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® • 7 • 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 effectiveness
in your application.

Outputs
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 transducers
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 below:
• 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:
Watlow F4T® • 8 • Chapter 1 Overview
• 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
configured 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.
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 further
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
associated to each analog input must be
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
function as either an input or output.
configured to match the device connected to that
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
unwanted shutdown if a failure with the primary sensing device should occur.
Watlow F4T® • 9 • Chapter 1 Overview
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. thermocouple, 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 configured using Composer software. To learn more about setting up function blocks
see Chapter 2 of this ocument in the section titled "Configuring the Application with the Func-
tion Block Diagram View".
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 available
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 action
the controller performs. Steps can change temperatures and other process values gradually
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
revision 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
Setting Up Data Log Files Using Composer.

Configuring Pluggable Flex Modules
This controller can have up to six Flex Modules (FM) installed in the chassis. The presence of
each FM must be confirmed and accepted using Composer
configured as installed hardware or the user can type in a valid FM part number for late
installation. For more detail regarding the module installation process, see the Installation and
Troubleshooting User's Guide for the controller in use.
Note:
Typing in a valid part number without the presence of the module is intended for the sole
purpose of building the FBD (connecting function blocks on the canvas). Errors may be
generated and all outputs will be off until the module is inserted.

Entering Flex Module Information Prior to Installation
Function blocks associated with hardware will not be available until the hardware is expected
to be present. Entering a part number for any slot (even though the module is not currently
installed) allows the programmer access to the associated function blocks. As an example, if
an FMMA-UEKA-AAAA is installed in slot one,
the function blocks that would be available are
shown in the red box. After entering a part
number such as FMLA-YEBA-AAAA in slot 2,
additional hardware dependent function blocks
will appear as shown in the blue box.
Note:
When configuring modules as described
above (not installed), the controller will not be
able to control any outputs. All outputs will be
off.
To configure the controller to expect a module that is not yet installed:
1. Select the desired slot and enter a valid part number in the Expected Part Number field.
2. On the keyboard, push the Enter key.
3. Click Finish when complete to restart the controller. After the restart process is complete

Getting Started with the Function Block Diagram (FBD)
The basic steps for creating the function block diagram for any application are:
1. Add the function blocks from the library to the canvas that are needed to interpret the
signals from the physical inputs and set the physical outputs. Typically, these will include
Loop, Alarm and Profile Engine function blocks.
2. Connect the transmitters on the FBs that source data to the receivers on the FBs that need
the data.
3. Set each function block's parameters as needed for the application to perform as expected.
Watlow F4T® Controller • 24 • Chapter 2 Configuration Using Composer
Detailed descriptions of each function block including all the function block's parameters can
be accessed in the online help for the function block and in the User's Guide, chapter entitled
Function Block Reference.
The FBs that represent the physical inputs and outputs from the controller and are associated
with the flex modules that are expected in the configuration are always on the canvas. These
FBs can only be removed by changing which modules are expected using the Pluggable
Modules view.
Other FBs can be added to the canvas from the library. Some of these FBs such as Loop,
Cascade, Alarm and Profile Engine perform sophisticated functions. See the Application
Examples chapter in this User's Guide for more on these functions. Other function blocks such
as Math and Logic perform fundamental functions that can be combined to add custom
behaviors to the controller for specific applications.
The signals that carry data between function blocks normally appear as black lines in the
diagram, but when the block that transmits the signal cannot determine what the correct value
should be, the signal changes to yellow indicating the error. Each FB's response to errors
received is explained in the description of the function block.
Warning:
Once an output FB receiver is connected to another block, the output on the flex module
turns on according to the received signal. Do not connect outputs until it is safe to do so.
Notable facts about the FBD:
• How a FB responds to its inputs and drives its output is dependent on its parameter
settings. Set the parameters for each function block as needed for the application.
• Signals cannot be moved after they are created; to change where a signal gets data or
where it delivers it, delete the signal and create the desired connection.
• There are several ways to do many things. Try right-clicking to see options or short cuts.
• FBs from the library that have no signals connected are returned to the library when
®
Composer
is closed.
• The location of dockable windows is not saved; windows return to their default locations
when the system is closed.
• The selection of signal values displayed in the diagram is not saved; all signal value
displays are turned off when the system is closed.
Hints:
• Click-and-drag any blank spot on the canvas to change the view.
• Use the scroll bars.
• Use the Navigator to reposition the view of the canvas and to zoom in or out.
• Use the mouse wheel to scroll the view. Hold the shift key to use the mouse wheel to
pan. Hold the Control key to use the mouse wheel to zoom.
Selecting and Placing Function Blocks on the Canvas
To place a FB on the Canvas:
1. Find the desired FB within the library (using scroll bars if present).
2. Click-and-drag the FB to the canvas.
Watlow F4T® Controller • 25 • Chapter 2 Configuration Using Composer
Moving Function Blocks
To move a FB on the Canvas:
• Click-and-drag the FB to the desired location on the canvas.
Hints:
• Click the main body of the FB not one of its transmitters or receivers. Clicking a transmitter
or receiver begins to draw a signal rather than move the FB.
• The canvas will scroll if the mouse pointer is close to the edge but not outside the diagram
window.
• To make a long move, click the block to select it, then zoom out to make it easier to move
the block to the desired location.
Connecting Function Blocks Together
To connect a transmitter to a receiver:
• Click and drag a signal from a FB's transmitter to a receiver on another FB.
Hint:
• This can also be accomplished in reverse, i.e., click and drag from a receiver to a
transmitter.
Viewing Signal Values and Errors
To momentarily display a signal's value:
• Mouse over (point the mouse cursor at) the signal.
To display a signal's value continuously:
1. Right-click the signal.
2. Click Show/Hide Data
To cancel (turn off) the signal display:
1. Right-click the signal.
2. Click Show/Hide Data
Note:
The values displayed are not in real-time.
Troubleshooting Signal Errors
While building the FB diagram, or during operation, there may be occasions when the signal
from the transmitter of a FB is displayed yellow. This may reflect that the FB has encountered
an error or some other anomaly has occurred. From the user perspective, an evaluation of the
cause should be done to ensure that unexpected operation does not occur. Suggested steps to
evaluate the cause of a yellow link are listed below:
Watlow F4T® Controller • 26 • Chapter 2 Configuration Using Composer
To evaluate the cause of a yellow signal:
1. Trace the yellow signal back to the source
(first occurrence of a yellow link) FB.
2. Place the mouse over the signal which will
display the error.
3. In this particular example, the error is identified as an Open sensor.
4. Click on the selected FB and view the Help window.
5. Search ("Ctrl-F") the help file for the word "Open".
6. Once found, evaluate, make note or correct the cause of the problem.
If further assistance is needed review the associated product User's Guides or contact the
Watlow Technical Support team (1-800-492-8569 or 1-507-494-5656).
Adjusting Function Block Behavior with Parameter Settings
To change a FB parameter:
1. Double-click on the FB.
2. In the Parameters window locate and change the parameter.
Note:
If names are applied here, those names will appear on the FBD
and if selected, the output view of the Personalization screen.
Finding Help for Function Blocks
To locate the help topic for a FB on the Canvas:
• Click the FB and view the help window.
Hints:
• Many function blocks can be configured to perform one of several functions. For these
FBs, the help topic has a section for each function. Locate and click the link for the desired
function.

