Transfer role: set the data storage, buffering logic to adapt to the speed difference between the CPU and peripherals, the interface usually consists of some registers or RAM chips, if the chip is large enough can also achieve the transfer of bulk data. Coordination role: can coordinate the CPU and peripherals in the type of information and level differences between the two, such as level conversion drivers, digital / analogue or analogue / digital converters, etc.. Interface board is responsible for the input and output (I/O) function board, interface board by the I/O special devices, control software, connectors and other components, interface circuit to the host (board) on the signal into a peripheral can be recognized signal, some have power output function. Such as computer USB, 1394, VGA, DVI-D, HDMI interface is a digital signal interface, VGA, A/D, D / A, sound card is an analog, digital conversion interface. Interface circuit board simple only mechanical connectors, complex itself is a microcontroller system.

There are two types of connections between controllers and I/Os:
-Local I/O: using Modulebus (electrical/fiber optic) communication lines, with a maximum of 8* local I/O stations per controller;
-Remote I/O: remote I/O connection using Profibus DP fieldbus extension, supporting a maximum of 98 remote stations;
-Longest distance Cable 500m (500Kb/s)
-Multimode fiber 2KM (12Mb/s)
* Non-redundant for 8 local I/O stations
Redundant for 7 I/O stations
As an important component of the control network, the AC800M controller supports two modes of operation, redundant and non-redundant, and two modes of communication services, client/server. The client service enables communication between controllers and with the engineer station software. The OPC Server service also enables data communication with third party software and systems such as HMI.
The AC800M controller supports a variety of popular communication protocols including MasterBus 300, COMLI, Modbus, and Siemens 3964R, allowing easy communication with other controllers, automation systems, and field devices. external devices.
