Posted 12 March I would like to ask you more experienced people for advice and possible suggestions. I would need to ensure communication between two devices. The first device, it only handles communication via the MODBUS RTU (RS-485) protocol, this device should be a "slave". The second device ("master"), I assume some kind of PLC, communication via the PROFIBUS protocol. Do you have any types of converters for this format, or other solutions? Thank you.

Posted 12 March No personal endorsement, but I've seen other products from Anybus that seemed solid:https://www.anybus.com/products/gateway-index/anybus-xgateway/detail/anybus-x-gateway-profibus-master-modbus-rtu-slave Do you think that one might work? I checked ProSoft first but they only have Profibus to Modbus TCP, not RTU. Share this post Link to post Share on other sites

OP wants to connect a Modbus RTU Slave to a Profibus Master Share this post Link to post Share on other sites
