The control subsystem includes flexible

communication options to I/O and intelligent

field devices via system buses. HART as well as

PROFIBUS information, including configuration

and diagnostic information, is communicated

via the control network. This information is

available to system controllers and system

level applications such as asset optimization

and device management. The comprehensive

bus concept of the system controller allows

for the easy integration of HART, PROFIBUS,

Modbus RTU and TCP field devices as well as

of PROFIBUS and IEC 61850 electrical assets.

The MR Series functional capabilities are

summarized in figure 2.
