Continuous Loops - ABB 800xA Operation

Continuous Loops

The device loop reduced faceplate,
mode, and state.
Figure 8. MOD CCF Device Loop Reduced Faceplate
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.
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.

inputs. You can use the results of the calculations in other loops.
