2 Instruction Descriptions
Function
The GetECError instruction gets the highest level status and highest level event code of the current
communications port errors or master errors in the EtherCAT Master Function Module and outputs
them to Level and Code. If there are currently no communications port errors or master errors, the value
of error flag Out is FALSE. If there is more than one Controller error at the highest event level, the value
of Code is the event code for the Controller error that occurred first.
The following figure shows a programming example.
