Modbus Master Hardware and Physical Connections
The Modbus master functionality is built into the T9110 Processor Module; the
physical communication ports are located on the T9100 Processor Base Unit. You do
not need to add any extra hardware to the AADvance controller except to make the
physical connections to the processor base unit. The illustration shows some possible
arrangements of Modbus master connections.
The Modbus RTU slave devices are connected to one or more of the serial ports on
the controller; a typical arrangement will use a multi-drop (RS-485) arrangement. The
engineering workstation and the Modbus TCP devices are shown connected to the
Ethernet ports on separate networks; alternatively these can be combined onto one
network.
The OPC Portal Server
The OPC Portal Server is a windows-based application that allows OPC compatible
clients, such as HMIs and SCADA systems, to connect to one or more AADvance
controllers to access process data.
