status.system3.*
status.system3.condition
status.system3.enable
status.system3.event
* = condition, enable or event
Attribute TSP-Link system3 data structure register set.
Reads condition, enable and event registers:
Usage
enablereg = status.system3.condition
enablereg = status.system3.enable
enablereg = status.system3.event
Writes to enable register:
status.system3.enable = enablereg
Set enablereg to one of the following values:
0
or
1 status.system3.EXTENSION_BIT
or
1 status.system3.EXT
status.system3.NODEn
Remarks • In an expanded system (TSP-Link), this attribute is used to read or write to the system3
node registers.
• Reading a system3 node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system3 node register are identified as
follows:
Bit B0 – EXT bitBit B4 – Node 32Bit B8 – Node 36Bit B12 – Node 40
Bit B1 – Node 29Bit B5 – Node 33Bit B9 – Node 37Bit B13 – Node 41
Bit B2 – Node 30Bit B6 – Node 34Bit B10 – Node 38 Bit B14 – Node 42
Bit B3 – Node 31Bit B7 – Node 35Bit B11 – Node 39 Bit B15 – Not used
• For example, assume value 9 is returned for the enable register. The binary equivalent is
0000000000001001. This value indicates that bit 0 (EXT) and bit 3 (Node 31) are set.
• Assigning a value to the status.system3.enable attribute sets the extension bit or a
node bit of the system3 node enable register.

Example Sets the extension bit of the system3 enable register:
status.system3.enable = status.system3.EXT
