A.3.5 Block of Registers
A block of registers can be established in trip unit to remap
the data object registers. 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 (0x04B0/0x5100) 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.
