Modbus Master ActiveX Control for Pocket PC and Windows
Using the Modbus Master control, you can easily read and write data from any Modbus Device using either the Modbus serial or TCP/IP protocols. The ActiveX control can be used with VB or VC for desktop development and eVB or eVC for Pocket PC development. This allows you to easily create your own simple HMI applications and is ideal for remote interrogation of PLC's using a PDA and serial cable or wireless link. The ActiveX control comes in three versions. One for desktop development, one for the Pocket PC SDK emulator and another for your Pocket PC device. Please note that the Pocket PC version of the control will only work on ARM compatible devices. The control works with both Pocket PC 2002 and Pocket PC 2003 devices. The control will allow you to interrogate upto 20 devices at once with upto 100 poll blocks for data gathering. The control works in both ASCII and RTU modes with both serial and ethernet connection settings easily configurable. Changes in remote data is event driven in your application so you do not need to constantly poll for data, you will be informed when any data within one of your poll blocks has changed. Data can be read and written in any one of 7 different formats which are :

Full diagnostic traces are also available via the EventLog. You can download an evaluation copy of the control by clicking here. You can see some sample applications developed using the control here. The cost of a single user development license for

for your own application, this is available at a cost of £250. If you wish to purchase a license or the source code, you can make a secure debit or credit card payment by clicking the
