nbucska, Actually I only need to calculate 8 bytes of data and there are lots of limitations as to what those data bits can be. I manually unpicked about 500 pages of code and on the first scan have narrowed the options quite considerably. However, thankfully, the MRF came though with the...

Hi, I am in a spot of trouble. I am working on a machine using a 115U PLC within which is an IM308 card but the EPROM within this card has lost its contents I need to write a replacement has anyone got any ideas on calculating the address of the IO on the system? The system uses two ET100...

JesperMP, Many thanks I had not hurd of this forum. Nick

I have found that to speak to the rack I need a PG631, and I have one, hurra! but I am missing the cable, a 734 cable from a PG631 to a 500programmer interface card. Siemens no longer have any details on this cable. Would love to get hold of one if anyone can help? And yes JesperMP this...

HART isn't that a current loop protocal? An Siemens TTY is current loop too? sounds hope full Do you know which Siemens system you are using yet? and what are the protocals your trying to match at the other end would that be HART?

skogsgurra Thats brilliant many thanks. SattControl are now owned by ABB and I am in the process of taking up my querriers with them. Nick

Hi all, Has anyone every hurd of a very very old looking controler called "Salt Controls" the only other identifying feature is that is has "Malmo Sweden" written on it. Its large white and flat with 32 inputs and 28 outputs and model number is probably sc-09-25 I would like to replace the...

By X-Programmer I think you find more luck looking for CX-Programmer. this is the latest Omron software and is good to use, not that syswin was bad. One thought I have installed a few laptops with PLC software. Sometimes the internal achitecture of the laptop means that COM1 is the internal...

Davidvinch, Yep its a biggie ant it! I wouldn't mined a copy of ProWorx myself if its knocking about, thats very kind of you. Could you email it to me or would you like a postal address? Nick

davidvinch It would seem that the people with the purse strings here are not playing, many apologies for getting you hopes up there. You are of course right in as much as learning is learning and is always beneficial. Some features of the Modicon stuff are particularly clever, but the 584...

Hi guys, Anyone know anything about the old Siemens 110 system? I have a counter unit to program for this rack and I am not sure how to communicate to the rack even? If anyone still has any manuals or catalogues for this system I would be very grateful for some guidance Cheers Nick

I have just been though the back of our stores and we seem to have a couple of P190 programmers in there let me know if you need one maybe we can help.

We use a P190 dedicated programmer for this PLC system so cant help I'm affried but if you can find n of these programmers that would do you. I would say that toi be given atwo 584 systems is not so much a gift as someone trying to find a home for a very large paper weight eh ;-)

CTG, The KNKT entry field is for two byte length inputs, as you describe, the first KN is the channel number and the second defines wither the channel is by-polar or unipolar. The KN entry should be 0 to 7 for a 470 card, as there is only 8 channels. After entering a valid card start...

CTG, All STL progrms start in Object Block 1 OB1 so start your code here. you cant use all comands in an OB so it is common for your first line to be an unconditional jump to a program block say PB1 the PLC cycles though the program and starts again at OB1 when its finished. At the end of a...

OK there are two ways of doing this. the first is simpler to understand and the second is more complex but you may find ultimately that it reduces the amount of math’s in you main program. 1) Siemens analogue cards must be addressed as a peripheral address. so set the address of the 470 card...

Hi guys, I just picked up a Siemens card from our stores to find the crystal missing from the card. If anyone has the same card out there and would be kind enough to look at theres and tell me the value of the crystal that would be great. The card I have is a 6ES65 310-3AB11 its the expansion...
