I am struggling with the following problem: We have a Momentum PLC running with a project downloaded from Concept 2.6. When I make a small change into the project and I download the change to PLC there seems to be no problem.

But when I try to run a visualisation project in Vijeo Look then after any click in visualisation the yellow triangles with red crosses appear over every object on the screen. We run OFS to enable communication between PLC and Vijeo Look. We use non-allocated variables in the project and probably the Visualisation does not work well with those unallocated variables after project changes. Can someone please describe steps which need to be taken to compile or upload a Concept project so that it works well in Vijeo Look with unallocated variables? Thank you, both answers are useful, I did not expect any answer so soon on such a specific subject.

I was searching OFS documentation but found no steps how to 'reload OFS server with the new project'. The Alias Properties has Symbols table file path, which points to the same PRJ file I have modified in Concept. Does it mean I have to upload some initial RAM directly from PLC to Concept after downloading project changes from Concept to PLC? Cannot find how to update OFS or where is the variables mapping stored. I have also found this advice, but not sure if it applies to my problem:Edited 2 Jul 2015 by vodoca. Hi vodoca, you understant this right.

In the OFS configuration you choose your PRJ file from Concept, so that OFS knows the variables names and their addresses. Does it mean I have to upload some initial RAM directly from PLC to Concept after downloading project changes from Concept to PLC? Cannot find how to update OFS or where is the variables mapping stored. Move from iphoto to picasa for mac. As I unterstand (I never used not allocated variables in Concept + OFS) just after some changes in Concept you save your Concept application as PRJ.

During restart of OFS, the OFS reads PRJ+VAR file to get new information about new addresses. Also this steps are necessary to let it work: - In the file c:windowsconcept.ini change the parameter ExportVariables = 0 to 1 -cc2cat.exe / RegServer.

I have recieved info from Schneider technician, that when PRJ is used that the VAR file is not necessary for OFS. I should turn on Dynamic Consistency & Check Device in OFS alias configuration. But the main problem seems to be the fact, that I have used Concept 2.6 to change & upload the project, but the project was created originally with Concept 2.5.

The best way to get from this OFS hell is to make all the variables located to specific addresses. I will need to connect to a spare PLC we have and test it in my office. Would you perhaps please suggest, what is the most simple way to power on this PLC using normal office equipment, like old power sources from switches, computers etc? So finally I had to setup test environment with a spare PLC modules.
