Read ISDU
With Read_ISDU, parameters of a connected IO-Link device can be read.
Request
CIP Attributes determines the IO-Link port to which the IO-Link device is connected. The area "CIP
User Specific Service Data" contains the IO-Link index and the IO-Link sub-index of the IO-Link object
whose value is to be read:
CIP Format Data type MSG Config Description
CIP Class ID UINT 0x80 IO-Link acyclic access
CIP Instance ID UINT 0x01 IO-Link master
CIP attributes USINT 0x01…0x08 Port number
CIP Service Code ID USINT 0x4B “Read ISDU” service
CIP User Specific Service Data UINT 0x0000…0xFFFF ISDU object index
USINT 0x00…0xFF ISDU object subindex
Response
Fault-free processing
If the service has been executed successfully (CIP Error Code = 0), the read data are returned bit by
bit (CIP User Specific Service Data). The response has the following format:
CIP Format Data type MSG Config Description
CIP Class ID UINT 0x80 IO-Link acyclic access
CIP Instance ID UINT 0x01 IO-Link master
CIP attributes USINT 0x01…0x08 Port number
CIP Service Code ID USINT 0x4B “Read ISDU” service
CIP Error Code USINT 0x00 Fault-free processing
CIP Extended Error Code USINT 0x00 --
CIP User Specific Service Data USINT 0x00…0xFF Data (byte 0)
USINT 0x00…0xFF Data (byte 1)
… … …
USINT 0x00…0xFF Data (byte n)
The read data is in the IO-Link format. If necessary, the user needs to adapt the byte
arrangement of the read data to the CIP format.
Fault
If an error occurs while executing the service (CIP Error Code <> 0), an extended error code will be
transmitted (CIP Extended Error Code). If the CIP Error Code = 0x1E, the CIP Extended Error Code is
= 0x00 and the IO-Link Error Code and the IO-Link Additional Code will be transmitted in the CIP User
Specific Service Data area. The response has the following format:
CIP Format Data type MSG Config Description
CIP Class ID UINT 0x80 IO-Link acyclic access
CIP Instance ID UINT 0x01 IO-Link master
CIP attributes USINT 0x01…0x08 Port number
CIP Service Code ID USINT 0x4B “Read ISDU” service
CIP Error Code USINT <> 0x00 Error code (see below)
CIP Extended Error Code USINT 0x00 Extended error code
CIP User Specific Service Data USINT <> 0x00
IO-Link Error Code: Error Code (Ò/102)
