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.

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. For example, the DP standard diagnostics for each node
can be called at these addresses using the LADDR parameter of SFC 13. 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.
