5. TYPES In 2000 Bronkhorst developed their first digital instruments according to the multibus principle The basic pc board on the instrument contained all of the general functions needed for measurement and control including alarm totalizing and diagnostic functions It had analog O signals and also an RS232 connection as a standard feature In addition to this there is the possibility of integrating an interface board with DeviceNet Profibus DP Modbus FLOW BUS or EtherCAT protocol The first generation MBC I was based on a 16 bit Fujitsu controller It was superseded in 2003 by the Multibus type 2 MBC II This version was also based on the 16 bit Fujitsu controller but it had several improvements to the MBC I One of them is the current steering of the valve It reduced heat production and improved control characteristics The latest version Multibus controller type 3 MBC3 is introduced in 2011 It is build around a 72MHz 32 bit NXP ARM controller It has AD and DA controllers on board which makes it possible to measure noise free and control valves without delays The internal control loop runs 6 times faster compared to the MBC II therefore control stability has improved significantly It also has several improved functions like reverse voltage protection inrush current limitation and overvoltage protection MBC3 instruments can be recognised by the MBC3 placed on lower left side AML I A of the instrument l
