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, Inc. 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 Nonvolatile 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.
