ATTENTION: Risk of injury or equipment damage exists. The
examples in this publication are intended solely for purposes of
!
example. There are many variables and requirements with any
application. Rockwell Automation does not assume responsibility or
liability (to include intellectual property liability) for actual use of the
examples shown in this publication.
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.
