have to change anything from the default values.

There's a different specification in the Hardware manual and the Programming manual. Should be no problem then. My days are only 12 hours. Let the coding commence!
