PrtN_DeviceInformation Definition
6.7.1. PrtN_DeviceInformation Definition
The IO-Link Master requests this information from the IO-Link device during the IO-Link device
initialization process. It is then made accessible via explicit messages. The example PLC program
automatically requests this information block when the device status transitions to active.
PrtN_ ISDUSingleRespData
ISDU
response
parameters
An alternative ISDU response format. Must be used
with PrtN_ISDUReqArray4Byte.
RepeatISDURequests BOOL
If enabled, instructs all subroutines to repeat any
ISDU requests upon completion. Intended for
testing purposes. May be enabled by end user.
Run BOOL
MainProgram only.
Allows the ProcessIoLinkPortN subroutine calls if
enabled (1).
Prevents the ProcessIoLinkPortN subroutine calls if
disabled (0).
Parameter Name Data Description

64 ASCII
characters Requested from ISDU data block index 19, contains the
Product ID description of the IO-Link device.
ProductText
64 ASCII
characters Requested from ISDU data block index 20, contains the
Product Text description of the IO-Link device.
SerialNum
16 ASCII
characters Requested from ISDU data block index 21, contains the
Vendor Specific Serial Number of the IO-Link device.
HardwareRev
64 ASCII
characters Requested from ISDU data block index 22, contains the
Hardware Revision of the IO-Link device.
FirmwareRev
64 ASCII
characters Requested from ISDU data block index 23, contains the

DevicePdiLength INT
Length of valid PDI data from IO-Link device or port (if
not in I/O Link mode).
DevicePdoLength INT
Length of valid PDO data that can accepted by the IO-
Link device or port (if not in I/O Link mode).
PdiBlockLength INT
The configured PDI data block length. This includes the
header bytes and any PDI data.
PdoBlockLength INT
The configured PDO data block length. This includes the
header bytes and any PDO data.
InputRxPdiOffset INT
Provides the index into the Class 1 I/O input data
received from the IO-Link Master. The index corresponds
to the configured PDI data format of the port on the IO-
Link Master. Used to automatically index into the input
data and retrieve the PDI data block.
