Efficient and easy-to-program serial bussystems connect separately located stations

The ABB Procontic field bus, ZB10, ex-changes process data with the other ABBProcontic systems.

The ABB Procontic T200 bus ZB20 is de.signed specially for data exchange betweenABB Procontic T200

stations, transportingparameters, and downloading programs.

Serial interfaces on the communication processor are also available for transfer ofprograms and signal

states to an operatingstation.

An ABB Procontic T200 control consists, in itssimplest form, of a module rack, a central unit,program

memory, an input module, an outputmodule, and a power supply unit.

Expansion module racks provide ample roomfor further input and output devices. 

Fourcentral units classified according to their ex-pandability and a series of pre-processors andinterface

equipment enable optimum adaptationof the ABB Procontic T200 to the respectivecontrol task. 

The T200 can be configured cen-trally (in the immediate vicinity) or decentrally.
