mental conditions!

2.2 Wiring

2.2.1 Overview

The picture belo sho s the backside connection layout of

the DMA-15.

Power supply and CAN connector:

1 +VDD positive supply (+7 to 32 VDC)

2 GND ground terminal (GND)

3 CANH CAN high terminal

4 CANL CAN lo terminal

ISP connector (for Programmer PG-30):

1 +3V3 positive po er supply (Pin 1)

2 GND ground terminal (GND)

3 SYS_SWDIO system data IO

4 SYS_SWCLK system clock

5 SYS_RESETN system reset (inverted)

2.2.2 Connecting the power supply

The DMA-15 features a ide supply voltage range from 7

to 32 VDC at very lo current consumption.

The DMA-15 can be integrated in battery supplied 12V

or 24V DC systems (cars, trucks, battery po ered cars,

forklifts and digger, for example).

Connect the supply voltage of 7 to 32 VDC to the 4-pole

terminal of the DMA-15. Wire the positive supply to the

‚+VDD‘ marked connection. The negative (ground) ill be

ired to the ‚GND‘ connection. All terminals may be used

ith a ire gauge from 0.25 to 1.5mm².

2.2.3 Connecting the CAN interface

The 4-pole connector of the DMA-15 also contains the

CAN-specic pins ‚CANH‘ and ‚CANL‘.

There is a 1k termination resistor integrated in the DMA-15

to ensure proper operation in direct connection to a backsi-

de-mounted BARTH® Mini-PLC.

Please refer to the appendix for detailed electrical spe-

cication of the CAN interface.

Ensure correct power supply voltage

range and polarisation! External fusing of

1A max. is mandatory! Disregarding may

cause irreversible damage of the DMA-15!

The voltage at CANH or CANL must not

exceed -32 or +32 VDC referred to ground

(GND). Higher voltages may cause irrever-

sible damage to the Mini-PLC!

Turn off the power supply before perfor-

ming any wiring operations!

Incorrect wiring, voltage reversal or

disregarding the electrical specications

may cause irreversible damage of the

DMA-15!

3Requirements for Operation

To operate the DMA-15 CAN display you ill need the

follo ing items:

1. The lococube® CAN Display DMA-15.

2. A mini-PLC ith a CAN interface (the lococube®

STG-800 is a good choice to get started and ill be

used in all our upcoming examples:

lococube® mini-SPS STG-800

3. A VK-16 cable is needed to connect the mini-PLC to

your computer:

Verbindungskabel VK-1 6

4. A cable to connect the CAN-Bus of the mini-PLC to the

one of the DMA-15. A KS-85 wiring harness, hich has

those connections already included can be found here:

Wiring harness KS-85

5. A resistor of 60Ω needs to be placed bet een the

CANH and the CANL connector of the DMA-15 and the mi-

ni-PLC. (You can omit this step if you‘re using a KS-85

wiring harness since it already includes those resistances).

6. A po er adapter to po er the mini-PLC and the

DMA-15 that supplies a voltage bet een 7 - 32 VCD.

(If you‘re using a KS-85 wiring harness you can plug in a

hollo plug ith these dimensions: Ø 5,5 mm / 2,1 mm).

7. A computer ith a Windo s operating system installed.

8. The miCon-L soft are hich can be do nloaded here:

miCon-L

9. The template programs hich can be do nloaded here:

Template Programs

4 Operation with miCon-L

4.1 Connecting the mini-PLC

Connect the mini-PLC to your computer. We‘ll be

using the loco-cube® STG-800. Plug the USB

connector of the VK-16 cable into your computer and plug

the other end into the mini-PLC into the TTL232 slot.

The orientation of the connector matters! Please orient the

connector, ith the little bump, facing left, as sho n belo .

Connect the CANH terminal of the mini-PLC to the CANH

terminal of the DMA-15 and connect the CANL terminal

of the mini-PLC to the CANL terminal of the DMA-15.

If you are using our KS-85 wiring harness, this can be

done simply by plugging the X1 connector into the mini-

PLC and the X2 connector into the DMA-15 or vice versa. If

you are not using a KS-85 wiring harness, make sure to

put a resistor of 60Ω bet een the CAN terminals! Plug in

the po er adapter and po er the mini-PLC

and the DMA-15.

1.4 Using miCon-L

Do nload and install the miCon-L soft are on your

computer. Do nload the template programs for the

DMA-15 here and place them at a location of your chosing:

After the STG-800 and the DMA-15 have been properly

ired up and connected, start the miCon-L soft are.

It‘s vital that you choose the correct serial port before you

continue into the actual programming environment!

No use the „folder icon“ in the top left hand corner to na-

vigate to the folder you have placed the template projects

in.

Navigate to the location you chose to put the template fol-

der in and open one of the projects using the .MDL le.

After you have succesfully opened the project of your

choice, there is one additional step that you must al ays

do hen creating or opening a ne project!

Go to Extras -> COM-Port Parameter.

