SNMP free software to test V350 SNMP communication

[eca]

Hello,

I  am using a V350 PLC in a project that requires SNMP communication to monitor several variables and show traps from the V350. I have already programmed the PLC to use SNMP y I've  found a very simple DOS software that only receives traps  from my V350 PLC, but  I need to test monitoring variables by SNMP (using a MIB file).  I do not know any free SNMP monitoring software for PC (windows 7) that could be configured with a MIB file and test both monitoring and traps.

Does any one know some software?

Thanks!
