PROFINET Commander is one of many PROFINET tools available, targeted towards users interested in interacting with PROFINET devices. Automation product developers can test quickly a new device or system under development. Meanwhile, vendor salespeople can demonstrate a product without additional hardware. End-user engineers can configure a device to check before employing in production. End-user maintenance persons can set up a device name or get diagnostics via PROFINET.

The main features are:

  • I/O controller and I/O checking
  • Diagnostics
  • Reading and writing PROFINET data records
  • DCP browser

I/O Controller

The I/O controller in PROFINET Commander can be used to communicate to an I/O device or network consisting of multiple devices. This is a vendor-independent function, works with any PROFINET RT device. Users can start and stop the device(s), set I/O points, and get diagnostic alarms.


The Diagnostics functions can be used to troubleshoot a device in the event of a real-time diagnostic alarm. There are both alarm functions and multiple ways to read the diagnostics out of the device directly in the event of a diagnostic condition. Diagnostics can also be read acyclically by using data records.

Reading and Writing

PROFINET read and write functions can be used for parameterization or any device specific information. This allows you to read standard PROFINET records like AR (Application Relation) information, I&M (Identification & Maintenance) information, port information, diagnostics and more. There is even the ability to write standard or vendor specific parameters to a device directly.

DCP Browser

The latest version of the software provides a DCP (Discovery and Configuration Protocol) browser that lets you scan the network for devices, setup device names, and IP addresses, and get manufacturer information or a network inventory.
