      How is current unbalance calculated on the DM6200?

      The Current Unbalance formula is not detailed in the DM6200 User Manual.

      Product Line

      Reading verification

      The current unbalance is calculated using the following equation:

      I unbalance = (Max phase current - Min phase current) / Avg 3 phase current * 100

      For example:

      Ia = 100 A
      Ib = 120 A
      Ic = 150 A

      Therefore, Max phase current = 150 A, Min phase current = 100 A, and Avg 3 phase current = (100 + 120 + 105) / 3 = 108.3 A.

      I unbalance = (150 - 100) / 108.3 * 100 = 46.2 % unbalance

      What is the part number for the 2 pin 32V 15amp plug to go with the 438/32?

      The part number for the 2 pin 32V 15amp plug to go with the 438/32 is - 492/32

      Starting Register number in Modbus Read functions

      Goals and Symptoms

      When performing Modbus read commands, it is important to apply the right starting register address in the read function. Otherwise, the wrong register will be accessed from the meter, giving unexpected data for the meter parameter being read.

      • Meter is functioning as expected. The front panel values for voltages and currents are within expected ranges for the system being monitored. However, modbus read functions from a master station (e.g. a PLC) give values that do not correspond to the front panel values.

      Facts and Changes

      Modbus, modbus rtu, function read, modbus map, holding register, staring register, function 03, modbus read packet

      Causes and Fixes

      One probable cause would be that, the modbus function read command is not pointing to the right registers. The modbus protocol requires an offset to be introduced in the starting register address when reading the slaves register.


      When reading the meter parameters, the Master must send the device a Read Holding Registers packet. This packet must specify a start register and the number of registers to read. When the function read is received, the slave responds with a packet containing the registers in the range defined in the read request.

      However, consider the 3710 Modbus map, which states that according to the MODBUS protocol, in response to a request for address 4xxxx, the master reads register xxxx-1 from the slave (3710). For example, a request for register 40011 returns register 10 from the slave.

      What does the above statement mean? Why is an offset required?

      Holding registers, by default, are defined the 4xxxx range, the first holding register staring at 40001. The starting register in the read packet is, on the other hand, numbered from zero. Hence, the start register zero automatically points to holding register 40001, starting register one points to holding register 40002, etc. The fact that the first holding register is 40001 and not 40000 explains the offset that needs to be introduced in the starting register number.

      Hence, considering the 3710 Modbus Map statement, if the Master needs to read register 40011, then the corresponding starting register that needs to be put in the read function would be 10 (0A hex) since register 40011 is the register 10 from the first holding register, 40001:
      40001 > Start register 0
      40002 > Start register 1
      40003 > Start register 2
      40004 > Start register 3
      40005 > Start register 4
      40006 > Start register 5
      40007 > Start register 6
      40008 > Start register 7
      40009 > Start register 8
      40010 > Start register 9
      40011 > Start register 10

      The Modbus Read Request Packet for a master reading 3 registers from a slave with unit ID 100 (64 Hex) and for starting register of 40011 should be:

      Slave ID
      Start Register (40011)
      # of Registers
      CRC Checksum

      To summarize, when looking at a modbus map, the starting register number to be used in the read function:

      Start Register = Modbus Register 40001.

      Scripting with APC by Schneider Electric Switched Rack Power Distribution Units (PDUs)


      Looking for assistance with scripting or automating outlet control on Switched Rack PDUs.

      Product Line
      • AP79XX Switched Rack PDUs
      • AP86XX, AP89XX Switched Rack PDUs

      • All serial numbers
      • All firmware versions
      • Scripting via Telnet, SSH, SNMP, or Local Console
      • Users using Network Port Sharing (sharing one IP address across up to (4) AP8XXX series Rack PDUs)
      • Users not using Network Port Sharing


      Many users like to automate outlet control actions using scripting. The following information is available for AP79XX, AP86XX, and AP89XX Rack PDU devices.


      Please refer to the appropriate section for your PDU device type.

      AP79XX Switched Rack PDU Series

      APC by Schneider Electric Switched Rack PDUs, beginning with part number AP79XX offer a command line interface for easy scripting to automate outlet control.
      In order to access this interface, you must interface with the PDU via terminal (local access with the serial cable), telnet or SSH. Upon receiving a username and password prompt via one of these access methods, enter the following credentials:

      User Name : apc
      Password : apc<space>-c

      (Passwords usually show as *** or blank as you're typing for security purposes)

      You will then receive the following information upon accessing the PDU command line interface:
      American Power Conversion
      Rack PDU AP7900 v3.7.3

      Please see the attached document for all available commands and assistance with scripting in conjunction with the Switched Rack PDU. If you have any questions or concerns, please contact APC by Schneider Electric technical support.

      Alternatively, AP79XX Rack PDUs offer outlet control via Simple Network Management Protocol v1 or v3 (SNMP). The PowerNet MIB is available from as a downloadable file which contains all of the particular OIDs to control the outlets.

      AP86XX and AP89XX Switched Rack PDU Series

      AP86XX and AP89XX Second Generation Switched Rack PDUs offer backwards compatibility with the aforementioned scripting interface but also offer command line access to the embedded Network Management Card 2. These methods can be used on PDUs whether or not they are part of a Network Port Sharing group. Please refer to the Rack PDU's user's guide for available Rack PDU device commands. These are typically added to between firmware versions. can be used to search by product for user's guides. For example, enter AP8941 which is the model of a PDU and all of the associated documents will be listed.

      Alternatively, AP86XX and AP89XX Rack PDUs offer outlet control via Simple Network Management Protocol v1 or v3 (SNMP). The PowerNet MIB is available from as a downloadable file which contains all of the particular OIDs to control the outlets. Any AP8XXX specific SNMP OID is located under / ., where under rPDU2.rPDU2Outlet.rPDU2OutletSwitched /. is where you'll find the outlet control OIDs.
      Please note: Scripting outlet actions is not available on APC Metered Rack PDUs because they do not offer individual outlet control.
