PROFIBUS DP

5.1

CPU 410-5H as PROFIBUS DP master

Startup of the DP master system
You use the following parameters to set startup monitoring of the DP master:
● Ready message from module
● Transfer of parameters to modules
This means that the DP slaves must be started up and their parameters assigned by the
CPU (as DP master) within the set time.
PROFIBUS address of the DP master
PROFIBUS addresses 0 to 126 are permissible.
Output and input data length
The maximum output or input data length you can use for each DP station is 244 bytes.
For an ET 200PA SMART, the maximum output or input data length you can use is 242
bytes.
For each ET 200PA SMART you are using in a DP line, the total number of user data of this
DP line is reduced by one output word and one input word.

DP address ranges of the CPU 410-5H

Address ranges of the CPU 410-5H
Table 5- 1
DP interface as PROFIBUS DP, both inputs and outputs (bytes)
Inputs and outputs up to x bytes each can be set in the process image
In the address range for the inputs, each DP diagnostic address occupies at least 1 byte for
the DP master and each DP slave. You specify the DP diagnostic addresses when
configuring. If you do not specify DP diagnostic addresses, STEP 7 assigns the addresses
as DP diagnostic addresses in descending order starting at the highest byte address.
