Appendix E – Modbus VERIS H8035/H8036 Emulation
The MD-BMS and MD-BMED Model Meters can be used as a direct replacements for
the Veris, Inc. H8035/H8036 series of networked power meters. This mirroring of the
Veris Modbus register assignments makes replacement with an MD-BMS or MD-
BMED Power Meter simple. However, because the number of parameters that the
Veris meters measure is less than half of what the MD-BMS or MD-BMED Model
Power Meter can measure, the other Modbus registers described in the table need to
be used to utilize the additional capabilities of the MD-BMS and MD-BMED Power
Meters.
Writing a 1 to register 44526 sets the Slave ID to Veris mode and ViewPoint lists the
Veris registers in the ViewPoint Read/Write Registers tab.
When register 44526 contains a 1 for Veris mode, the Slave ID command format is:
91hFFh(Veris type), Full-Data, Modbus, (CT value) Amp
The following is an example command with CT set for 100A:
91hFFhVeris H8036-0100-2, Full-Data, Modbus, 100 Amp
Example command explanation:
● 91h = version control
● FFh = standard for active
The 91h and FFh are 4 bytes in front of the string that are not displayed in the RTU.
Table 30: CT Amp Rating to Veris Models.
CT Amperage Rating Veris Model Number
CT ≤ 100A Veris Type = H8036-0100-2
CT Value = 100A
100A < CT ≤ 300A Veris Type = H8036-0300-2
CT Value = 300A
300A < CT ≤ 400A Veris Type = H8036-0400-2
CT Value = 400A
400A < CT ≤ 800A Veris Type = H8036-0300-3
CT Value = 800A
800A < CT ≤ 1600A Veris Type = H8036-1600-4
CT Value = 1600A
CT >1600A Veris Type = H8036-2400-4
CT Value = 1400A
