connect motbus with a delfi application

[Bgeerts]

We have the following problem:

We use AV panels to create a man machine interface for a machine, in stead of this panel we are going to use a panelpc. We use a Modbus protocolWe would like to create a low cost connection using the modbus connector of our PLC and the rs232 of our panelpc. The panelpc will run a Delfi application. We don’t know if it’s possible.

Do we need a driver? And where can we find this driver.
If there aren’t any drivers, is it possible to encode the modbusprotocol so we can make our own driver??

The Plc we use is a Modicon Quantum.

Try an ActiveX component for runtime-free drivers:
Automated Solutions
or InGear .

Will cost you a little and save you a LOT of trouble.

edit: You can try before you buy. Download the software from the website, it will work for 30 days.

Take a look at http://www.automation-consulting.com/mbdrv/mbdrv.htm

Also, do a search on google on ActiveX and Modbus, there will be enough information

This is where you want to go.

They have a Delphi toolkit that will do RTU over serial. Runs on 9X/ME/NT/2K/XP, Borland Delphi 5/6, you get the source, free working demo, $99 bucks. Cheap.


Here's my google:
