Function Legal Values
Client Side Write and Readback to be completed, and only
updates the data value if a data comparison between the Client
Side Write and Read values passes. If the transaction fails for
any reason or if the data comparison fails, the Server responds
with a negative acknowledgement.
Enable_Write_Retries*
The default write behavior is for a write operation (WRB or
WRBX) to be attempted once only. If a timeout occurs the
write operation is aborted. If set to yes, this parameter enables
failed write requests to be retried. The number and timing of
the write retries is then governed by the Retries and
Retry_Interval parameters.
Warning: ensure that repeated writes are safe for your
application since a Write may be retried because of a
transmission error in the Write acknowledgement, in which
case the remote device will see two similar write requests.
Yes, No
Node_Offline_Action*
If this parameter is defined, when a Client Node goes offline, all
Data Array values of Map Descriptors defined on this Node will
be set to zero.
