Basic procedure for creating a PROFIBUS DP system
● Configuration
– Creating PROFIBUS devices and modules in STEP 7
– Assigning the DP slave to a DP master (Page 43)
● Optional: Parameter assignment
– Assigning the PROFIBUS address (Page 45)
– Making network settings (Page 46)
– Considering cable configuration (Page 49)
– Considering additional network devices (Page 51)
– Bus parameters – creating a user-defined profile (Page 52)
– Configuring constant bus cycle time (Page 55)
3.1
Assigning the DP slave to a DP master
PROFIBUS DP system
A PROFIBUS DP system consists of a PROFIBUS DP master and its assigned
PROFIBUS DP slaves. Once the devices have been placed in the network view or device
view, STEP 7 assigns default parameter values to them. Initially, you only have to assign the
DP slaves to one DP master.
Requirement
● The network view of STEP 7 is open.
● A CPU has been placed (e.g., CPU 1516-3 PN/DP).
● A DP slave has been placed (e.g., IM151-1 HF).
