Preface
Thank you for purchasing the Comat BoxX series intelligent controller from our company.
Whilst you may have a good knowledge and understanding of these products you are re-quested to
take some time to read this manual before operation. This will allow you to utilise the more
advantageous benefits of the product.
The Comat BoxX series intelligent controller uses function blocks for programming and a liquid
crystal display is provided for manual programming.
In the past the control function of a PLC required large sections of program and instruction sets
whereas the Comat BoxX series uses function blocks. When several function blocks are linked
together in a specific way then relatively complicated control functions can be implemented so that the
programming can be simplified.
The Comat BoxX series intelligent controller can be used very extensively for automation of
mechanical equipment, flow control, building management systems and many other fields.
This manual will describe in detail the functional characteristics and operating method of the Comat
BoxX series controller.

Chapter I
Brief introduction to Comat BoxX
1.1 Structure of Comat BoxX
The Comat BoxX intelligent controller is a new type of programmable controller. As it is programmed
by means of function blocks. It is simpler and easier to learn the programming of Comat BoxX than
conventional PLC programming (ladder diagram and instruction).
In the design concept of the products of the Comat BoxX series, the PLC is combined with a writer
where the program can be written directly with the functions keys on the LCD front panel. The
product is very compact and lightweight despite the many functions including local and remote
communication networking and monitoring.
Also there are telephone control, voice prompting and automatic dial functions by adding the
AF-MUL voice block.
At present the Comat BoxX is widely used in various industries in the agricultural and the home
automation market and can be used almost anywhere.

1.3 Features of Comat BoxX
1. Removable programming panel with Liquid Crystal Display
There is an operating panel with LCD display on the front of the Comat BoxX (see note below).
The program can be edited with the operating keys on the LCD panel.
This panel can be removed for security purposes and be replaced with a cover (CAP).
Note:
The LCD panel can be plugged in or removed only after the power has been turned off.
2. Exquisite and compact design
Comat BoxX is an excellent choice to control your systems. Its performance and compact design,
offers you great opportunities of economical control solutions.
Type AF-10….: 90 x 71 x 58mm
Type AF-20….: 90 x 126 x 58mm
3. Large storage capacity
Control functions of Comat BoxX can be implemented with simple function blocks available in a
library.
The 20 pre-defined functions make programming easy and fast. The linking of function blocks
allows relatively complex control programs. A Comat BoxX has up to 127 function blocks for
program storage. A downloaded program into the EPROM can not be lost and does not require
battery backup.
4. Quick II programming software
QUICK II is a free-of-charge programming software
By using QUICK II, the program can be edited directly on the LCD panel or on a PC. The
program is loaded and written into the memory of Comat BoxX. QUICK II is a very friendly man-
machine programming interface. It cannot only edit the function diagrams, but it also can run and
analyse the written program. It provides an off-line testing function to the user to avoid
inconveniences for on-line testing. QUICK II will not only guide you to implement or edit the
control programs, but also performs real-time monitoring for field environment and operation
conditions of Comat BoxX.
5. Real-time clock function
Comat BoxX intelligent controllers have an instant real-time clock function, and can execute
timed operations according to various schedules. You can set as many as up to 127 different time
intervals which makes the Comat BoxX most suitable for systems which require time control.
6. Digital and Analogue inputs
In addition to receiving switching inputs (Digital), Comat BoxX can also process analogue inputs.
This allows to monitor and control temperature, humidity, pressure, flow, level, etc., The values
can be transmitted to a remote to PC for data supervision.
7. Remote programming, supervision and control of data through a MODEM.
To implement programming, write and modify programs from a distant location, it is only
necessary to connect Comat BoxX over a MODEM with a telephone line. It is also possible to
perform data acquisition and real-time supervision and control over the MODEM.

8. Security cipher code function
Comat BoxX is provided with a safety access code for the programs written by you. You can set
your own cipher code before you write programs. The programs can be modified only after the
correct access code is entered.
9. Telephone function
Comat BoxX is equipped with telephone and voice function blocks. It is possible to access Comat
BoxX directly through the normal telephone line.
Comat BoxX can dial out automatically, so as to implement notice or alarm functions. Moreover,
Comat BoxX can also receive the signals transmitted from a remote location through the telephone
line (or a cell phone) in order to control connected devices or machines.
Note:
It is necessary to configure AF-MUL multi-functional voice block for the
implementation of telephone and voice function.
10. Voice function
If connected to the AF-MUL Voice unit, Comat BoxX is able to broadcast alarms or messages
either over auxiliary speakers or a telephone line. This unique feature offers many additional
possibilities for the automation and control industry.

Note:
1. AF-10MR-D, AF-10MT-GD, AF-20MR-D and AF-20MT-GD can all receive analogue inputs
through all input interfaces (I1-I6 or I1-I12). They are automatically set to analogue or digital
input. An analogue signal is recognised when the input terminal is connected to the AN function
block. It is important to set analogue inputs first when using SCADA software.
2. The analogue input requires 0V ~ +10V voltage signals and is divided equally in 0.1V increment
steps. When programming, all the block parameters related to analogue are based on the minimum
precision of class 1.
3. All inputs over 10.0V are recognised as digital inputs.
4. Digital inputs: Change of status from „0“ to „1“ : Triggering time min. 50ms
Change of status from „1“ to „0“ : Triggering time min. 50ms

2.2.3 Connecting of Comat BoxX output
The AF-10MR-A, AF-10MR-D, AF-20MR-A, AF-20MR-D, all have relay outputs.
The AF-10-MT-GD (PNP), AF-20-MT-GD (PNP) are transistor output types. It is necessary to have a
separate power supply for the load. The power supplies must have the same potential.
1. Requirement for the relay output
Various loads such as lamps, fluorescent tubes, motors, contactors, etc., can be connected to the
outputs of Comat BoxX. The max. ON output current that can be supplied by the Comat BoxX
controller is 8A for resistive load.
Compare datasheet in Chapter III.
The connection is shown as follows:
Fig. 2.9 Relay output
2. Requirements for the electronic transistor output
The maximum switch current should not exceed 2A; when the switch is ON (Q=1).
Compare datasheet in Chapter III.
The connection is as the shown below:
Fig. 2.10 Transistor output
Note:
Output Q must be on the same potential as input I.
