8.7 MODBUS SLAVE
8.7.1 Address and interface parameters
Addressing and configuration of the MODBUS Slave interface.
Via this interface the device can be networked with a master
building control system, the device then operates as a pure Slave
and uses the MODBUS-RTU protocol.
The connection is made to the terminals “A (D+)”, “B (D-)” of the
MODBUS Slave interface (see installation / RS-485 interfaces for
MODBUS RTU).
