Details
In an expanded system (TSP-Link), these attributes are used to read or write to the system summary registers.
They are set using a constant or a numeric value, but are returned as a numeric value. The binary equivalent of
the value indicates which register bits are set. In the binary equivalent, the least significant bit is bit B0, and the
most significant bit is bit B15. For example, if a value of
1.02
(which is 129) is read as the value of the
condition register, the binary equivalent is 0000 0000 1000 0001. This value indicates that bit B0 and bit B7 are
set.

the following table.
Bit Value
Description
B0
status.system2.EXTENSION_BIT
status.system2.EXT
Bit B0 decimal value: 1
B1
status.system2.NODE15
Bit B1 decimal value: 2

Bit B3 decimal value: 8
B4
status.system2.NODE18
Bit B4 decimal value: 16
B5
status.system2.NODE19
Bit B5 decimal value: 32
B6
status.system2.NODE20
Bit B6 decimal value: 64
B7
status.system2.NODE21
Bit B7 decimal value: 128
B8
status.system2.NODE22
Bit B8 decimal value: 256
B9
status.system2.NODE23
Bit B9 decimal value: 512
B10
status.system2.NODE24
Bit B10 decimal value: 1,024
B11
status.system2.NODE25
Bit B11 decimal value: 2,048
B12
status.system2.NODE26
Bit B12 decimal value: 4,096
B13
status.system2.NODE27
Bit B13 decimal value: 8,192
B14
status.system2.NODE28

Not used
Not applicable
As an example, to set bit B0 of the system summary 2 enable register, set
status.system2.enable =
status.system2.EXT
.
In addition to the above constants,
enableRegister
can be set to the numeric equivalent of the bit to set. To
set more than one bit of the register, set
enableRegister
to the sum of their decimal weights. For example, to
set bits B11 and B14, set
enableRegister
to 18,432 (which is the sum of 2,048 + 16,384).
