Cheers Paul Ked, it clicked in my head last night as i was driving home, what a dumb booty i am. Now i look at it, its hardly the biggest task to work out, suppose thats what you get for having 2 hours sleep Cheers for the help, always appreciated Regards Mitch

Cheers for the help Got another annoying problem now but its programme wise this time which ive asked about before. Initially i wanted to bring every output on via a button which i managed by using the following command line: FMOV HFFFF K4Y000 K3 But now i only want to bring outputs Y000-Y020 on and im having trouble getting my head around the correct command line. im taking it that the above line works as follows: Move the hex word value 'FFFF' out to a group of 4x'K'4 starting out at Y000 x 3? So that gave me 4x4x3 which is 48 but because its only 40 output it simply ignored the other 8? am i correct in thinking this and is there an easy way to do it, say via decimal rather than hex to simply signify i want high outputs from Y000-Y020 Regards Mitch Well ive managed to do it via the same command line but using the values: FMOV HFFFF K1Y000 K5 This gives me full output on 4x'K'1x5 = 20 out Im up on how to use and convert hex to decimal and ocatal and back etc and im fine on PLC's for the most part and as simple as this must be, im having trouble seeing it clearly in how to give the correct initial word value to bring on just the outputs you want? Regards Mitch

Sorry i havent replied earlier, been on holiday. I took the PLC out and wired it up with just power and a single switch to check every input and output after i cleared the programme and the block still did not work so i sent it for repair and its now ok so it looks like it was a hardware fault internally. Cheers for all the replies, didnt mean to start world war 3 though

Allready checked all the voltage terminals, +24V on all of them Regards Mitch

Hi all, got a bit of an odd problem. Ive rigged my PLC (FX2N-80MT-ESS/UL) so that when it sees a certain button conbination, it turns on all the outputs. Now this all works fine in the sense that all the LED's on the PLC come one, but for some reason the block of outputs Y4-Y10 do not output any voltage. Every other light, output does output so im suspecting its purely a problem with that block of outputs. However is there individual block of circuit for every 4 outputs of is it all on one board and is it easy to check the condition of the board(s) if necessary? Thanks in advance Mitch

Cheers panic mode. I thought it would mean Hex but wanted to make my life easier and just ask. Looking at the manual it actually is pretty obvious, i guess it does pay to read the manual sometimes Cheers for the info about the programme issues as well, much appreciated Many thanks Mitch

Thats brilliant Gambit, thank you very much. One quick question, what does the H stand for before the actual hex word output FFFF? Also once thay have been activated, how do i turn them off and once turned off, i take it they will resume from whatever the programme is then asking of them? What i mean by that is when they are de-activated, it does not interfere with the rest of the programme and will carry on as normal? Cheers again Mitch

Hi all. New to the site so hello to everybody and thanks in advance for any help or advice given. I need a bit of help with a query ive got. Is it possible to use a special command or certain function to force all the outputs on at the same time. Basically i want a lamp test button on my test rig and want to use a dig-in to control all the outputs for as long as it’s pressed. I can’t seem to find any direct special function or command to do this so is it somehow possible to do it using the move command. I know you can group outputs into one big bunch but then how would you tell them all to turn on. Would this be done using a set word size for instance so that if say the hex word 'FFFF' is sent, all outputs of the specified group turn on? It guessing its simple to do and I’m pretty clued up on PLC's but I just cant get it to, or at least think how to make it do what I want. Any ideas or solution would be greatly appreciated and an example of the code would be even better. Thanks Mitch
