Configuring the process data
Manual modification of the process data
According to the ESI description, a PDO can be identified as “fixed” with the flag “F” in the PDO
overview (Fig.
“Configuring the process data”
, J). The configuration of such PDOs cannot be
changed, even if TwinCAT offers the associated dialog (“Edit”). In particular, CoE content cannot be
displayed as cyclic process data.This generally also applies in cases where a device supports
download of the PDO configuration, “G”.In case of incorrect configuration the EtherCAT slave usu-
ally refuses to start and change to OP state. The System Manager displays an “invalid SM cfg” log-
ger message:This error message (“invalid SM IN cfg” or “invalid SM OUT cfg”) also indicates the
reason for the failed start.
