Rockwell Automation 150 USE MN/SMC DIALOG + CONTROLLER - Manual (Page 113)

8-4 Serial Communications
Display Unit
Equivalents Some parameter setting options use a text description when viewed
from the built-in LCD display or a human interface module. An
example is the parameter, Starting Mode, which has the available
settings of Soft Start and Current Limit. Table B.2, found in
Appendix B provides the required display unit decimal equivalent for
use when sending a command from a logic controller to the SMC
Dialog Plus controller.
Datalinks The SMC Dialog Plus controller does not offer Datalinks.
Interfacing Refer to the appropriate communication module manual for detailed
information regarding communication module installation, DIP
switch settings, block transfer instructions, and communication
module troubleshooting.
Processing Time The typical time for the SMC Dialog Plus controller to process a
single parameter data request (i.e., block transfer) via the SCANport
is approximately 100 msec. Keep this value in mind when
determining the message length of multiple parameter value read or
write operations.
