DF1 to RS485

[Aurelien]

Hi,

I use a T7A and I would to know how do I create a DF1 port ?

Com 1 = Com 3 = RS 232

Com 2 = Com 4 = RS 422 / RS 485

I would communicate from T7A to PLC with 1747 uic.

I need to use USB port but I don't know how do it.

Best regards

Hi Aurelien,
The way to access the DF1 Port on an Allen bradley PLC is by using the 232 port and the Allen Bradley DF1 Driver. An FTDI USB to serial adapter can be used on some HMIs to add another Serial COM port to the panel.
