114 Set Parameter Object
Write Behavior USINT 1 Determines whether the Set_Attribute_Single
(write) service to a parameter object will cause the
parameter value to be saved to both nonvolatile
(NVMEM) and volatile (RAM) memory or just to
volatile memory. By default, most parameter values
are written to both volatile and nonvolatile memory.
However, if the Parameter Object Write Behavior is
set to 1 - No NVMEM Writes, then parameter values
are only written to volatile memory.
0 - Writes to NVMEM (default)
1 - No NVMEM Writes
Note: This parameter (114) does not affect how
parameter values are saved when an I/O or explicit
message writes a parameter value via an Assembly
Object.
Note: This parameter (114) is always written to both
volatile and nonvolatile memory. Setting this
parameter to 1 - No NVMEM Writes allows a user to
frequently change parameter values without
exceeding the nonvolatile memory's limited number
of write cycles. Typically, a user will not modify this
parameter.
Note: Some parameter values are not saved to
nonvolatile memory. Example: Parameter 22 - Reset
Faults, Parameter 27 - Host Enable, Parameter 29 -
Velocity Setpoint.
