What is the ET 200S distributed I/O system?

Definition
The ET 200S distributed I/O system is a highly modular, extremely flexible
DP slave I/O device with IP20 degree of protection.
Area of application
You can connect virtually any number of I/O modules in virtually any combination
right next to the interface module that transfers the data to the DP master and I/O
controller. This means you can adjust the configuration to suit local requirements.
Depending on the interface module, each ET 200S can consist of up to 63
modules -- for example, power modules, I/O modules, and motor starters.
The fact that motor starters can be integrated (switching and protecting any
three-phase load up to 7.5 kW) ensures that the ET 200S can be quickly adapted
to suit virtually any process-related use of your machine.
The fail-safe modules of the ET 200S ensure the fail-safe reading and output of
data to safety category 4 (EN 954-1)
Terminal modules and electronic modules
The ET 200S distributed I/O system is
• connected to PROFIBUS DP at the IM151 interface module by a plug
connector for PROFIBUS DP
• connected to PROFINET IO at the IM151-3 PN interface module by a plug
connector for PROFINET IO
Every ET 200S distributed I/O system is
• a DP slave on the PROFIBUS DP or
• an I/O device on the PROFINET IO.
