Functionality Descriptions
Functionality Descriptions
Data
Description
Type
The status of the IO-Link device.
Bit 0 (0x01):
0 = IO-Link port communication initialization process is inactive 1 = IO-Link
port communication initialization process is active
Bit 1 (0x02):
0 = IO-Link port communication is not operational 1 = IO-Link port
communication is operational
Bit 2 (0x04):
0 = IO-Link input process data is not valid. 1 = IO-Link input process data is
valid.
Bit 3 (0x08):
BYTE
0= No fault detected 1= Fault detected
A minor communication fault is indicated by the Operational status bit is
set to 1. A minor communication fault results from:
-
A temporary loss of communication to the IO-Link device.
-
A recoverable IOLM software or hardware fault.
A major communication fault is indicated by the Operational bit being set
to 0.
-
An unrecoverable loss of communication to the IO-Link device.
-
An unrecoverable IOLM software or hardware fault.
Bits 4-7: Reserved (0)
