DataMan 370/470 v6.1.8 – PROFINET Class B

Upgrading a DataMan 370/470 reader to firmware version 6.1.8 or higher installs a new PROFINET stack, adding support for PROFINET Class B. While this adds new functions and capabilities, it is not a drop-in replacement for a DataMan reader running the Class A stack, which all previous versions of DataMan firmware supported. You need to update the hardware configuration in the TIA software.

If you add DM370/DM470 readers to an existing system that has other DataMan products, both GSD files need to be installed. Refer to the table for which GSD file to use with a given reader.

Firmware Version and DataMan Model	GSD File	Description
DM370/DM470 Firmware 6.1.7 or later	V2.34 (GSDML-V2.34-Cognex-DataManClassB-20191018.xml)	Supports Class B, uses the Port stack. The Class-B configurations are suffixed with CC-B, indicating that the configuration is Class B. Example: DataMan 470 CC-B.
All other DataMan	V2.31 (GSDML-V2.31-Cognex-DataMan-20170215.xml)	Uses the Siemens PROFINET stack.

SNMP (Simple Network Management Protocol) v2 is supported only when the V2.34 GSD file is used. PROFINET uses the topology technology to detect and identify devices on SNMP.

Supported MIBs:

• LLDP-MID

• LLDP-EXT-DOT3-MIB

• MIB-II

Writable OIDs:

• 1.3.6.1.2.1.1.4.0 (sysContact, defaults to “Someone <someone@somewhere.net>”)

• 1.3.6.1.2.1.1.5.0 (sysLocation, defaults to “somewhere”)
• 1.3.6.1.2.1.1.6.0 (sysName, defaults to “something”)

These OIDs are reset to the default settings after a factory reset. Other OIDs are also supported in the above MIBs but have read access only.
