Hello,

I’m using CODESYS EtherCAT Master on a Raspberry Pi controller with several remote I/O modules.
I’m facing an issue where the input values from the remote I/Os drop to 0 when a connection error occurs.

Is there a way to configure a β€œkeep last value” behavior (i.e., hold the last valid input) instead of defaulting to 0 on communication loss?

Best regards,
