HI,

Just upraded to V12 basic from V11, Installed service pack 1

Loaded a V11 Project through V12 and right clicked the plc - recompile all.

However on compiling I am getting an error on some Networks, stating internal error contat SIMATIC customer support. The errors seam to relate to Datablocks, I have a variable Datablock3.Alarm1active(bool),

The network has -----(s) for the particular bool, which is showing in red

Has something changed in V12 where you cant use certain datatypes / settings in datablocks ?


Thanks in advance for any comments
