    What’s the definition of each bit of Setpoint Status Validity( Register2420-2421) in PM8240?

    Issue
    What is the definition of each bit of Setpoint Status Validity (Register 2420-2421) in a PM8240?

    Product Line
    PM8000 Series

    Environment
    PM8000 Register List

    Resolution
    Register 2420

    This register indicates which bits are currently activated.  Or it indicates which bit mapped inputs are NA.

    Bit 0 = Over I a - Validity (Status (Enabled or Disabled))
    Bit 1 = Over I b - Validity (Status (Enabled or Disabled))
    Bit 2 = Over I c - Validity (Status (Enabled or Disabled))
    Bit 3 = Over I 4 - Validity (Status (Enabled or Disabled))
    Bit 4 = Over V unbal - Validity (Status (Enabled or Disabled))
    Bit 5 = Over kW sd - Validity (Status (Enabled or Disabled))
    Bit 6 - Not Implemented
    Bit 7 - Not implemented
    Bit 8 - Not Implemented
    Bit 9 - Not implemented
    Bit 10 - Not Implemented
    Bit 11 - Not implemented
    Bit 12 - Not Implemented
    Bit 13 - Not implemented
    Bit 14 - Not Implemented
    Bit 15 - Not implemented

    Register 2421

    This register indicates the current state of the selected input (either True or False)

    Bit 0 = Over I a - Current State (True or False)
    Bit 1 = Over I b - Current State (True or False)
    Bit 2 = Over I c - Current State (True or False)
    Bit 3 = Over I 4 - Current State (True or False)
    Bit 4 = Over V unbal - Current State (True or False)
    Bit 5 = Over kW sd - Current State (True or False)
    Bit 6 - Not Implemented
    Bit 7 - Not implemented
    Bit 8 - Not Implemented
    Bit 9 - Not implemented
    Bit 10 - Not Implemented
    Bit 11 - Not implemented
    Bit 12 - Not Implemented
    Bit 13 - Not implemented
    Bit 14 - Not Implemented
    Bit 15 - Not implemented

    Please look at the following example for more details:

    ION_Capture


    Mod_Capture

    In my above example there are the 5 inputs
    Over I a
    Over I b
    Over I c
    Over I 4
    Over V unbal
    Over kW sd

    These inputs all come from setpoint modules.
    In the setpoint modules I went into the setup registers for Over I b, and changed it from enable to disable.

    If you compare the input values from the ION Capture to the Mod_Capture you will see confirmation of these parameters.

    2420 is showing 0 for Bit 1, and looking at the ION input links screen you can see that Over I b is NA, due to me disabling the setpoint module.  All other Bits are active so all other setpoint modules are working, and this is reflected by a 1 (enabled_ for Bits Over Ia , Over Ic, etc)

    2421 is showing the state of the inputs.  In my example, I have configured my device to have True originate at my setpoint module for Over I 4, which can be seen on the Capture screen shot as it has  a True as it's status.  This is reflected in the modbus register read for Bit 4 being set to 1 for True.
