status.system.*
status.system.condition
status.system.enable
status.system.event
* = condition, enable or event
Attribute TSP-Link system data structure register set.
Reads condition, enable and event registers:
Usage
enablereg = status.system.condition
enablereg = status.system.enable
enablereg = status.system.event
Writes to enable register:
status.system.enable = enablereg
Set enablereg to one of the following values:
0
or
1 status.system.EXTENSION_BIT
or
1 status.system.EXT
status.system.NODEn
Remarks • In an expanded system (TSP-Link), this attribute is used to read or write to the system
node registers.
• Reading a system node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system node register are identified as
follows:
Bit B0 – EXT bitBit B4 – Node 4Bit B8 – Node 8Bit B12 – Node 12
Bit B1 – Node 1Bit B5 – Node 5Bit B9 – Node 9 Bit B13 – Node 13
Bit B2 – Node 2Bit B6 – Node 6Bit B10 – Node 10 Bit B14 – Node 14
Bit B3 – Node 3Bit B7 – Node 7Bit B11 – Node 11 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 3) are set.
• Assigning a value to the status.system.enable attribute sets the extension bit or a
node bit of the system node enable register.
