DeviceNet Communications Module
The following figure shows how the I/O image table for a DeviceNet
scanner relates to the 1336 IMPACT drive when a DeviceNet
Communications Module is used.
Supported SCANport Messages
The 1336 IMPACT drive supports the following SCANport messages.
The formats and methods to use these messages vary depending on
the type of gateway used. Not all gateways support messaging or all
message types. Consult your gateway manual(s) or application notes
when determining the level of support for any gateway.

!
ATTENTION: Hazard of equipment damage exists. If
messages (block transfer messages, explicit messages,
unscheduled messages, etc.) are programmed to
frequently write parameter data to a drive, the EEPROM
(Non–Volatile Storage) will quickly exceed its life cycle
and cause the drive to malfunction. Do not create a
program that frequently writes messages to a drive.
Datalinks do not write to the EEPROM and should be
used for frequently changed parameters.
