3.4 HMI
3.4.1 Inputs
% IW0: Horizontal position of the clicked point on the screen.
% IW1: Vertical position of the clicked point on the screen.
3.4.2 Outputs
% Q0: On/off screen backlight.
% QW0: Po er of the display backlight.
On the EDT screens, the backlight is not adjustable. It orks properly on URT screens.
3.5 Po er supply
The board can be po ered either
alternating or continuous depending on the
po er supply that is elded to the board.
Note : the yello arning sticker is only
present on the board hen the alternating
(« alternatif ») current is chosen.
4. Standby
The standby is caused by the instruction:
AlimOff();
The alarm is caused by:
- Press the Wake up PB
- RTC (Time and date of the alarm must be programmed)
- By communication on the COM3 (be a are that a simple polarization of the line causes
the alarm, the 0v must be connected)
Code for programming and activating the date and time of the alarm:
Date d;
long t
t = … ;
d = timeToDate (t);
stRtcAlarm.cSeconde = d.sec;
stRtcAlarm.cMinute = d.min;

stRtcAlarm.cMois = d.mon;
RtcWriteAlarm (KB_TRUE);
Code to turn off the date and time of the alarm:
RtcWriteAlarm (KB_FALSE);
5. Saved variables
There's a saved RAM. This allo s to manage histories.
6. Choice of target
In MicroLADDER, once the system code is imported, the target must be chosen. There are
4 target types for the MicroARM-A9: µArm A9 A (7"), µArm A9 A (4"3), µArm A9 B (7"),
µArm A9 B (4"3).
The choice bet een version A and B is based on the memory that is mounted on the
board. In version A, there are 16 MB of video RAM (IC10 in the top right has the reference
48LC8M16A2) and 512 KB of saved RAM (only U2 in the upper right is present). In version B
there are 32 MB of video RAM (IC10 in the top right has the reference 48LC16M16A2) and
1024 KB of saved RAM (U1 and U2 in the top right are present).
The choice bet een 7 " and 4 "3 is based on the size of the screen.
. Safety and warnings
If the device is not used as per these instructions, the safety of people and
equipment can be compromised. We disclaim any liability for any material
damage or due to improper handling or failure to comply ith the safety
instructions.
The interventions on the devices must be made by staff ho are competent to ork on
electric installations.
Before all interventions, all po er supplies must be s itched off. The cutting devices on
the installation must be dimensioned and placed according to the standard UTE C
15-100.
For all interventions on a device installed on an electric installation, the Personal Protective
Equipment (PPE) as defined by the safety regulations on the electric installations must be
carried by the orker.
In the event of a failure or malfunction, the device must not be opened and must be
returned to the factory.

Direct current.
Alternating current.
This device is CE approved and complies ith the national and European
guidelines.
8. Protection device
Quick fuse protections must be positioned on the 24 volt continuous start feeding the
PLC. These fuses ill be sized according to the number of devices set in series behind the
start.
9. Elimination
Old electronic devices are recyclables goods that should not be thro n into the
trash can. If the device reaches the end of its life, it should be eliminated in
accordance ith the legal regulations in force to the recovery centres in your
municipality. Elimination in the household trashes is prohibited.
10. Cleaning
For cleaning, use a clean, dry, antistatic, lint-free cloth ithout corrosive products.
11. Technical features
