Note: address 408225 and 408227 are both ground current. According to the set point ‘Ground Sensing’ setting in set
points group 1: protection group, the actual ground current would be displayed in related register and value in the other
register would be zero. For example, if the ‘Ground Sensing’ setting is 0, representing the ground current sensing type is
residual ground current. IG residual in address 408227 would be the actual value and IG source in address 408225 would
be zero.
10.3.5 Block of registers
A block of registers can be established in trip unit to remap the data object registers of an
Eaton product. The block of registers is stored in non-volatile memory.
Function code 16 is used to load the object assignments for the block of registers. The block
assignments are stored beginning at 401001/420481 (0x03E8/0x5000). Only the first data
object register address is assigned within the block of registers. For example, although data
object IA occupies register 0x1202 and 0x1203, only register 0x1202 is loaded into the block
of assignment registers. Verification of this block of assignment registers can be read from
trip unit with a function code 03 or 04 from these 401001/420481 (0x03E8/0x5000) registers.
Data pertaining to the objects configured in the block of assignment registers is mapped into
registers starting at 401201/420737 (0x 04B0/0x5100) and continuing in successive order for
each object assigned. The number of objects and their placement order in this data block of
registers is dependent on the configuration of the block of assignment registers. The total
number of data block of registers is limited to 100.
The data can be obtained from the data block of registers by a read function code 03 or
04. The address of the starting object must be aligned with a starting address of an object
within the data block of registers. The number of registers to obtain must align with an
ending address of an object within the data block of registers.
