Device Peripheral Interface (DPI) Protocol
The SMC-50 soft starter communicates in the same manner as the drive products
using the DPI protocol. This enables almost any DPI-supported Human
Interface Module (HIM), PC software (such as Connected Components
Workbench™ software), or network communications module (20-COMM-xx) to
be used with the SMC-50 control module. The SMC-50 module supports four
DPI ports for communication devices. Port #1 is located in the module bezel for
the front-mounted HIM. Port #2, located on the top of the module, supports a
second and third device via Port #3 when a DPI splitter is used. Port #4, located
directly below the module bezel, is dedicated to a 20-COMM-xx network
communications module when inserted into the space alloted for module option
Port #9. All four communication ports can be used simultaneously.
DeviceLogix
DeviceLogix is an embedded control technology in selected Allen-Bradley
products that can control outputs and manage status information on board a
device. The SMC-50 control module with DeviceLogix technology can help
improve system performance and productivity by controlling outputs and
managing status and information within the SMC-50 module. Processing
information within the controller can speed up reaction time, which reduces
dependency on network throughput and provides an option for decision making
if communication with the main control module is lost.
TIP For MV applications, refer to
Status Indication on page 37 for additional
details. I/O used for the start and stop command are from the 150-SM4 option
module.
