Setting parameters for the MPI and PROFIBUS interfaces

Possible parameter settings for the MPI and PROFIBUS interfaces

The following parameter settings can be made for the MPI and PROFIBUS interfaces:

  • Automatic configuration: You can use automatic detection functions to find out whether a device is connected to the PG/PC interface over PROFIBUS or MPI.

  • Selecting a default configuration for PROFIBUS or MPI that can be adapted later.

Device- and network-related settings for MPI and PROFIBUS

You can set device- and network-related parameters for MPI and PROFIBUS interfaces. Device-related parameters are local settings for the interface. Network-related parameters, on the other hand, must match up on all devices.

MPI interface parameters you can modify

You can adapt the following default parameters for the MPI interface:

Device-related parameters

  • Is only master

  • Own address

  • Timeout

Network-related parameters

  • Highest address

  • Transmission rate

PROFIBUS interface parameters you can modify

You can adapt the following default parameters for the PROFIBUS interface:

Device-related parameters

  • Is only master

  • Own address

  • Timeout

Network-related parameters

  • Highest address

  • Transmission rate

  • Profile

  • Bus parameters

  • Number of masters on bus

  • Number of slaves on bus

Note

Behavior when a subnet is assigned

If you permanently assign a subnet from the project to the interface, the subnet settings of the project take precedence. In this case, the settings for the respective interface cannot be changed.
