Can I use the RS232 port as RS485? Or do you mean I can runt Modbus on RS232 on the HL?
In the mapper I can only choose RTU(RS485)/TCP, no choice for RS232.
Hi,
You can run both RS485 and TCP at the same time.
For a simple usage, you can create the modbus profile of your UPS, import it and then use it in the modbus tab, then just choose TCP, give the IP, and perform the mapping. the homelynk will handle everything else.
The other possibility is to create a script and use modbus TCP connection.
but this is more complicated and I would recommend to go with the profile.
Modbus is either RS-485 or TCP, but no RS-232.
As far as I know, you cannot connect a modbus RS-485 device on a RS-232 port.
Can you give the reference of you UPS or a technical document?
