Profile files and MIB compilers
The range of information that can be monitored by the devices with the SIMATIC NET SNMP
OPC server depends on the particular device profile.
With the integrated MIB compiler of STEP 7/NCM PC, existing profiles can be modified and
new device profiles created for any SNMP-compliant device. It requires MIB files according
to the SMIv1 standard.
The SMIv1 MIB of the CP and a complete device profile are available on the supplied
product CD or can be downloaded from Support:
MIB (http://support.automation.siemens.com/WW/view/en/22414405
