RX Logix 5000 plc with ASCII communication

Hi Friends,

We are planning to use 1769-L3 PLC with ASCII module as we are planning to communicate with Microcontroller , Barcode reader and Universal Temperature indicator. In 1769 PLC how many ASCII modules can be used? Pl. help me out as i want desired hardware configuration.

I don't see why you can't have at least two. Keep in mind that Port 0 on the PLC itself is an ASCII port itself.

We use it to send out print strings to our Wasp printers.
