        How to change the power sign on 5.2E, 6.2E, 5.3E,6.3E trip units for Powerpact H, J and L frame breaker?

        Issue:
        How to change the power sign on 5.2E, 6.2E, 5.3E,6.3E trip units for Powerpact H, J and L frame breaker?

        Product Line:
        Powerpact H, J and L

        Environment:
        5.2E, 6.2E, 5.3E,6.3E Micrologic trip units

        Cause:
        Power values reading negative.



        Resolution:
        The power sign can be changed through Modbus register, or with RSU software and UTA test kit STRV00910.

        RSU:
        Modify the Power sign using the RSU software and UTA Tester STRV00910, see link for free RSU download.

        By default, the Micrologic E trip unit signs as positive the powers running through the circuit breaker supplied from the top with loads connected from the underside. Circuit breakers powered from the underside must have the powers signed as negative. 

        In the Metering setup/Power sign window, select the power sign:
        • + The power running through the circuit breaker from top to bottom is
        counted positively.
        • - The power running through the circuit breaker from bottom to top is
        counted negatively.
        The default value of the powersign is +.


        MODBUS:
        Power Flow
        Sign 3316 3315 RW — — UINT 0–1 E
        Power flow sign
        0 = the active power flows from upstream (top) to downstream (bottom) (default).
        1 = the active power flows from downstream (bottom) to upstream (top).
        The power flow sign command (command code = 47240) configures the content of the power flow sign register.

        8006 8005 — — UINT 0–1 E
        Power flow sign
        0 = the active power flows from upstream (top) to downstream (bottom)
        (default)
        1 = the active power flows from downstream (bottom) to upstream (top).
         

        How to set the RTU internal clock to the correct time via the SCADAPack?

        Issue:
        I am trying to set the RTU internal clock to the correct time via the SCADAPack E configurator à Transfer à Set RTU Time;
        However, the remote device time remains the same.
        Is there any other way to setup the RTU clock?

        Answer:
        Cause:

        RTU is set to take the time from network with NTP from Time Server

        Resolution:
        Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems and different controllers.

        RTU can update its time by two methods:
        1- Network Time Protocol (NTP) 
        2- Local Connected computer with SCADAPack E Configurator.

        If NTP option is checked, the user will not be able to set the time from SCADAPack E Configurator. 
        Please follow the following steps to resolve the problem:
        i) Open SCADAPack E configurator
        ii) Connect to Controller
        iii) Go to TCP/IP section and click on plus sign
        iv) Select TCP/IP
        v) Uncheck "NTP Network Time" from "Enable TCP/IP Services" sub-section

        Download the configuration to RTU.
        Now you can set the time from SCADAPack E Configurator by clicking on Transfer from the main menu and select "Set RTU Time"

         

        How are floating point values converted in Schneider Electric energy meters?

        Issue
        Some Powerlogic meters represent 32-bit Modbus registers as an IEEE 754 floating point data type 

        Product Line
        PowerLogic and ION Meters that support IEEE 754 floating point data types in Modbus registers

        Environment
        Modbus Floating Point Data Type

        Cause
        Internally, most Schneider PowerLogic meters use floating point representations (conforming to IEEE floating point standards) to represent large numbers (i.e. ones that don't fit easily into integer formats). The most common format is a 4 byte floating point (IEEE 754) representation. Some meters allow reading of values directly using Modbus protocol that are in this format (see specific meter’s Modbus Register Map for more details).

        Resolution
        The architecture of this number format is the following:

        S E F
        0 1_______8 9_______________________31

        S: sign
        E: exponent
        F: faction (also referred to as the mantissa or significand)

        calculation would be = (-1)^S * 2^(E [dec format]-127) * (1.F)[Base 10]

        Take frequency reading of PM700 as an example. If the frequency reading in floating point registers are:
        1020: 0100001001000111
        1021: 0000000000000000

        Combine 2 registers in binary format to become:
        01000010010001110000000000000000

        According to the IEEE Floating Point Standard, split the combined value according to the structure:
         
        S E F
        0 10000100 10001110000000000000000


        When S=0, it is a positive number (i.e. S=1 means the value is negative).
        The value in E is 10000100, which is 132 in decimal.
        The remaining portion is placed in F, which is 0.10001110000000000000000 (Base 2).
        1.F is 1.10001110000000000000000 in base 2, which equals to 1.55468750000000000000000 in Base 10
        1.554687500000000000000001.55468750000000000000000
        Placing this in the formula results in (-1)^(0) * 2^(132-127) * (1.55468750000000000000000) = 49.75
