Sample Programming
This sample transfers EtherCAT communications packets to an SD Memory Card when an EtherCAT
slave error occurs. The file name is 'PacketFile.' The processing procedure is as follows:
1
The system-defined variable _EC_ErrSta (EtherCAT Error) is monitored and processing is
started if an error occurs.
2
The EC_StopMon instruction is used to stop execution of packet monitoring for EtherCAT com-
munications.
3
The EC_SaveMon instruction is used to save EtherCAT communications packet data to a file in
the system of the CPU Unit.
4
The EC_CopyMon instruction is used to copy that file to the SD Memory Card.
5
The EC_StartMon instruction is used to restart execution of packet monitoring for EtherCAT
communications.
