Why can't my WebConnect find the SComm driver?

FAQ #101127

 

How to find out whether WebConnect knows about the SComm driver?
If you can not select e.g. "Ether-S-Bus (SComm)" as communication driver as "Connection Type" in WebConnect (see below), your WebConnect can not find the SComm:

If "Ether-S-Bus (SComm)" is available, the WebConnect found a running Scomm:


When does the WebConnect need the SComm driver?
The SComm driver is required if one of the following questions has to be answered with "Yes":

• Is a USB connection to the PCD system required?
• Is a Modem connection to the PCD system required?
• Is there an other application (PG5, OPC Server or Visi+) using the same serial communication port (e.g. RS232) in parallel to the WebConnect software?

Where does WebConnect look for the SComm driver?
WebConnect 2.0.x.x. checks the following 3 Registry entries and looks in the locations where the value of the entry is pointing for the SComm driver:

• My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\SAIA-Burgess\PG5\2.0\Global\AppsDir
• My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\SAIA-Burgess\PG5\1.4\Global\AppsDir
• My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\SAIA-Burgess\SAIA Communication Driver\1.4\Global\AppsDir

For checking whether these entries exist, open the Windows Registry Editor by selecting "Run..." from the Windows "Start Menu" and typing "regedit".

What to do if I don't have a SCommDll?
In case on your PC there is no Scomm installed (which is the case with a stand-alone installation of WebConnect 2.0.16.4), please install the last version of the SBC.Net WebConnect (which can be found on the support site under Software --> WebConnect or on the PG5 Controls Suite CD). Please first uninstall the previous version and then install the last version.
