Distributed IO Systems
Distributed Input/Output modules are often used in plants without central management and mechanical sequencing.
In local plants, after collecting all data from motor accessories, local boxes & field instruments panels, consisted of I/Q modules are made. These modules are intercommunicate with main PLC (CPU) through Profibus of Profinet lines. Depending on the distance or route fiber optic cable line can be occasionally used.
Generally, ET200M and ET200S, if I/Q modules are used, can get necessary redundancy through these modules.
In lime plants, petrochemical plants and similar plants, which need additional explosion resistant applications, ET200 modules with EX-PROOF attributes can be supplied.
In special machine production, outside type ET200 PRO equipment group can be used directly on the machine.
