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.
69 ))
The number of the required fail-safe values results from the size of the output data (
→
Process
data length
(
→ p.
68 )).

Legend:
Port no. (LSB) Number of the IO-Link port (low byte)
Port no. = 0xXX YY

Port no. (LSB) = 0x YY
8 bits 0x01 = port X01
0x02 = port X02

0x04 = port X04
Port no. (MSB) Number of the IO-Link port (high byte)
Port no. = 0x XX YY

Port no. (MSB) = 0x XX

Fail-safe mode Behaviour of the outputs when the
EtherNet/IP connection is interrupted
and setting of the corresponding
fail-safe values 8 bits 0x00 = No Fail-safe
0x01 = Fail-safe Reset Value
0x02 = Fail-safe Old Value
0x03 = Fail-safe with Pattern

Byte Length N Number of the bytes that contain
fail-safe values 8 bits 0x00 = 0 bytes
