Communications
Overview
The SMC-Flex provides advanced communications capabilities that
allow it to be started and stopped from multiple sources as well as
provide diagnostic information through the use of communication
interfaces. The SMC-Flex uses the DPI method of communication,
therefore all standard DPI communication interfaces used by other
devices (i.e., PowerFlex
™
Drives) can be used in the SMC-Flex.
ScanPort devices are not supported by the SMC-Flex.
Standard DPI communications cards are available for various
protocols including DeviceNet, ControlNet, Remote I/O, ModBus
™
,
and Profibus
®
DP. Other modules may be available in the future. For
specific programming examples, configuration, or programming
information, refer to the user manual for the communication interface
being used. A list of available interfaces is located below.

revision C.
Communication Ports
The SMC-Flex supports three DPI ports for communication. Ports 2
and 3 are supported through the serial connection on the side of the
device and are typically used to interface with a Human Interface
Module (HIM). Port 2 is the default connection with port 3 available
by installing a splitter on port 2. Port 5 is supported by connecting one
of the communication cards listed above to the internal DPI comm
card connection.
