A new updated OPC client Driver has been included in EasyPLC Software Suite.

The driver has been improved with automatic OPC Servers recognition in the computer where is running EasyPLC, also with the tree explorer, will be easy to add the connected variables without typing, only is needed to do drag & drop operations.

This updated driver is fully compatible with CODESYS, now you can create the logic of the programs whit CODESYS and communicate with EasyPLC & Machines Simulator to manage the logic of the virtual systems:

The driver is included from EasyPLC v5.9.5.A Setup intallation program, if you want to update it in yor system, please unload the attached zip file, unzip it and copy these files in the following paths:

OPCDriver.exe in -> C:\Program Files (x86)\EasyPLC\Drivers\  OR C:\Nirtec\EasyPLC\Drivers\

OpcComRcw.dll, OpcNetApi.dll, OpcNetApi.Com.dll and OpcNetApi.Xml.dll in -> C:\Program Files (x86)\EasyPLC\ OR C:\Nirtec\EasyPLC\

 - The old files must be overwritten
 - The paths 'C:\Program Files (x86)'  OR 'C:\Nirtec\EasyPLC\' are selected by default , your installation path could be different.

Problems solved:
-Real (float) values sent for analog signals now working correctly.
-When different number of analog I/O signals was present the software showed an error, now works ok.
