Section 3.4.3 Loop Definition and FCM Templets

3BUR 001 085R0001 REV A 3-29

These loops require completion of the following templets:

3.4.3 Loop Definition and FCM Templets

Basic information about the fields on the Loop Definition Templet and FCM Templets is

provided in the Configurable Control Functions (CCF) instruction book. The following

description provides supplemental information for fields requiring specific entries to define a

loop whose input is from a smart device. Figure 3-13 contains an example of a Loop Definition

Templet.

Continuous Loop Definition and FCM as required by the loop

FCMs of Continuous For CCF loop inputs and outputs, analog input, analog output,

digital input, digital output, and pulse duration output FCMs can

be used by continuous loops that support smart devices. Pulse

input and pulse train output FCMs must not be used. The templets

are described in the Configurable Control Functions (CCF)

instruction book. For the Analog Input FCM Templet, where there

are special considerations for smart device support, some

parameters of the templet are described in this section.
