The Modbus adapter is an optional device for the Active Filters which enables the
connection of the PQF-Manager to a RS485 Modbus system. The controller is considered
as a slave unit in the Modbus network.
Refer to the 2GCS214013A0050 - RS485 adapter- User guide for more information on the
RS485 Modbus Adapter.
GREEN
Be careful that the RS485 MODBUS ADAPTER is the one with a text color
(3.3V power supply).
WHITE
The one with a text color is reserved for the old model (5V power supply).
That means: the new Modbus adapter is not compatible to the old PQF-Manager; and
the old Modbus adapter cannot be connected to the new PQF-Manager (with touch
screen).
