I have placed an answer elsewhere. The post did not mention Cimplicity. I always use Citect with excellent results. Have noy used Cimplicity with Omron. As I mentioned elswhere, why use Ethernet when you have Controller Link? With the Controller Link PCI card you address each PLC on an individual basis cutting out any overhead getting information into one PLC. Does not make sense to me to use Ethernet. I ALWAYS GO WITH CONTROLLER LINK, if any peer to peer communications are required as well as to a SCADA. Elsewhere you mentioned you were using "G" processors. A bit confusing as you say here they are "H" processors. With Citect, it installs FINS Gateway as an application. It can be found by checking in Windows "Programs" area, the same as any application. You can find the version number there. The service manager should also have installed in the Windows task bar. The FINS Gateway application can be aslo accessed there.

Have not seen one of these old dears for a few years.

I believe automatic allocation only works in local symbols - but have been rpoven wrong before. I find the "symbol base" a pain the the "A", quite frankly. Wish you could cahnge to I/O number based. Old timer, used to numbers.

Not that I know of. You have to buy it.

The power on light is not the run light. They are separate. Power on indicates just that. the run light indicates that the PLC is OK and is running the program.

Why not????

If you prefer the book print the pdf file like I do, when I need a printout.

True. Living in the CS world.

Buy an SCB. They are not expensive. You can get one with 1 x RS232 and 1 x RS422/485.

Pretty inexpensive and very powerfull - CX-Supervisor. Extremely powerfull with all the bells and whistles - Citect. Download it at www.citect.com.

If you are using CS1 or CJ1 they are very good, as good or better than anything else I have used. The higher end tyhe processor, the quicker they go. The CS1H and CJ1H are the same processor and they are bl**dy quick!!!

I had all sorts of problems with USB/232 converters until I bought the Omron one. Using XP on a HP laptop. Problems have now gone away, even with AB. Spend the money and buy the thing or buy a laptop with a real serial port. HP have some nice laptops on special in Ozz with real serial ports. Seems a lot of laptop manufacturers are learning the lesson that real serial ports are still needed.

If the error does not go away, I would suggest that the communications are not set up properly. If it does go away, there are settings you can implement in Citect to extend the time before this message appears. Search the Citect knowledge base. Also contact Citect, their support is excellent. The package is in support is it not??? Are you using Ethernet? I have not used Ethernet before with Omron. Do not like it. Or are you using serial? The #COM in the boxes suggests that communications have failed. Is it an old system or one you are setting up?

You have to buy it, or purchase an upgrade for a legal copy from your frendly Omron office, or distirbutor, the same as the rest of us.

Yep. I bought it. You will have to buy it too.

I have Syswin 3.4 running succesfully on my main machine with XP Pro SP2, 1 gig RAM and also on my laptop with XP Home and only 512 meg RAM. Have never had the rpoblem. Sounds like it might be a Windows problem. Do a Ctrl-Alt-Del and see what the processor and page memory are up to.

Have never seen the problem before.

Which version of CX-Programmer? Sounds like a printer driver problem. Do you have the latest driver for your printer?

V5.21 is quite old now but pretty stable. I have not uses Ethernet with Omron to Citect, always use Controller Link. Not an Ethernet fan. Is the error genuine? Are you really losing communications or is the alarm a false alarm? Are you using the OMFINS Driver or FINS Gateway proper? If OMFINS, I would suggest you contact Citect and get the FINS Gateway CD from them, provided the Citect licence is in support. If it is not in support, you are probably on your own apart from help here. The FINS Gateway CD is the latest method of connection. You would also require the latest Citect FINS driver. Once again, the licence needs to be in support. What operating system?

A common alarm. What communications method ar you using? Controller Link, serial? Controller Link I hope, serial is for the birds. Does the alarm go away after time? What version of Citect? Details please and I may be able to help. I go back a long way with Citect and was a beta tester for the FINS Gateway driver.

There are V720S manuals here. They are quite large so be patient. RFID Manuals

Usually better to use a transistor.

As it is serial, you should be able to set up the protocol to communicate with the device using CX-Protocol and an on board or rack mounted serial port (SCU or SCB). I use this for Modbus RTU all the time.

Is the PLC 24VDC powered? It sounds to me like there may be a 24VDC switch mode power supply pulling down.
