SIMATIC ET 200 System Benefits -
Increased availability
Hot Swapping
In the event of a fault, electronic modules are easily replaced during operation with the equipment live (hot swapping). The station remains functional, and the plant therefore remains available - there is no need for costly shutting down and starting up of the plant. While the components are being replaced, the wiring remains intact. Coding of the modules prevents mistakes when replacing them.
Redundancy
To increase plant availability, the SIMATIC system offers a system- wide redundancy concept. ET 200 I/O devices are connected with two interface modules to the two PROFIBUS lines of a high-availability automation system. If the active system fails, the standby system takes over the functions immediately so that standstill can be avoided.
Configuration in Run (CiR)
Modifications or expansions are also required during operation of a plant (section), such as implementation of additional sensors or actuators, reparameterization of I/O modules (e.g. choosing of other interrupt limits). Possible applications are non-stop requirements, that is, in continuous processes that cannot be shut down or whose production cannot be interrupted: process plants or manufacturing plants with high restart costs. Changes to the hardware configuration in RUN are possible when distributed I/O is connected to the S7-400
Stations can be added and removed,
e.g. for configuring a new process line
I/O modules can be added and removed,
e.g. for implementing additional sensors
I/O modules can be reparameterized,
e.g. for replacement parts Hinzufügen und
