Distributed inputs/outputs
The decentralization of inputs/outputs enables the requirements of both users and machine manufacturers to be met while obtaining performance comparable with that of a centralized architecture:
-
the volume of wiring connected to sensors and preactuators is reduced,
-
mechanical constraints associated with wiring ducts are eliminated,
-
time required for designing and testing connections is reduced,
-
machine or plant availability is maximized,
-
installations are more flexible and open to expansion,
-
PLCs can be operated more rationally.
distributed input/output modules provide the following:
-
a high level of adaptability: they may be mounted in any position, on any type of support (mounting plate, frame, DIN rail for TBX IP20s, etc.), in all industrial environments,
-
the interface elements take up less space,
-
easy to set up and connect: sensors and preactuators are directly connected to screw terminals (eliminating the need for intermediate terminal blocks), integral commons, several marking levels (operational, electrical, for identifying modules and connection points, etc.),
-
connection close to the sensors and preactuators in a harsh environment using TBX IP65,
-
A high level of modularity in order to adapt to the number and type of sensors and preactuators in a cell: input modules, output modules, mixed input/output modules and modules with programmable channels,
-
local management of operating modes and diagnostics, of connection points and connected channels,
-
conformity with international standards.
TBX distributed input/output modules are connected to the processor via the fieldbus, which provides 126 connection points for TBX modules.
