Use RS485 Main and Sub simultaneously as Master

Hello, I have two RS485 buses with slave devices connected to each bus. Will it be possible to use both RS485 Main and RS485 Sub buses simultaneously in master mode so that a client can query all devices connected to both buses? See attached sketch.

No problem — both the RS485 Main and RS485 Sub ports can be configured as Modbus Master simultaneously. If the slave devices on both buses are Temco products, they can be scanned and automatically recognized by the T3000 software. If they are third-party Modbus devices, they won’t appear in the T3000 scan list, but the T3 controller can still communicate with them directly using Modbus commands.
