Writing Modbus data from SNMP
:
In order to write the data to the converter
it is necessary to use the “snmpset” command. The Output
array is contained to
this internal directory: 1.3.6.1.4.1.33118.1.1.1.4.x.0, where ‘x’ is the number of data
block. Each data block has a dimension of 128 bytes.
Example: you want to write information
of the data block 3 with the data ‘0123456789’ (ASCII). The
structure of the command to send is:
snmpset
–v1 –cprivate “IP Address of the converter” 1.3.6.1.4.1.33118.1.1.1.5.
