Open Discussion / Modbus propertie/settings

« on: August 06, 2018, 09:49:49 AM »

Hi to you al,

Maybe it's a stupid question but i searched the forum for it and i can seem to find it.

I'm using the modbus rtu connection. this is al working just fine in combination with my Schneider servo drive :-) .

Is it possible to make/use dropdown textbox so we can do de settings/properties when the aplication is running.
and not that is starting up right away.

So baudrate, commport, speed......

Hope you understand my question

Support Questions / Calling the modbusRTU anywhere else then from the mainform

« on: December 04, 2014, 10:43:28 AM »

Hello to everybody,

I have a lot working now and....its possible to let the servo drive do positionings and reference as wel as speed and jog profiles.

Now i'm trying to build some own function ( with a class) ...... with normal functions there is no problems.
But what i would like to have is the possibility to use the modbusRTU from my own class.vb

How would i go about this.

Many thanks for your answer you guys

Ok,

Did some further testing with a clean solution.

When i put my servo drive in  setting 1 then i can make sense of it

0: HighWord-LowWord
1: LowWord-HighWord

The speed wich i'm reading is oke but the position i have to divide by 8 to get the correct answer.

tonight i wl do some more testing

Hello Archie,

There is no error while reading the large negative value's :-) thats a good thing.
unfortunally there isd a unwanted side affect.

With the previous version of advancedHMI i could read the actual position from my servo drive and display it.
With the latest version i can read the actual position but the value i get back is not right.

This is the same with the speed, the value is a 8 numbered value wich i can't covert or recalculate to the right speed.

I wil do some more testing to see if i can put my finger on the problem

Hi Archie,

I have tried but no luck.

I have used a blank advancedhmi solution, made the changes in the code
put in a modbusrtu with a basiclabel with plcvalue l47696

The parameter which i'm reading
_n_act (actual speed of motor)

INT32       CANopen 606C:0h
INT16       Modbus 7696
R/-

With it stopped at this line can you hover the cursor over "rawdata" to see what the values are.

Hi Archie,

I have tested the code but then al retreived values are zero "0" nothing works then anymore.


As for the raw data value;
-      rawData   Count = 4   
      (0)   255   Byte
                (1)   255   Byte
                (2)   255   Byte
                (4)   255   Byte

Hope this helps out

Hi Archie,

Thanks for the reply :-)

Made a small change to your code to get it to work

Code: [Select]

dataPacket.Add(x(3))
                    dataPacket.Add(x(2))
                    dataPacket.Add(x(1))
                    dataPacket.Add(x(0))
Now it works

Thanks
