Document Overview and Purpose
This document looks deeper at the system configuration using Composer™software and the
F4T function blocks and their associated connections. Common product usage is described and
illustrated through application examples.

Watlow F4T •6 •Chapter 1 Overview
A Conceptual View of the F4T System
The flexibility of the F4T controller hardware and software (Composer™) allows for a large
range of configurations. Composer software is a graphically based tool used to program the
F4T controller in its entirety. To learn more about installing and using Composer software see
Chapter 2 of this document in the section titled "Installing Composer Software".
Acquiring a better understanding of the controller’s overall functionality and capabilities while
at the same time planning out how the controller can be used will deliver maximum effec-
tiveness in your application.
It is useful to think of the controller in three parts: inputs, functions and outputs. For the
control itself, information flows from an input to a function to an output when the controller
is properly configured. The F4T system can carry out several functions at the same time; such
as, monitoring and acting upon various inputs (temperature sensing devices, pressure trans-
ducers and digital inputs), PID control, monitoring for several different alarm situations and
then driving output devices such as heaters, audible alarms, and lights. Each process needs
to be thought out carefully and the controller’s inputs, functions and outputs set up properly.
As an example, the graphic below illustrates the Function Block Diagram as seen when using
Composer software. The application requirements in this example are simple and defined be-
low:
• Need two thermocouple inputs.
• Monitor both thermocouple inputs for high process alarms.
• Drive an output (alarm) device if either input is higher than expected.
• Use one thermocouple input to drive the PID loop (Heat output) with a switched DC
output.
In the graphic below the following is true:
• Universal Input 1 is connected to the Process Value (PV) input of the control loop.
• When the control loop sees that the
PV is less than the user defined set
point it will drive the output to the
load through its heat (HT) output.
• Two unique high process alarms are
configured to monitor Universal Inputs
1 and 2.
• The logic function block (FB) is con-
figured as an OR where its output
will come on if either input comes on
driving the real-world digital output
(alarm) it's connected to.

Watlow F4T •7 •Chapter 1 Overview
Note:
In this configuration, the heat output of the control function would be uninterrupted if an
alarm were to occur.
You will find more detailed information regarding the function blocks and how they work fur-
ther on in this document.
Inputs
The inputs provide the information that any given programmed function can act upon. In a
simple form, this information may come from an operator pushing a button, or as part of
a more complex function it may represent a remote set point being received from another
zone.
Each universal input can be configured for thermistors, thermocouples, or RTDs to read the
process variable. They can also read mV/volts, current or resistance, enabling usage of various
devices to read humidity, air pressure, operator inputs and other values. The settings associ-
ated to each analog input must be configured to match the device connected to that input.
Each digital input reads whether a device is on or off (voltage or resistance) and each system
can be equipped with multiple digital I/O modules. Each I/O point must be configured to func-
tion as either an input or output.
Functions
Functions use input signals to calculate a value and or performs an action. A function may be
as simple as reading a digital input as on or off, or reading an analog value (temperature) to
set an alarm state to on or off. As an example, a user could use sensor backup to avoid an un-
wanted shutdown if a failure with the primary sensing device should occur.
Keep in mind that a FB can be a purely internal function (i.e., control loop, alarm, logic,
etc...), while they can also serve as a connection point between real-world devices (i.e., ther-
mocouple, heater etc...) and internal functions like a Universal Input connected to the Control
Loop PV input. To have an effect outside of the controller, an output FB must be configured
to respond to some other function. Functions and all associated dependencies would be con-
figured using Composer software. To learn more about setting up function blocks see Chapter
2 of this document in the section titled "Configuring the Application with the Function Block
Diagram View".
