FUNCTION_BLOCK Generic_Service EXTENDS BaseService
This function block performs a generic service at an EtherNet/IP Adapter. The message will be sent as an unconnected explicit message request.
Note
Data received and send needs to be swapped. See parent folder.
/// Force trigger to TRUE to activate.
/// Example device used here is WAGO 750-352 FC ETHERNET.
/// But you can adapt it, by using the services which are implemented by your prefered device.
