OPC Server for Web-IO and serial communication

• Error fixed: In exceptional cases certain packet sizes could cause the OPC server to crash
• Error fixed: With Web Thermometers the status BAD (last known) could be briefly displayed unnecessarily
• Error fixed: Web-Thermometer polling optimized
• Error fixed: Analog Web-IO polling could result in freezing of the second channel

• Count value detection when incorporating many Web-IO boxes

• Supports Web-IO 4.0 #57734

• HTTPS support
• The Properties dialog for I/O Server now also allows direct entry of a product number.

The main advantage is that "Identify" can now also recognize when a device has been reconfigured from HTTP to HTTPS (or the reverse).

• New mapping concept for Web-IO Analog and Climate data
• Updated and expanded online help
• Various internal optimizations/changes

If when or after starting the OPC client a message appears that no OPC servers are available, the system may be missing the required OPC core components. You can download these in Version 3.00.102 here and install them. Alternately you can always find the most current version in the download area of the OPC Foundation at https://opcfoundation.org (OPC Core Components x.xx Redistributable).
