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 Block

Transfer is used to send Explicit Messages that 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 Block

Transfer to send Explicit Messages to write parameter data to

NVS. Datalinks do not write to NVS and should be used for

frequently changed parameters.
