Device loops that are Special Device types do not show all possible commands.
The faceplate for a Special Device type only shows four of 16 possible outputs. A
possible CCF workaround is to not connect the device loop to the I/O and outputs
numeric 0 through 16. Instead, the value is decoded in a loop with a GET, some
logic, and DOT fcms to generate the actual output.

The device loop reduced faceplate, Figure 8, is also used to modify command,
mode, and state.
Continuous Loops
Indicator loops measure the values of process variables. The types of information
that are included on a Loop Detail Display or a faceplate for indicator loops are: tag,
descriptor, measured variable, engineering units, and alarm indications.
Figure 9 is an example of the types of information that are included on a faceplate
for a calculator type continuous loop. Calculator loops perform calculations on their
inputs. You can use the results of the calculations in other loops.
