TB_ECT_Diagnosis
This function block provides an EtherCAT diagnostic functionality for a PLC project. The fb checks the EtherCAT-Master, the EtherCAT-Kernle and for all EtherCAT-Slave. The internal mapping for the EtherCAT-slaves is done by the Node-ID. The fb checks during his initialization the EtherCAT-Master Firmware and the used EtherCAT-kernel version. The dataset-ID of the actual EtherCAT configuration can be checked optional during the initialization.
The clear text error messages are deposited in english language.
For the function block it's necessary to connect him with the interface to the EtherCAT-Master, EtherCAT-Slave and the EtherCAT-Kernel. This must be done by global defined input and output parameters which are connected to the fb.
The block is compatible up to EtherCAT master firmware 1427.0127.
Limitations:
- The EtherCAT diagnosis option is available from EtherCAT master firmware 1427.0114 and EtherCAT kernel version > 100
- The current number of slaves is internally limited to 256!
