Communication PROFIBUS(master) + MODBUS(slave)

[Jirikk 0]

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.

No personal endorsement, but I've seen other products from Anybus that seemed solid:

Do you think that one might work? I checked ProSoft first but they only have Profibus to Modbus TCP, not RTU.

Wrong Anybus.  This one, I think:

Isn't that for a Profibus slave? OP wants to connect a Modbus RTU Slave to a Profibus Master

No, it IS a Profibus slave.  Because the OP HAS the master.  And IS a Modbus master, because the OP HAS the slave.

Well, there I go not spending enough time reading the details...
