IMPORTANT
If Explicit Messages are to be used frequently to
change the value of parameter objects, refer to
Parameter 114 - Parameter Object Write Behavior. By
default, an Explicit Message Set_Attribute_Single
service causes a nonvolatile memory (NVMEM)
write. However, the nonvolatile memory has a
limited number of write cycles. Change Parameter
114 - Parameter Object Write Behavior to 1 - No
NVMEM Writes to prevent writing the nonvolatile
memory. Parameter values will continue to be
written to volatile memory (RAM).
•Parameters 22–26, 63, 347–349, and 351 (which
have a No Action (0) selection) are not saved in
volatile or non-volatile memory.
•Parameters 27–30, 95, 101–102, and 350 are not
saved in non-volatile memory, but are saved in
volatile memory.
Note: Explicit Get commands have no effect on
NVMEM.
