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.
