1.1 Special Features of the
α
2SeriesSystem
1) Display message and Function Block data
The
α
2 series can display the state of operation and the alarm on the LCD display as a
message. It can display the following contents by the using display function block. The
value of displayed timers and counters can be changed in the RUN mode.
- Total characters on LCD display: 12 characters
×
4 lines
- Display Items: Message, value (current or set) of timer and counter, analog values, etc
2) The programming in the personal computer is fast and easy
The programming software AL-PCS/WIN-E for Windows can make and save programs.
The programming can be done using a pictorial method in which lines are used to connect
function blocks on a programming screen.
Direct programming using the
α
2 controller front panel keys is also available.
3) LCD image send via GSM modem
The
α
2 series is able to send the LCD image as an E-mail using a GSM modem. The user
can monitor application status by accessing the diagnostic message sent as an E-mail via
GSM modem
4) Supports computer link using dedicated protocol
The
α
2 series supports computer link (dedicated protocol). User-specific application

2 series can accept of 0 - 10V signals with a resolution of 0 - 500.
7) High speed counter, Max. 1kHz
The
α
2 series has high speed counters (Max. 2 points) when using AL2-4EX (EI1, EI2).
8) High current output capability
9) Built-in EEPROM
The built in EEPROM eliminates the need for battery backed data.
10)Supports 6 languages:
