Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
I have found a very interesting solution using: IoConfigTaskMap IoConfigConnectorMap IoConfigChannelMap The first is the list of IO tasks. The second is the connector for each IO module in the IOMap. The third is the individual input or output on the IOMap. One of the properties of the connector is another pointer to a connector, which corresponds with the connector of the EtherCAT slave. Through this information, it is possible to understand to which EtherCAT slave an IO connectormap corresponds. I am attaching an FB that allows for the construction of an IO map and finding the pointer to the actual IOs in the IOMap based on the bitoffset.
