  • Page 9 These must never be used for any other functions as this can result in destruction of the device. Pin 2 and Pin 4 carry the data of the PROFIBUS communication. These must never be reversed otherwise the communicati- on is disrupted. Pin 5 is the shield that is not internally connected to the module.

    If fewer data than are available are requested, the module only returns data of the requested data quantity. The module does not check the specified data length for acyclic requests. If a greater data quantity than available is specified in PROFIBUS or PROFINET, the data cannot be accessed and the device retains the last valid data.

    Diagnostics signals The sera INTERFACE MODULE has two diagnostics messages that are output in the network-specific protocol (PROFIBUS / PRO- FINET). A present message is indicated by flashing once for a short time of the Module Status LED. The messages can be read in plain text using the diagnostics function of the Engineering tool.
