3. Link Controller to Converter via twisted pair cable.
4. Or linked DSCAB connect cable.
5. Turn on the Controller’s power.
6. Open Utility and click Refresh COM ports to check PC’s com ports, then choose Controller’s COM port. And
click Search for modules to search Controller.

5
7. When correct to search Controller, Utility will show below figure. We can detect the Controller’s all com
ports’ parameters.
2.2 A1 series Remote IO module communicates with the PC
1. A1series Remote IO module build-in MODBUS RS-485 port, can via Converter to connect to PC. (Device
DATA+ connect to Converter DATA+, device DATA- connect to Converter DATA-)
2. Turn the Remote IO Module’s switch to ‘Init’ status.
3. Power on the Remote IO Module
4. Open Utility and click Refresh COM ports to refresh PC com port, and choose Remote IO Module’s
com port. Then click Search for modules to search device.
5. When correct to search Controller, Utility will show below figure. We can detect the Remote IO Module’s

6
parameters.
6. We can set the communication parameter as below figure. For example, DEC(ID Address)range is 1-255.
When finish the parameter setting, can press Update to save the setting.
7. Or can click Digital Output to test device hardware’s LED indicator.

7
8. Remote IO Module via MODBUS RS-485 to communicate to other devices (PLC, HMI, Data Logger, etc.). To
communicate fail warning, we can set related notify in Comm. Fail Safe. When finish it, press Update to save. Or
can click Restore to restore device’s current data.
9. When turn on the Remote IO Module’s power, can set the power on output indicator via Power On Digital
Output. When finish it, press Update to save. Or can click Restore to restore device’s current data.
10. When complete above setting steps, turn the Remote IO Module’s switch to ‘Normal’ status and re-turn
on the power can finish the setting.

3.2 Properties-General
In this tab, you can enter detailed information of a circuit program.

10
3.3 Properties-Parameter
Program Name
A program name with up to 16 characters can be entered in the circuit program.
Program Password
A program password with up to 8 alphabetical characters can be assigned to protect the circuit program on
the controller. Enter 2 identical passwords in the New Password and Repeat New Password text boxes
separately to assign a new password for your circuit program. You can delete the assigned password by
leaving New Password and Repeat New Password text boxes empty.
You can open or edit the circuit program from Editor at any time no matter if the program is
password-protected or not. For password-protected circuit programs, you have to enter the password to
view or modify the program on the controller, or to load the circuit program from controller to Editor.
Redundancy
The controller provides redundancy to help you build a robust system. In case the server is going down
there is a backup server that can take over the job.
There are 3 types for you to choose.

11
None: Redundancy is not available for this type.
Master: Connected controller is the main controller of the whole system. It communicates with Slave
continuously.
Slave: Connected controller becomes Master automatically, if it doesn't receive signals from the Master
over a period of time which is defined in the Synchronizing time text box in milliseconds.
3.4 Properties-Protect
Copy Protect
When select this function, can protect program illegal download without the correct password.
Temperature Protect point
Set the temperature range. If work temperature surpasses the range, memory will record.

3.5 Properties-COM
You can set the following parameters.
Model: Master, Slave, ATP (A series text panel)
Device address: From 1 to 255 (for slave only)
Protocol: Modbus-RTU, Modbus-ASCII
Baud rate: 1200, 2400, 4800, 9600, 14.4K, 19.2K, 28.8K, 38.4K, 57.6K, 115.2K, 230.4K (bps)
Parity/Data bit/ Stop bit: None, 8, 1/None, 8, 2/Odd, 8, 1/Odd, 8, 2/Even, 8, 1/Even , 8, 2
Timeout: In millisecond
Delay between polls: In millisecond
Data register index: High Low, Low High

3.6 Properties-LCD Setting
You can place any image into the controller in *.bmp format (108*64).

14
3.7 Properties-Hardware
The device selection dialogue shows you which blocks and memory resources are available to you. Please
choose correct Controller type in this dialogue.
3.8 Communication Configuration
Choose a COM port from the list, if you know exactly which one connects to the controller. If you are not
sure which COM port connects to the controller, you can let Editor automatically detect the COM port.

3.9 PC -> Device
When complete the program, operate Tools -> Transfer -> PC -> Device to download program into the
controller. Or press Ctrl+D
3.10 Device->PC
If you would like upload controller program to controller, operate Tools -> Transfer -> Device->PC. Or press
Ctrl+U
3.11 RTC
This command can be used to read and set the date and time of connected controller, operate Tools ->
Transfer -> Clock Setting/Calibration
3.12 Summer Time and Winter Time
This menu command lets you set an automatic conversion of the summer and winter time for the
Calibration
(Sec/week)
Get : Read controller calibration value
Set : Save calibration value into the controller
Clock
Setting
Read : Read controller RTC date and time
Write : Save RTC date and time into controller
Current Time : Read PC’s current time and date

controller’s clock.
When you enable summer/winter time conversion, you can specify a country-specific time conversion:
*EU: European Union
*UK: United Kingdom of Great Britain and Northern Ireland
*US: United States of America
*Australia
*Tasmania
*New Zealand
*Freely adjustable: customized switch over dates and times
For the "Freely adjustable" selection, you specify the month and the day of the switch over. The start time
of summer time is 02:00 + the entered time difference; the end time is 03:00 –the entered time difference.
Note: The United States of America redefined the daylight saving time (summer time) / standard time
(winter time) switch over dates in 2007. Controller, however, uses the switch over dates as they were prior
to 2007. To use the new U.S. Switch over times, you must configure a “Freely adjustable” setting that
corresponds to the new rule where Daylight Saving Time is in effect from 2:00 a.m. On the second Sunday
in March until 2:00 a.m. On the first Sunday in November according to the local time zone.
3.13 Clear User Program and Password
In 3.3 Properties-Parameter mention about password protection. If you would like to clear the program

and password can use this function. Tools -> Transfer -> Clear User Program and Password
3.14 Simulation
Click on the Tools -> Simulation, or press F3or click
Simulation Toolbar
The simulation toolbar, which is shown as follows, is active when the program is in simulation mode. Use
this tool to perform the simulation
Simulation Control Icons
Time Control
For a time-sensitive circuit program, you can use the time control to observe the processes of the circuit
program. This is a simple but effective way to predict the result of the program operation.