Setting Up Data Log Files Using Composer
Data Logging can be enabled at any time and will log a user selectable list of data points.
While data logging is enabled, the data log file is stored within either the USB device memory
or internal memory. Once the file reaches a specified size (if being transferred automatically), it
will be sent directly to one of three other destinations (USB, TFTP server or a Samba server).
The file transfer can also be initiated manually at any time. The file transfer process from
internal memory, whether completed automatically or manually, will move all log files from
internal memory to the selected destination. To learn more about data logging see
"Data Logging" in the Overview Section of this User Guide.
Note:
Data logging can also be enabled/configured through Modbus. There are specific Modbus
registers for each of the parameters defined below.
Watlow F4T® Controller • 29 • Chapter 2 Configuration Using Composer
®
Topics discussed in this section follow:
Setup Data Logging: discusses required fields that must be set prior to starting data logging.
Configuring a Samba Shared Folder: identifies and gives illustrations in defining the necessary
user account and the shared folder.
Configuring a TFTP Server: details required setup fields while illustrating steps to successfully
move files from the F4T® to the TFTP destination.
Note:
Data logging is terminated when power is lost while the data log file itself will be maintained
where it was captured.
Setup Data Logging
To setup data logging, follow the steps below:
1. Click on the Device Menu tab.
2. From the drop down menu click on Data Logging.
3. Select and add all of the desired Data Points for the data log file.
Note:
Selected data points will be used whenever data logging is enabled.
4. Click on the Setup button.
- Logging Status: indicates whether or not recording is active or not.
- File Name: any alphanumeric characters, 63 maximum.
Note:
When transferring files via TFTP, do not create a file on the server called "testfile".
Communications between the F4T® and the TFTP server is tested prior to starting a
transfer using this filename while then verifying the response from the server.
- Log To: USB or Internal Memory.
Note:
When transferring files via TFTP or Samba, internal memory must be selected here.
Note:
There are many USB memory devices available. Watlow does not recommend using
micro SD or SD card to USB adapters in the USB slots. Be aware that we have not
tested all of the variations of USB memory devices but we have tested and validated
those that are listed below:
• Lexar, Kingston, Toshiba and Verbatim
Note:
Supported USB file systems: FAT16 and FAT32.
Note:
Due to wear-leveling operations of flash memory devices (internal - F4T® and external
- USB), there may be some gaps within the data logged file.
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.
