Components
Function
1
Mounting rail
The mounting rail is used to secure all the components of the
ET200pro system easily and allows the components to be connected
to each other efficiently and accurately.
2
Connection modules
for interface mod-
ules
The connection modules are mounted on the interface modules. The
modules are designed to allow a variety of connections types suitable
for a number of applications.
The follow connection modules are available:
•
Direct connection:
–
CM IM DP Direct
•
ECOFAST:
–
CM IM DP ECOFAST CU
–
CM IM DP M12, 7/8"

PROFIBUS DP
interface module
with bus module
The interface module interconnects the ET 200pro with the DP master
and prepares the data for the electronic modules.The unit is delivered
with the terminating module. The interface module is already mounted
on the bus module.The bus module is the mechanical and electrical
connection element between the various ET 200pro modules.The
terminating module terminates the ET 200pro.The following interface
modules are available for PROFIBUS DP:
•
IM154-1 DP
•
IM154-2 DP HF

Safety Local repair
switch module
(F-RSM) with bus
module
The F-RSM is used to trigger the safety functions of the converter
through the backplane bus; it switches off the power bus for the motor
starters and frequency converters. An F-RSM must always be plugged
in the system to the left of the frequency converter and can be con-
trolled only through local safe inputs (Safety Local function).
5
Converter with bus
module
The converter is connected to the higher-level controller by way of the
bus module and interface module; power and motor are connected
using prefabricated cables.
6
Terminating module The ET 200pro bus is terminated with the terminating module
