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".

Watlow F4T •8 •Chapter 1 Overview
Outputs
Outputs respond to information provided by a function such as, heat power from the output
of the control loop, driving a digital output based on a profile event, turn a light on or off,
unlocking a furnace door or turning on a buzzer.
More than one output can be assigned to respond to any given function, i.e., more than one
output device could be connected to the heat output of the control block. Another example
(not shown), could use the (internal) output of the alarm function and connect it to any avail-
able real-world output to trigger a flashing light and another real-world output that might be
connected to a siren.
What is a Profile
A profile is a set of instructions consisting of a sequence of steps. When a profile runs, the
controller automatically executes its steps in sequence. The step type determines what ac-
tion the controller performs. Steps can change temperatures and other process values gradu-
ally over time, maintain the temperatures and process values for specific periods, or repeat a
sequence of steps numerous times. At each step the profile can activate or deactivate outputs
that control other equipment. Also a step can have the controller wait for specific conditions
before proceeding such as, waiting for a switch closure and/or a specific process value to be
detected by a sensor.
Data Logging
Controllers equipped with this feature will have the letter [J, K, L or M] in the fifth character
of its part number (see: F4T Ordering Information). Logging can be enabled at any time and is
intended to capture real-time data for a user selectable list of data points. With firmware re-
vision 3.0 and above, several new features are available.
1. User can determine if logged files will be moved automatically and or manually.
2. Destination of the saved file can be directed to internal memory, USB thumb drive, TFTP
server or a Samba shared drive.
3. Based on user choice, files can now be encrypted (filename.enc) for security purposes and
or saved as comma separated values (filename.csv). Creating both file types allows viewing
of the csv file while maintaining the integrity of the encrypted file.
To learn more about configuring these options see the section in this user's guide entitled Set-
ting Up Data Log Files Using Composer.

Composer Welcome Screen Orientation
The graphic below illustrates and defines some points of interest as seen on the Composer
Dashboard screen and describes the functionality, numbered correspondingly.
① Dashboard (Systems)
• Displays options for on-
line connections between PC
and a controller or opening a
previously saved system image.
② Data Logs Menu
• Decrypt Log File: allows for de-
cryption of an encrypted data log
file.
• View: displays the con-
tents of a data logged file
(enc or csv). Depending on files size this may take several minutes to open.
To decrypt an encrypted file follow the steps below:
1. If data logging has not yet been stopped do so now by pushing: Main Menu -> Data Log-
ging -> Stop buttons.
Note:
When data logging is stopped, allow at a minimum, six minutes for closure of all
files and movement of those files to the selected destination before attempting de-
cryption.
2. Open up Composer software and click on Data Logs and then Decrypt Log Files.
3. Locate the encrypted files and open them one-by-one (click on one *.enc file and click
Open), or by selecting more than one and click the Open button.
Note:
If logged file is sent to USB, the *.csv and the *.enc file are written directly to USB
constantly. If the File Size Limit is set to 10MB or larger, the csv will continue to be
written continuously while the encrypted portion (*.enc) is chunked into 7.5MB files,
buffered internally and then written out as 7.5MB chunks. If the maximum file size
is set to 10MB, there will be two *.enc files for each csv (7.5MB and 2.5MB). If File
Size Limit is set to 15MB, there would be two 7.5MB *.enc files for each *.csv file.

Watlow F4T Controller •11 •Chapter 2 Configuration Using Composer
Note:
As noted above, if a csv file is greater than 10MB there will be more than one en-
crypted file for the associated csv file. When decrypting these files, it is recom-
mended that all encrypted files be selected in the decryption process. Each of the
encrypted files will be concatenated into one csv file.
4. After selecting the desired encrypted files and then clicking Open, the window below
will appear. Notice the filename of the original csv and the one suggested in the dialog
box highlighted yellow below. The one within parentheses (1) is inserted to avoid over-
