That's because they are connected with rs232 to the PLC, but this version has only this c200h direct connection. These do have rs232 too, but only for use with the programming tool(what's the big idea?). I was thinking that maybe the newer PLCs like CJ and others might have the c200h direct connection, but i guess not. The connector is the same as the peripheral connector in CPM and CQM, but i guess they use some different protocol or something funny.

It figures. This really pisses me off. D*mn omron can't do anything right. There's no point in having a million different protocols and connections other than ripping money. If only i could find the specs for the connection.

get slowdown from http://members.aol.com/bretjohn/ . It's free and works in dos. If that doesn't help, i guess you need to get a slower machine.

You know, the thing is this: the password has nothing to do with IP protection, since you are protected by law anyway. Secondly, if you let people to get to the PLC anyway, it's pretty much the same if they **** up the PLC or the rest of the stuff that's there. Use a lock in your cabinets. That way, when there's a problem, atleast the lock can be smashed, if required, but people who have no business messing with the stuff can't access it. I would never let the situation be such, that some PLC company guy would have to come crack the pass for me and let the whole operation sit.

From experience, minilass works fine with atleast a 100 Mhz 486 machine with dos. I haven't tried any faster machines. How fast are the machines you've tried with and did you use dos with the slower one?

Bollocks. The passwords are there just make things hell, when you are trying to repair the machine. Don't give us the IP"rights" bullshit. Anyone who wanted the program could have it by many other ways, but when someone tries to maintain a machine, that's been operating for years without interuptions, then where the hell are you gonna come up with the password? I say crack them all. Who cares about some 5 years old PLC program, unless you want to repair the machine. Stop whining about cracking the password protections. I'll just laugh at you, when you have to reprogram some nicely complex program just because you can't get the password and noone helps you crack it.

Or DR-DOS, which you can get for free. http://www.drdos.net/

I've tried minilss with 3 different 486 laptops, 25 Mhz, 50 Mhz and 100 Mhz. It worked perfectly with the 25 and 50Mhz, but not with the 100 Mhz, even when the clock speed had been halfed with the computer's own slowing down feature or with slowdown. Minilss seemed to work fine at first, but crashed, when one tried to compile Obj>Diagrams or the other way around. Well, long story short, i had to reinstall dos and after that it worked fine even at 100 Mhz. I can't be sure if the reason was just that the system had somehow gone bad or maybe some compaq's weird program messed the thing, but i haven't put any of the compaq stuff back after the reinstall. I even asked omron for the source, but they said they didn't make the program and they don't have the source and plaa plaa. Some company called Control Software made it, but i have no more information about them.

Excuse me, but to my knowledge that's a pinout, not a wiring diagram. You can't see from that, if the cable has loops for example, like so many rs232 cables do. Anyway i decided to try the cn131 cable and it seemed to work. Still this is how i would've liked this whole conversation to go: |Me: does anyone have the wiring diagram for the c200h-cn222 cable, that connects between the |c200h-pro27 and the PLC? |- |Someone: I know/I measured the cable and it's a straight through cable. |- |Me: Thank you very much.

3 reasons: 1) I have the connectors and i can make the cable myself. 2) This is not some job i'm doing for someone. This is totally hobby/learning stuff only and i don't have a client to charge money for. 3) The cable would cost some outrageous amount of moula, which i don't have, and out of principle wouldn't pay to get a piece of wires. Really, it's just a few pieces of wire, how can it cost? Manufacturing the cable costs like a cent or something, so how come it costs me 1000 times more? I think there should be some kind of sense in the pricing these things. Just because it says omron on it, doesn't mean it's anything else than those few pieces of wire. It really does piss me of, that you pay huge amounts of money for the hardware, that does all the actual work, and then you have to pay that amount or more again for the nuts'n bolts to make it all work. That's just plain weird in my book. You might think, that it's fine to pay the money for all the little things, but i think there should be some kind of focus on what's really worth it, would make everything so much easier. (i just wanted to thoroughly explain this point, so there wouldn't be any misunderstandings, not to rant) I don't want to turn this into a conversation about markets and stuff. If someone can provide the wiring diagram, that's good, if not, let the topic die. Off to sleep.

That's very possible. I measured another cable, which is c200h-cn131, which is a i/o cable for c200 with which you can for example connect a NT20S to the c200h. It's a straight through cable, but who knows what kind of traps they put in the cables just to make them incompatible. I don't want to break anything and it's a simple thing to measure the cable, if only someone had one. Maybe i'll give it a shot this weekend, if noone else answers. I'm not quite sure what you mean with "modifications noted in the document", unless you mean the that the connection has extra signals compared to rs232.

Well thank you, i do appriciate it. Anyone with the cable, it shouldn't take more than 5 minutes to measure the wiring, so please help me out.

What are you talking about? First of all, i asked about all the info you had on the port in the other conversation and you said you don't know anything else, also that doesn't give the wiring diagram. I don't know what the h-link and tool signals are and if they are needed here, so i do need the wiring diagram no matter what, but thank you anyway for the PDF.

I have 3 C28K's and you need 3g2c7-lk201-ev1 to convert the weirdo port to rs232, which i only have one. Unfortunately it's not just a TTL-RS232 voltage converter, cause it's a huge box with tons of chips in it and dip switches to select connection speed. If i had the skills, i'd reverse engineer it, but i don't. If you have the box, then it's just a matter of making a very simple 9pin rs232 to 25 pin rs232 cable. Hopefully someone with the skills would reverse it and make a simple microcontroller (f.e.with microchip PIC) version of the box.

