Chapter 8 Communication
If enabling control from the built-in SMC Flex programmer, the Logic Mask
must be set as follows:
Table 12 - Logic Mask Requirements
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.
Loss of Communication and
Network Faults 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.
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 ports 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
IMPORTANT Stop commands override all start commands and can be initiated from the
hardwired inputs or any port regardless of the logic mask.
