Command 0x30 – Set fail-safe data pattern
23464
The command sets the behaviour of the outputs when the Modbus connection and the corresponding
fail-safe values are interrupted.
Corresponding parameter: [Fail-safe Mode] (→ Mapping: port configuration (→ p. 74))
The number of the required fail-safe values results from the size of the output data
(→ Configuration Area (→ p. 73)).
