ClickPLC driver now failing after upgrade

[znelbok]

I upgraded to the last posted beta the other day and while the install went OK.

A day or two later the ClickPLC driver went off line and the logs indicate that the PLC address is wrong, sometimes its the wrong function in the reply.

Code:

09/21 20:42:24-Zeus01, CQCServer, CQCDrv_HousePLCThread13
{
    CQCGenDrvS, MEng.User.CQC.Drivers.Koyo.ClickPLC.DriverImpl.196, Status/App Status
    <SendMessage>: sent 8 bytes [01030000000EC40E]
}
09/21 20:42:24-Zeus01, CQCServer, CQCDrv_HousePLCThread13
{
    CQCGenDrvS, MEng.User.CQC.Drivers.Koyo.ClickPLC.DriverImpl.196, Status/App Status
    <GetIncomingData>: got 33 bytes [0001A98F01031C000A00140000001E000500000000000F004400140000159E0014]
}
09/21 20:42:24-Zeus01, CQCServer, CQCDrv_HousePLCThread13
{
    CQCGenDrvS, MEng.User.CQC.Drivers.Koyo.ClickPLC.DriverImpl.494, Status/App Status
    <GetIncomingData>: Wrong PLC Address received 0

I have not analyzed the data string yet to confirm the correct message is going out, but the PLC is responding so its going to be a valid message.

If I pause the driver and then restart it everything is good - the driver goes back on line and the driver is processing the data correctly.

Any ideas as to why this could be happening?