I have 5 NT20S ST122-v1, 1 NT20M with RS232C, 2 CPM1A and a CQM1 cpu21. Now after reading the spaghetti instructions of all these machines, i still am not quite sure what i can connect and where. At this point i want to test, if the NT20S' work, but apparently i can't connect them to neither CPM1A or CQM1, because the moon is out of focus compared to the galaxy jfj23423-jjrej222 and it's not inline with the line from jupiter to planet zorg. The NT20M i can apparently connect to the CPM1A with the CPM1-CIF01 RS232-converter. This is all official plaa plaa from omron, i don't mind doing the stuff the unofficial way, because this equipment isn't going to be put in any industrial use. I just want to make them connected, so give me all the hacks you can think of. Are the omron protocols open for viewing, so one could make a converter between the PLC and the HMI? Also i don't have the special cables, that are needed to do all this omron special connections, but i do have connectors, so i can make the cables myself, if someone gives me the wiring diagrams. I also need a wiring diagram for the cable between the c200h-pro27-e programming console and both of the PLCs. If someone can figure out the way of connecting a PC to the cqm1 through the peripheral interface without the cqm-cif01 (or whatever), like talked about in the cpm1 hack conversation, i'd be thankful. Why is it, that the computer's RS232 needs to be converted into some omron special protocol and then the NT's only work with RS232, except for this and that, but tih sand that aren't compatible, and either the PLCs have only one RS232 or none? Does this sound reasonable to you? I don't see why this has to be so complicated.

Is the information about the c200h bus interface available? I'm considering a microcontroller, that would convert it to host link or nt link (information about those links also required), though i don't think i have the resources to do it atleast not very fast. I didn't get them from ebay and they really aren't good as anchors. What i don't understand is, that if a PLC has RS232 and the weird omron connector, and the NT has RS232 and the weird omron connector, how come they can't work together. I have 2 guesses, but i think i'm gonna keep them to myself. Apparently you can use the CQM1-CIF02 in place of the CPM1-CIF01 with the CPM1, atleast that's what they've drawn in the CPM1 operational manual. The cable between the CPM and the C200h-PRO27 console is C200H-CN222 (or C200H-CN422). If someone has one of those cables, could you measure if it's connected straight or do some wires cross and which ones, thanks. About the pdf about the CQM1-CIF02. You wouldn't happend to have the pin numbers for the PLC connector, would you?

Well that i do understand, but there are all sorts of protocols, like host link, nt link, direct link whatever link, which some know, some don't and none know them all. Thanks for the cif02 pdf, i'll have to check it out.

It's a design fault, cause it makes everything more complicated (needing the box i mean).

ChrisKozanecki no one is forcing you to use it, why are you whining? Jay, you don't need to modify the board, if you have the connector. Secondly, i wasn't talking about in a point of view of some company. Companies can afford the things, but individuals can't. A $100 for a box that has the name omron and includes 2 chips that cost around $0.01 is a bit much. Also the PLC should be designed in the way, that you don't need all sorts of boxes to program them. It's a waste of money, space, time and nerves. Try carrying 10 different boxes to be able to program different PLCs with you. It's a design flaw.

I think it's great, that people hack these things. For example without the SP cable hack, i couldn't program the SP PLCs. Where would i get a cable for them? Anyway, in the drawing there isn't any components at all. Are you sure it's safe to use? I mean that does the CPM1 have the rs232 drivers in it anyway or is it just "luck" that it can handle the voltages of rs232? Looking at for example the SPxx/SKxx cable, which you can find in the omron section (and it works fully) it has a resistor to prevent damage to the PLC. It'd probably be more safe to add the resistor like in that cable. About the CQM, i noticed from the universal cable insctructions (can be found from the omron section), that CQM has different ground pin than others. It's not directly related, cause that's for the what ever external box CQM needs, but maybe the pinout for that pin is different from the CPM in the PLC connector also.

I'm not quite sure what you are asking, but an open contact is one where the electricity can't go through it, and a closed one means the electricity does go through it. Normally open contact means, that you have to, for example, push a button, so the contact closes and the electricity flows through it. Normally closed means that when you, for example, push the button, it cuts the electricity. The picture is weird. I don't understand why there's open and closed contacts in both the physical categories.

Thank you very much.

Would be nice, if someone, who has the terminal operation manual for the NT20M HMIs, would scan it and put it in the DL section. I couldn't find it anywhere, not even from omron's million sites (which isn't really a miracle).

Sorry, but that's not the manual i'm talking about. I have that one. The manual's "ID" or whatever is V001-e1-2. The manual you upped here is for the software for those HMIs, but thanks anyway.

I don't know what CMS means. Anyway what i can tell from pic, number 1 is a capasitor, 2 capasitor, if it's a box, not round, 3 diode (not zener i'd say), 4 is a transistor of some sort (there are a few places on the net where you might be able to find out the data, but i don't have the URLs right now), 5 that's a tough one, try measuring the resistance between the points that you've marked with the letters, 6 capasitor value is pretty hard to find out, unless you have a good meter.
