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.
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.
➊ Denotes revision level of user manual. Example: Publication 20COMM-UM002C-EN-P is at
revision C.
Communication Ports The SMC 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 modules listed above to the internal DPI comm card connection.
Human Interface Module The SMC-FLEX controller can be programmed with the built-in
keypad and LCD display or with the optional Bulletin 20-HIM LCD
human interface modules. Parameters are organized in a three-level
menu structure and divided into programming groups.
