The examples in this publication are intended solely for

ATTENTION: Risk of equipment damage exists. If Explicit
Messages are programmed to write parameter data to
Non-Volatile Storage (NVS) frequently, the NVS will quickly
exceed its life cycle and cause the drive to malfunction. Do
not create a program that frequently uses Explicit Messages
to write parameter data to NVS. Datalinks do not write to
NVS and should be used for frequently changed parameters.
TIP: To message to another device in a different drive port, refer to the
Instance table in Appendix C:
•
DPI Parameter Object section on
for Device parameters.
•
Host DPI Parameter Object section on
for Host
parameters.
In the Message Configuration screen, set the Instance field to an
appropriate value within the range listed for the port in which the device
resides.
