Description
Auxiliary I/O
BYTE
The auxiliary bit on the IO-Link port is:
Pin 2 on the IOLM
Bit 0 (0x01): The status of the auxiliary bit.
0 = off
1 = on
Bits 1-3: Reserved (0)
If Include Digital I/O in PDI Data Block is disabled:
Bits 4-7: Reserved (0)
Bit 4 (0x10) – D1 = DI status Bit 5 (0x20) – D2 = DIO status
Bit 6 (0x40) – D3 = D2 status Bit 7 (0x80) – D4 = DIO status
Event Code
INT
16-bit event code received from the IO-Link device.
PDI Data
Default Length = 32
bytes
An array of
up to 32
BYTEs
The PDI data was received from the IO-Link device. May
contain from 0 to 32 bytes of PDI data. The definition of
the PDI data is device-dependent.
Note: Length is configurable using the web page interface.
