SIMATIC ET 200 System Benefits -
Installation and Engineering
Easy mounting
Integral plug connections make installation quick and easy and therefore
reduce the costs. In the case of modular systems, mounting is on a rail. The
modules are snapped onto the rail and plugged into each other. The backplane
bus is assembled automatically. The sensors and actuators can be easily
connected to a bus system without the need to use an array of single wires
with cable distributors and cable racks. This makes the wiring simple and
transparent, less error-prone and therefore low-cost.
Permanent wiring
Due to the separation of mechanics and electronics, permanent wiring is
possible, i.e. the station can be prewired before installation or start-up.
Prewiring can therefore be inspected without the electronics modules which
prevents damage to sensitive components. The start-up time is therefore
reduced. The modules can also be replaced in the event of a fault without
time-consuming rewiring
Consistent Engineering
The ET 200 systems can be integrated into the SIMATIC controller with
minimal engineering outlay. The widely implemented standard tool STEP 7 is
used for engineering and diagnostics. The distributed I/O is configured in
the same manner as the central I/O. Engineering can be performed from any
point in the system - locally in the plant or centrally in the engineering
station. If the ET 200 is connected to a non-Siemens PLC over PROFIBUS or
PROFINET, the supplied device master file is used. This file contains the
configuration and parameterization data in standardized form and is used in
the configuration tool of the non-Siemens master.
