Connecting to old PLCs throw serial

[blima]

Hi!

I have several PLC's that need serial port to communicate with. I have tried with the USB serial cable and it will not work!

I found on eBay the following hub:

I think it will work, since I suppose that it is 12V power driven inside. Does anyone have worked with this one? Or a similar hub that will work?

Thanks,
Bruno

Which USB-to-Serial converter will work depends a lot on the brand and model of the PLC.

It will be OMRON and ABB

Buy the Omron USB/serial converter and save yourself a lot of grief. It is expensive but has been tested and works with all Omron PLCs - and anything else I have ever tried.
Failing that if you will not pay the money I would make sure the converter has an FTDI chipset inside - they appear to be far more reliable and connect to more devices than any other I have ever tried. The Omron one has an FTDI chipset.

I've never had a problem using the Keyspan USB/Serial converter.
I've had nothing but problems using any other.

Thanks for the replies

I will try to but the cable from OMRON

And regarding the old PLC's from ABB? Will the keyspan do the job?

Thanks,

I believe you will find the Omron one will do the job - I have never had a fail to connect or any dropping out with mine to anything.

Thank you!

I will go for the omron then.

Hello again!

I have found a printed copy of the ABB PLC program. But I woul like to confirm if it is the same that is on the machine!

Does anyone have the ABB 907 PC32 software?

I have search it but did not find it.

Thanks,
Bruno
