Communications

The SMC-50 control module provides advanced communications capabilities
that allow you to start and stop it from multiple sources and provide diagnostic
information through the use of communication interfaces. The SMC-50 control
module uses DPI as an internal method of communication bus; therefore, all
standard DPI communication interfaces that are used by other devices (for
example, PowerFlex® Drives) can be used in the SMC-50 control module.
SCANport™ devices are not supported by the SMC-50 control module.
Standard DPI communications cards are available® for various protocols,
including DeviceNet, ControlNet, ModBus, and PROFIBUS DP. Other
modules may be available in the future. For specific programming examples,
configuration, or programming information, see the user manual for the
communication module being used.

The SMC-50 control module supports four DPI ports for communication. Port
1 is for the front-mounted (bezel) Human Interface Module (HIM). Ports 2 and
3 are supported through the serial connection on the top of the device and are
typically used to interface with a door mounted HIM or a PC. Port 2 is the
default connection with port 3 available by installing a splitter on port 2. DPI
Port 4 is supported by connecting one of the communication cards listed in
Table 45 to the internal DPI communication card connection (SMC-50 control
module hardware controller port 9).
