Support Questions / Re: Access to specified bit in Holding Registers from Modbus Tcp

« on: October 09, 2014, 11:51:41 AM »

Thanks Arnie for advice with datasubscriber.

I was wondering is it possible to create datasubscriber instances with some litte code...
For example my program would read csv file with defined tag names and addresses for the tag, and also sometimes it would be defined specified bit in value register.
If tag will be definied with specified bit then one instanced of datasubscriber would be created.

I mean that I would like to periodically read some data and log some alarms if they occured.

Can I periodically read same datas from modbus in independent thread and in the same time all controls are updated periodycally ?

I do have a SimpleDataLogger component that is also in testing. It simply connects to a single register and can be set to write the data to a text file either on a time interval or on change of data.

The charting of data requires a few lines of code, but is very simple. In the data group of the Toolbox is a Chart control. You add a Chart and a Timer component to your form. Set the interval (milliseconds) on the timer in the properties, then double click the timer to get back to the code. This is an example of code to trend a data point:

Code: [Select]

Dim NewValue as string=ModbusTCPCom1.ReadSynchronous("40001",1)(0)
Chart1.Series(0).points.add(NewValue)


Where we can find SimpleDataLogger component ?
