MIB
To retrieve data from the device using the SNMP object identifier (OID), the MIB files from the
NET-SNMP package should be copied to the correct location on the client station.
The NET-SNMP package can be downloaded from the link:
https://sourceforge.net/projects/net-snmp/files/net-snmp/5.7.3/
In the downloaded zip package, MIB files are available in directory: net-snmp-5.7.3.zip\
net-snmp-5.7.3\mibs\
The objects used in CMS-700 are defined in SNMPv2-MIB.txt and NET-SNMP-EXTEND- MIB.txt.
The list of available objects is shown in Table 1.
All objects are read-only. In case of a NET-SNMP-EXTEND::nsExtendOutputFull object, the var field is
one of variables defined in table Modbus and SNMP Mapping, for example:
NET-SNMP-EXTEND::nsExtendOutputFull."TRMSsens1".
To return all TRMSsens values in a single snmpget request, please use the "TRMSsensAll" variable name.
