Process Data Block Descriptions
1.3. Process Data Block Descriptions
This subsection discusses the following:
• 1.3.1. Input Process Data Block Description
• 1.3.2. Output Process Data Block Description on Page 15
1.3.1. Input Process Data Block Description
The Input Process Data Block format is dependent on the configured PDI Data Format. The following tables
describe the Input Process Data Block in the possible formats.
Parameter Name Data Type Description
Port Status BYTE
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):
0= No fault detected
1= Fault detected
• A minor communication fault is indicated by the Operational
status bit being set to 1. A minor communication fault results
from:
- A temporary loss of communication to the IO-Link device.
- A recoverable IO-Link Master 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 IO-Link Master software or hardware
fault.
Bits 4-7: Reserved (0)
Auxiliary I/O BYTE
Auxiliary I/O:
Bit 0: The status of the Pin 2 auxiliary bit.
0 = off
1 = on
Bits 1-7: Reserved (0)
Event Code INT 16-bit event code received from the IO-Link device.
PDI Data
Default Length = 32
bytes
Array of up
to 32
BYTEs
The PDI data as 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.
