1560E-UM050B-EN-P - June 2013
If enabling control from the built-in SMC-Flex programmer, the Logic
Mask must be set as follows:
Table 8.D – Logic Mask Requirements
Mask Code Description
0 No external DPI devices are enabled
4 Only one HIM on port 2 is enabled
12 Two HIMs are enabled on ports 2 and 3
32 Only the DPI communication card on port 5 is enabled
36
One HIM on port 2 and the DPI communication card
on port 5 are enabled
44
Two HIMs on ports 2 and 3 and the DPI communication card
on port 5 are enabled
Control Enable
The Logic Mask parameter (Parameter 87) allows the user to configure
whether a communication device (HIM or network connection) can
perform control commands such as starting. Each communication port can
be enabled or disabled as required. When a given device is enabled through
the logic mask that device is allowed to execute control commands. In
addition, disconnecting any device with the logic mask enabled will result
in a communication fault unless the communication fault is disabled. When
a given device is disabled through the logic mask that device cannot
execute control commands, but can still be used for monitoring. A device
that is disabled through the logic mask can be disconnected without
causing a fault.
Stop commands override all start commands and can be
initiated from the hardwired inputs or any port
regardless of the logic mask.
The loss of communication fault will follow the functionality as defined in
the DPI specification. There will be separate faults for each device. Since
three DPI ports are supported there will be three faults that can be generated.
DPI provides a separate network fault for each port. This fault can be
generated directly by the peripheral and is separate from the Communications
Loss fault (which is actually generated by the SMC-Flex itself).
SMC-Flex Specific Information
The SMC is can be used with all LCD applicable DPI interface. Regardless
of the type of interface being used, the information below can be used to
configure the rest of the system.
