Connecting the Human Interface Module to the Controller

Figure 7.1 shows the connection of the SMC-Flex controller to a
human interface module. Table 7.C provides a description of each
port.

Note: The SMC-Flex only supports the use of DPI communication

modules and DPI HIM LCD Modules. Scanport devices are
not supported by the SMC-Flex.

See Figure 3.14 on page 3-16 for the control wiring diagram that
enables start-stop control from a human interface module.
