Command 0x30 – set fail-safe data pattern
23464
The command sets the behaviour of the outputs when the EtherNet/IP connection and the
corresponding fail-safe values are interrupted.
Corresponding parameter: [Fail-safe Mode] (→ Port configuration (→ p. 70))
The number of the required fail-safe values results from the size of the output data (→ Process
data length (→ p. 69)).
