Title: Serial communications
Post by: Garyhlucas on June 01, 2021, 05:44:45 PM

I want to use some sensors that have a UART serial output that transmits ASCII strings of data. Does this imply they would communicate with the serial port on a BRX? Would this also likely be multidrop such that multiple sensors could use one serial port? Haven?t done much serial stuff except connecting from PC to PLC over the years.

The port can be either RS232 or RS485. Assuming it is one of those, then yes. Multidrop requires RS485.

Bob,
That makes sense. I?ll have to investigate further.

Thanks
