About time. Probably there is a Modbus protocol included in the latest version of CX-One. Hope they have also fixed the help system up quite a bit. It is really pretty cryptic in places and not all that helpfull. Hopefully they have also included help for some of the older functions that are still available in the new PLCs. I have to get out my Omron Digital Technical Library CD quite often as some of the older functions are still quite usefull. I really do not know which version of the SCU I have but probably not V1.3 I guess. Thanks for the comments.

I have not seen one of these for many years. Having trouble remembering much about them. I think you will need a manual to decipher some of it but cannot find one in the Omron website. ILC is interlock clear, used in conjunction with IL (interlock). This is available in the newer Omron PLCs. Timers will be on delay I believe. kr is probaly a bit or word type but cannot remember. Hopefully there will be someone here that will have a manual and can help you further.

Have you tried this? It works for Modbus. Omron Modbus Protocol Also, sometimes I find word "0" does not work. Try word 1.

Can't read Pim.

I have just had a look at the help in CX-Programmer fo +F and # is not shown as an option. In fact # means BCD and & means binary/HEX. The instruction help clearly states that all words have to be floating point to IEEE754 standard.

Kind of funny but I get the problem on both my desktop and laptop with only one PLC in the project. Will have to look and see if there is a pattern with one type of PLC.

If you use BCD thumbwheel switches each will take up 4 inputs and the result in the input channel will be BCD (0-9). Do this quite often for timer values etc. Thew CPM1A has an instruction ANDW. You can use this as a mask to move the digits you wish into an individual channel. For example, if a channel contains the number 1234, ANDW channel no #0F00 to channel no will move the digit 2 into the result channel. Hope this helps.

Try E-bay for the host link. In the US they are quite often there at a cheap price.

You get a simulator when you buy CX-One.

Tell me about it. Pain in the "A". Have not found a cure but also have not installed the latest "fixes" from the CX-One wbesite.

I would still put in an interface of some kind due to the fact that an external device can be replaced easily. Guess I am old fashioned.

Distance of run? If the run is a lot shorter on the other machine where it is now working OK, it may be getting weak. Have seen this with Mitsubishi remote masters several times.

Would strongly suggest you use an interface like a relay or something. External devices are easy to change - outout modules on cards are not. I only use transistor outputs to drive relays or fully protected LED indicators. I do not believe they are protected.

Here is a link to a very good book on the CPM1A. Different Omron PLC but will help you get the right idea. Omron book

Correct. You can also run CX-Integrator by this method and CX-Programmer from within Integrator. Drove me nuts trying to find it both ways. The help is lousy.

Which lights are flashing on the RM201? Usually a problem with remote I/O means a problem with the RT201 at the other end.

Correct. Used hand held programmers for a long time.

Have a look from the other side of the fence. Open thine eyes! When I do a job with generators, I put pass word protection on the program due to the defects liability period. Don't want anyone stuffing around with my program and blowing up a $1 million engine then changing the program back and I get the blame for it. NOT ON!!!! My insurance comany would love me for that. Insurance is expensive enough now. After 12 months and a day has passed, the client is quite welcome to the password as defects liability has passed. I do not have any proprietary type code generally, but I can understand integrators protecting code from theft that they have spent many hours developing. And believe me, theft of code occurs regularly despite copywrite protection which is as useless as tits on a bull. With the advent and further development of function blocks, it is now becoming possible to password protect only a function block. This means that proprietary code inside that function block can be protected and the rest of the program left clear for "factory fiddlers". However, I will continue to password protect any software I write until the end of the defects liability period. The customer is then free to have the password and blow up all the $1 million engines he wants to. I might add that if the code is written and commissioned properly, there should be no need to alter it. Whenever I get called out to a service call on any of the systems I implement, everyone expects me to plug in the laptop. I DO NOT!!! The first thing I do is pull out the drawings and check inputs and outputs by way of the LED indicators on the I/O cards. About 90% of the time I do not even have to open the laptop. The LEDs are usually the telling blow for trouble shooting, not the code itself. I might add that I do a site where access was required all the time. I made them sign a legally binding contract to cover myself.

Have fun cracking a CS1 or CJ1. Limited number of tries and then YOU ARE LOCKED OUT FOREVER!!! Throw the processor away and start again. Good luck!!!!

No!!! Have a couple of hundred installed with no problems.

Here is a working SFTR function from a scaled analogue input. Sorry it is s bit rough and not commented but it was written on the fly when the client changed his mind but it does work. RAAFGlenbrook.pdf

Power the remotes up first and see if this helps. If the battery is 5 years old, replace it.

Here is a link for an easy scaling method Scaling CJ1 CS1 What resolution is your input and output? This will make a difference. If you write numbers to the output as a % of the output value is the output voltage correct?

I really cannot see any difference although I have not used a sattelite modem before. Is there some difference in the way the modem is set up?

It does if the swich is set to NT Link and you want to communicate with Host Link.
