As an example, to set bit B0 of the standard event status enable register, set status.standard.enable =
status.standard.OPC.
In addition to the above constants, standardRegister can be set to the numeric equivalent of the bit to set. To
set more than one bit of the register, set standardRegister to the sum of their decimal weights. For example,
to set bits B0 and B4, set standardRegister to 17 (which is the sum of 1 + 16).

Example 1
standardRegister = status.standard.OPC
+ status.standard.EXE
status.standard.enable = standardRegister
Uses constants to set the OPC and EXE
bits of the standard event status enable
register.
Example 2
-- decimal 17 = binary 0001 0001
standardRegister = 17
status.standard.enable = standardRegister
Uses a decimal value to set the OPC and
EXE bits of the standard event status
enable register.

system summary register of the status model for nodes 1 through 14.

Usage
enableRegister = status.system.condition
enableRegister = status.system.enable
enableRegister = status.system.event
enableRegister = status.system.ntr
enableRegister = status.system.ptr
status.system.enable = enableRegister
status.system.ntr = enableRegister
status.system.ptr = enableRegister
enableRegister
The status of the system summary register; a zero (0) indicates no bits set; other
values indicate various bit settings
