DIRIS Digiware D-50 & D-70 - 548088B - SOCOMEC
For example the OID for instCurrentI1 is represented by the sequence 1.3.6.1.4.1.4555.10.20.20.1.10000.
OID SEQUENCE DESCRIPTION
4555 “SOCOMEC” enterprise branch
10 “SocomecProducts” table
20 “ProductMetrology” table
20 “InstantaneousTable”
1 Entry (always = 1)
10000 Service ID
This OID is associated with the multiple devices connected downstream the DIRIS Digiware D-50 / D-70.
To identify those multiple devices, the Modbus address and the load number are added to the end of the OID.
Example: Let us consider the following architecture:
PRODUCT I-30 I-30
MODBUS ADDRESS 4 5
LOAD TYPE Load 1: 3P + N - 3CT
Load 1: 1P + N - 1CT
Load 2: 1P + N - 1CT
Load 3: 1P + N - 1CT
U-30
@3
I-30
@4
I-30
@5
D-50/D-70
Digiware bus
The nal OID to get the instantaneous current I1 for the I-30 module @ Modbus address 4 for load 1 is:
1.3.6.1.4.1.4555.10.20.20.1.10000.4.1
For the I-30 module @ address 5, there are multiple loads congured. This implies that the Modbus address must be
followed by the Load number in the OID.
Therefore, the nal OID used to request I1 Inst for load 1 of the I-30 @ address 5 is:
1.3.6.1.4.1.4555.10.20.20.1.10000.5.1
The nal OID to request I1 Inst for load 2 of the I-30 @ address 5 is 1.3.6.1.4.1.4555.10.20.20.1.10000.5.2
The nal OID to request I1 Inst for load 3 of the I-30 @ address 5 is 1.3.6.1.4.1.4555.10.20.20.1.10000.5.3
OID SEQUENCE DESCRIPTION
4555 “SOCOMEC” enterprise branch
10 “SocomecProducts” table

5 Modbus Address
3 Load number
Note: a request to OID 1.3.6.1.4.1.4555.10.20. 20.1.10001.5 will return “0” because the service ID 10001
corresponds to I2 inst whereas only single-phase loads are congured in the I-30 module @ address 5, which
means currents I2 and I3 parameters aren’t used.
