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

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

greets

Support Questions / Writing value with modbusrtu function code 16
« on: November 06, 2014, 05:33:25 AM »
Hello,

I'm hoping that some one can help me a bit on the way

When i'm retreiving a value from a register i'm using this code:

Dim ValueM As String
        ValueM = ModbusRTUCom1.Read("l41557", 1)(0)
        BasicLabel1.Text = ValueM

Now i also want to be able to write to this same register.

I tried the folowing code but this won't work

ModbusRTUCom1.Write("L161557", "100")

Can some one please explain what i'm doing wrong
