Omron & serial FINS

[Archie]

I still have no connection.

But as soon as I turn on the PC without starting any program I see the communication led, 1 flash per second, on the plc flash.
Connected osilloscope, I saw a signal coming from PC from com1

This sounds like something else is using the COM port which would not let AdvancedHMI get access to it.

I do not have other PCs with native serial port,
If I buy a usb-serial adapter to work?
It's strange this signal coming out of the com1 without any software started.
Or is it caused by jumpers 7-8 or 4-6 on com1?

On the AHMI panel I can set COM 12, the driver works for com ports?

Wowow, RESOLVED.
I found a service that occupied the com, an old SCADA software installed for trial.
I'm already reading the data on the Voltmeters.

Thanks for the support
