Important information

The flow converter with the RS485 interface card fitted, is able to communicate with an external
device (PC or other suitable computer system) using the Modbus protocol. This option allows
data exchange between PC or computer and single or multiple devices.

The bus configuration consists of one external device as a master and one or more converters as
slaves. For bus operation the device address (menu C6.8.1), baudrate (menu C6.8.2) and settings
(menu C6.8.3, C6.8.4, C6.8.5 & C6.8.6) must be set in the converter.

All devices connected to the bus, must have different unique addresses but the same baud rate
and settings.
