Indraworks 14.22 TCP/IP variables do not seem to work on VR2104

[jacquesp]

I have a VEP40 (XPe/Win7e) and VR2104 HMI.The VR2104 display's and variables that are mapped(linked) to variables on the VEP40 via the TCP/IP interface.

Using Indraworks 14.20 this interfaceworks fine. However if I download the systemfiles via Indraworks 14.22 (14.20 compatibility mode) to the two devices and install the same projects, I somehow loose the TCP/IP link bewteen the variables, as changing them on one screen does not update the other. 

Note: the VR2104 project fails to launch when downloaded  via 14.22 (14.20 compatibility mode), I have to recreate the VR2104 in 14.22 (14.20 compatibility mode) for the VR2014 to display the default screen. The VEP does not have the same issue the project launches fine however I no longer seem to have the TCP/IP link between the variables on the VEP40 and the CR2104. I've stripped this down to a single screen project and 4 variables one of each type (Bool,Int,Real,String). All works fine with  indraworks 14.20 system files but consistently fails when downloading the 14.22 system files. Also noted the HMI projects created in 14.22 do not work when downloading them to the devices in 14.20 with 14.20 systemfiles.

I note for 14.22 there are some new security option for the communication settings on HMI devices. Do these need some setup aher than the default values?

In general there is no known problem on TCP/IP with IW14V22P17. Some general hints:
- You have to use the same version of WinStudio on both PC's
- You have to install the system files from IW14V22P17 on both PC's
- You have to convert the project from the old WinStudio Version to the actual Version (IW14V22P17)
- by converting the project the system verifies the project. Look at the messages you will get from the system
Yes, there are new security Options inside the newer WinStudio Version, but they have no impact on existing projects

Upgraded from IW14V22P4 to IW14V22P19 still experience the same issue.

- Data changes work from VR2104(server) - > VEP40 
- Making changes in the VEP40 screen do not reflect on the VR2104

Can you please calrify what you mean by
- You have to convert the project from the old WinStudio Version to the actual Version (IW14V22P17) ?
     -- The Device Version on both Screens are 14V20, do not have the option to change to 14V22
     -- If I create 2 new screens using device vesion 14V22 I do not get the data changes reflect in either direction
