-Applications where high reliabilities such as nuclear power control, railway facilities,
airline facilities, vehicles, combustion equipment and medical equipment are required.
-Applications in life critical situations
Please contact a Mitsubishi distributor for more information.
α2 Series Controllers is not designed to be used in the following applications:
1.1Special Features Display messages and Function Block data
1 ) Display messages and Function Block data
The
α2 Series can display the state of operation and the alarm on the LCD screen as a
message. The values of timers and counters can be changed in RUN mode.
-Total characters on LCD display: 12 characters x 4 lines
-Display items: Message, values (current or set) of timers and counters, analogue
values, etc.
2 ) Program Input
The user can program directly from the front panel or use the windows based
AL-PCS/WIN-E programming software Ver2.00. Pictorial representation of data is used to
connect function blocks. Please refer to the
α Software Manual.
3 ) Enhancement of clock function
The weekly and daily calendar timer function allows switch inputs that set the powerful
time dependent control capabilities.
4 ) Analog input, 0-10V/0-500
The DC input type for the
5 ) High Speed Counter, max 1kHz
The
α2 Series has two dedicated high speed counters when using AL2-4EX EI1 and EI2.
6 ) High current output
Relay output is 8A/COM in the main unit AL2-14MR-*: O01-6, AL2-24MR-D: O01-04 and
the transistor output is 1A/point in the extension module.
α2 Series accepts 0-10V signals with a resolution of 0-500.

7 ) GSM Function
The
α2 Series Controller uses GSM to send a SMS to a mobile phone or a dedicated
E-mail account via a standard service provider.
8 ) Dedicated Protocol
Introducing a Communication Device concept in the
user to monitor, modify and enter current and set values in Function Blocks via dedicated
protocol controlled from a personal computer.
9 ) Built-in EEPROM
The built in EEPROM eliminates the need for battery backed data.
10 )Supports 6 languages
The language option under the TopMenu can be changed to display: English, German,
French, Italian, Spanish and Swedish.

2.Function Block Programming
The α2 Series Controller is programmed with a user-friendly method of combining special
dedicated purpose function blocks. The task is broken down into various stages which can be
represented by a number of function blocks. Function Block Programming simplifies
application representation but ensures complete process control. The program can be
developed in very simple steps but even a complex task can be represented in this way. For
ease of use, the function blocks have been preprogrammed to perform certain tasks yet offer
flexibility to be tailored to individual requirements.

OS - One Shot Function Block
The user can build a complex circuit in small easy steps by starting at the input and working
forward in a logical manner. The
α2 will gather and process information and provide the
necessary control for the application according to the system algorithm. Each individual
function block provides specific control parameters, accessible by the user, to tailor each program for complete application suitability. The function blocks are connected together to form a
circuit using the Function Block Diagram (FBD.)

There are seven sets of items that can be used in the function block program: Inputs, Front

Blocks and Outputs. A brief description of each follows.

2.1.1Inputs
The α2 Series Controller will accept both digital (On/Off) and analog (mV value based)
electrical information through the system Inputs. Please refer to the
electrical information, wiring diagrams and input specifications. Depending on the chosen
controller there are either 14 or 24 input version types of the

2.1.2Front Panel Keys
The front panel keys can enter data into the program memory, move through menus or
programs, select programming options, or be used as extra inputs when the program is
running. There are eight keys which are referenced as K01 - K08.

These System Memory Bits can provide predefined signals - Always On, Always Off, 0.5
second On, 0.5 second Off, or provide information about the Real Time Clock time or errors
etc. There are fourteen Memory bits that are referenced to M01, M02, ... M14.

“ON” when Stop mode turns to Run mode in the α2 Series. The “ON” signal acts as a
pulse output and then turns “OFF”.
“OFF” when Stop mode turns to Run mode in the α2 Series. The “OFF” signal acts as
a pulse output and then turns “ON”.

2.1.4Function Blocks
Programming the α2 Series Controller is based upon the combination of different function
blocks. They process the information received from the previously mentioned inputs and
control the system Outputs. They can also provide input signals or information to other
function blocks using word outputs pins. To make programming easier, the Function Blocks
have all been preprogrammed. Therefore, parameters within each function block dialog box
can be set according to the intended application. There are 38 Function Blocks available, they
are described in detail throughout Chapters 5 and 6.

2.1.6Function Block Diagram (FBD) base
The Function Block Diagram provides the base for which all programming actions for the α2 is
performed. Both the
FBD base contains a Title rectangle on the top, Input rectangles on the left and Output
rectangles on the right. The FBD base is also known as FBD wiring area. All the components
should be placed only within the FBD base rectangle except for the input and output signals
which can be placed in the FBD wiring area or in the Input or Output rectangles.

2.2Programming Methods
2.2.1Direct Programming
Direct Programming uses the keys on the front panel to create the program and enter any
required data values. The method for Direct Programming is explained in this manual
beginning at Chapter 4.
2.2.2AL-PCS/WIN-E Programming Software Ver 2.00
This windows based software allows the user to drag and drop the desired Function Block
icons onto the FBD base and construct a program. The program is downloaded to the
controller via the AL-232CAB cable. The visual on-screen connections make the software
easy to grasp for beginners and experienced users alike. The AL-PCS/WIN-E Programming
Software is fully explained in the
