Structure of a PROFIBUS DP network
The figure below illustrates a typical PROFIBUS DP network structure. The DP masters are
integrated into the respective device. The CPU, e.g. a CPU 410-5H Process Automation, has
an integrated PROFIBUS DP interface (DP master). The ET 200PA SMART is a DP slave that
is connected to the CPU via PROFIBUS DP. .

1.3 ET 200PA SMART Distributed I/O device
Definition
The ET 200PA SMART Distributed I/O device is a modular I/O device with IP20 degree of
protection.
ET 200PA SMART has the technical setup of the S7-300 automation system and is made up
of the IM 650 interface module and special ET 200PA SMART I/O modules.
Besides the ET 200PA SMART I/O modules, operation of standard I/O modules, HART analog
modules and special FM and CP modules from the S7-300 series of modules is also possible
in an ET 200PA SMART, provided these modules are approved for use in PCS 7.
You configure an ET 200PA SMART with a mounting rail and corresponding active bus
modules.
ET 200PA SMART can only communicate with a DP master of an S7-400 PA CPU:
● CPU 410-5H as of firmware version 8.1
● CPU 410 SMART as of firmware version 8.1
You can configure an ET 200PA SMART station only in conjunction with PCS7 V8.1 or higher.
