The Industrial Raspberry Pi Forum

I need to communicate with an RS-232 device from a RevPi. I know that the gateway exists (https://www.kunbus.com/serial-rx-gateway-module.html), but I'm wondering if it's possible to use the RS-485 port on the RevPi along with something like this converter (https://www.serialcomm.com/serial_rs232 ... _info.aspx) to establish that connection.

Hi bsnyder, what about this: USB 2.0 to RS232 adapter, for DIN rail RS Components Article Nr. 745-6731

Hello,

I need to read 2 devices sending data from RS232. what is the proper way to do it? Does the mentioned device can read 2 Rs232 ports? Is there a specific module that can hadle this job?

Hi Ivan,

the linked USB to serial adapter supports up to two RS232 connections, so you should be fine with your use case.

Can you share an information how exactly to read this unit with USB from Codesys ?
I alo investigate the possibility to read trough LAN - https://www.wiznet.io/product-item/wiz750sr-110/
