Program description
Transmission of exemplary filter coefficients via CoE access into the box module.
General settings
• The function block "FB_EcCoESdoWrite" requires the "Tc2_EtherCAT" library
• <AmsNetID> must show the local device EtherCAT NetID in inverted commas (e.g.
'168.57.1.1.5.1')
• <DeviceEtherCATAddress> must show the local device EtherCAT address of the EPP3504‑0023
box module (e.g., 1007)
