Identification \ and Maintenance Functions

The so called “Identification & Maintenance Functions” in PROFINET® realize the reading of device specific information, e. g. serial number and order number. This information can be queried for every PROFINET® IO Device by means of the PNIO_IM0 Function Block.

Note

The IO Devices CI501-PNIO and CI502-PNIO supports exclusively I&M 0 function.

The I&M 0 function contains following information:

• VendorID (WORD)
• OrderID (STRING:20)
• SerialNr (STRING:16)
• HW-Revision (WORD)
• SW-Revision (1 CHAR plus 3 x BYTE, e. g. V.1.2.3)
• RevisionCounter (WORD)
• ProfileID (WORD)
• IM_ProfileSpecType (WORD)
• IM_Version (2 x BYTE)
• IM_supported (WORD)

The structure and the meaning of these information is specified in the PNO “Profile Guidelines Part 1: Identification & Maintenance Functions” (version 1.1.1, order number 3.502).
