I have a problem with a system that uses APP in and out between three modules, one MD4, two MC3. I have found that one MC3 does not appear to be receiving APPIN's. When I monitor the modules in IQAN Run, all modules appear to be talking successfully. When I look at IQAN Design the APPIN's on the module that's faulting says Error, Timeout and its red not green. On the module that's sending the APPOUT, the function block APPOUT is green and OK. Its almost as if the modules are not starting at the same time and the timeout for the first APP in to be received is being reached?
Is there any way of finding out more information about this error?
The machine was working OK for some time and it just happened randomly and now im unable to recover the machine. We also have other machines running this software and same software version and it appears OK.
I have extended the 50ms cycle time to 100ms,on all three modules with no success. Is there any reason why this could have happened? Running Design 3.19.9.