This function block takes all the individual inputs, combi-

ning the into a vector, allo ing conversion ith a single

function block.

This is the „CAN-TX“ function block. It sends the data to

the screen of the DMA-15.

The input „Template Number“ has a global parameter of 3,

and sets the Template Number to 3.

Under that, e have the input „Value1“ hich is the number

set in program on the rst pin. By default it is set to 12345

and should display that on the DMA-15.

Belo that, e have the input „Value2“ hich corresponds

to the second pin in program. By default it is set to 23456

and should display that on the DMA-15.

After that, e have the input „Value3“ hich corresponds to

the second pin in program. By default it is set to 234 and

should display that on the DMA-15.

Lastly, e have the input „Value4“ hich corresponds to

the second pin in program. By default it is set to 123 and

should display that on the DMA-15.

And lastly, e have the input „Sho “ hich takes all the

combined inputs from earlier and sho s them on the actual

screen of the DMA-15.

Since this program only displays numbers and does not

receive any input, there is no need for „CAN-RX“ function

block.

5.4 Template 4 - Colored screen

Here e can see an overvie of the main program.

And the macro block „TEMPLATE4“.

The program sets all the inputs and parameters, and the

macro block is hat actually controls hat the buttons and

those parameters do.

Let‘s take a closer look at the program rst.

This part of the program makes the LED on the STG-800

blink every 5 s ith a 0.25 s long pulse. It‘s there to indicate

hether or not the program has successfully do nloaded

and is running correctly.

This part of the program has the three sliders. „blue“,

„green“, and „red“, and depending on ho you adjust those

sliders, the color of the screen ill change according to the

RBG values.

Next, let‘s take a look at the macro block.

The function block „CAN-CTRL“ is the CAN-Controller and

it needs to be included to set the baud rate of the STG-800

to that of the DMA-15. It does not need to be connected to

anything.

This function block sends a pulse in a 0.5 s cycle updating

the „CAN-TX“ function block.

Here, the three inputs from the program are called and

converted into the correct format.

This is the „CAN-TX“ function block. It sends the data to

the screen of the DMA-15.

The input „Template Number“ has a global parameter of 4,

and sets the Template Number to 4.

We have the inputs „blue“, „green“, „red“, hich corre-

spond to the inputs from the program.

The 2nd, 7th, and 8th input are not dened. but have a data

type associated ith them. They are needed to ensure the

correct message length of 8 byte ill be sent

to the DMA-15.

The button labeled „Refresh“ refreshes the screen in case

the DMA-15 did not update, after you‘ve started the pro-

gram. There are t o pins. One is called „Value“ ith the

global paramter 123456, and one called „Decimal Places“

ith the gobal paramter 0. The rst pin decides hat value

ill be displayed on the screen of the DMA-15 by default.

The second pin decides if there ill be a decimal point pla-

ced, and ho many decimal places there ill be.

The box called „Received messages“ displays the number

you‘ve entered on the touchscreen of the DMA-15, hen

you press „OK“.

Here e have an overvie of the screen layout.

This changes the number from positive to negative, and

back, hen pressed again.

Belo that, e have the keypad, ith numbers ranging

from 0 to 9, an „ESC“ button to reset the number back to 0,

and an „OK“ button that‘s used to update the „Received

message“ part of the program.

5.5 Template 5 - Keyboard

Here e can see an overvie of the main program.

And the macro block called „KEYBOARD“.

The program sets all the inputs and parameters, and the

macro block is hat actually controls hat the buttons and

those parameters do.

Let‘s take a closer look at the program rst.

This part of the program is just to make the LED on the

STG-800 blink every 0.25 seconds, as an indicator that the

program has successfully do nloaded and is orking pro-

perly.

In the next step, e ill take a closer look at the macro

block called „KEYBOARD“.

The function block „CAN-CTRL“ is the CAN-Controller and

it needs to be included to set the baud rate of the STG-800

to that of the DMA-15. It does not need to be connected to

anything.

These are inputs that call the pins from the program (as

sho n belo ), that ere mentioned earlier.

This is the „CAN-TX“ function block. It sends the data to

the screen of the DMA-15.

The input „Template Number“ has a global parameter of 5,

and sets the Template Number to 5.

Under that, e have the input „Value“ hich is the number

set in program on the rst pin. By default it is set to 123456

and should display that on the DMA-15.

Belo that, e have the input „Decimal Places“ hich cor-

responds to the second pin in program. By default it is set

to 0, hich means there there on‘t be any decimal

point placed at all.

The 4th and 5th input are not dened. but have a data type

associated ith them. They are needed to ensure the

correct message length of 8 byte ill be sent

to the DMA-15.

This is the „CAN-TX“ function block, responsible for recei-

ving messages. It gives a signal hen it receives ne data,

sho s the „Template Number“ in the box to the right, and

fetches the number you put in on the touchscreen of the

DMA-15. The t o not dened values are there because the

DMA-15 needs a message length of 8 byte. Even though,

they don‘t have a value set, they are assigned a data type.
