status.system4.*
status.system4.condition
status.system4.enable
status.system4.event
* = condition, enable or event
Attribute TSP-Link system4 data structure register set.
Reads condition, enable and event registers:
Usage
enablereg = status.system4.condition
enablereg = status.system4.enable
enablereg = status.system4.event
Writes to enable register:
status.system4.enable = enablereg
Set enablereg to one of the following values:
0
or
1 status.system4.EXTENSION_BIT
or
1 status.system4.EXT
status.system4.NODEn
Remarks • In an expanded system (TSP-Link), this attribute is used to read or write to the system4
node registers.
• Reading a system4 node register returns a numeric value whose binary equivalent
indicates which register bits are set. The bits of the system4 node register are identified as
follows:
Bit B0 – EXT bitBit B4 – Node 46Bit B8 – Node 50Bit B12 – Node 54
Bit B1 – Node 43Bit B5 – Node 47Bit B9 – Node 51Bit B13 – Node 55
Bit B2 – Node 44Bit B6 – Node 48Bit B10 – Node 52 Bit B14 – Node 56
Bit B3 – Node 45Bit B7 – Node 49Bit B11 – Node 53 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 45) are set.
• Assigning a value to the status.system4.enable attribute sets the extension bit or a
node bit of the system4 node enable register.
