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 final 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 configured. This implies that the Modbus address must be
followed by the Load number in the OID.
Therefore, the final 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 final 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 final 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
20 “ProductMetrology” table
20 “InstantaneousTable”
1 Entry (always = 1)
10000 Service ID
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 configured in the I-30 module @ address 5, which
means currents I2 and I3 parameters aren’t used
.
