CPU (standard, fail-safe,
compact or technology
CPU)
The CPU executes the user program. The integrated system power
supply of the CPU supplies the modules used via the backplane bus.
Further features and functions of the CPU:
• Communication via Ethernet
• Communication via PROFIBUS/PROFINET
• HMI communication
• Integrated web server
• OPC UA server
• OPC UA client
• Integrated technology (e.g. motion control functions, trace func-
tionality)
• Integrated system diagnostics
• Integrated protection functions (access, know-how and copy pro-
tection)
• Safety mode (when using fail-safe CPUs)
Interface module for
PROFINET IO
The interface module:
• Is used as an IO device on PROFINET IO.
• Links the ET 200MP distributed I/O system with the IO controller.
• Exchanges data with the I/O modules via the backplane bus.
Interface module for
PROFIBUS DP
The interface module:
• Is used as a DP Device on PROFIBUS DP.
• Links the ET 200MP distributed I/O system with the DP master.
• Exchanges data with the I/O modules via the backplane bus.
I/O module/
fail-safe I/O module
The I/O modules form the interface between the controller and the
process. The controller detects the current process state via the con-
nected sensors and actuators, and triggers the corresponding reac-
tions. I/O modules are divided into the following module types:
• Digital input (DI, F-DI)
• Digital output (DQ, F-DQ)
• Digital input/digital output (DI/DQ)
• Analog input (AI)
• Analog output (AQ)
• Analog input/analog output (AI/AQ)
• Technology module (TM)
• Communication module (CM)
• Communication processor (CP)
A U connector is included in the scope of delivery for each I/O module.
For fail-safe I/O modules, an additional electronic coding element for
saving the PROFIsafe address is included in the scope of delivery and
can be ordered as spare part Accessories/spare parts (Page 363).
