Hello m. azzeh: A Profinet network uses a controller-device connection for data exchange between an IO Controller (for example your S7-1200 PLC) and one or more IO device, such as your VFDs and your ET 200 remote I/O stations. The IO controller acts as a master and initiates all coommunication on the network, the IO devicess act as slaves on the network and reply to read and write requests from the controller. Submodules are the data exchange structure that an IO Device will send and receive from the IO controller.If you open the configuration of your ET 200 station (by the way, which family are they, ET 200M, ET 200S, ET 200SP, ET 200MP...?), you will see various I/O modules in the rack . The I/O areas are each a submodule for this IO Device. Your VFD's configuration might show more than a telegram, each one is a submodule for the data exchanges with the IO Controller. The following Profinet Functions manual should provide you with the basic information you need to setup and configure your Profinet stations: https://support.industry.siemens.com/cs/ww/en/view/49948856/86379029643 Daniel Chartier |
