GetCVStatus block is not allowing controller to get downloaded in 800xA 5.1 FP4.
I am using GetCVStatus function block in a non-SIL application in a 800xA 5.1 FP4 system. When I am trying to download, my controller is going faulty in middle of downloading sequence. What is the reason behind this? Any extension or rollup need to be installed to avoid this behavior? I observed this behavior inn 800xA 5.1 FP4 system alone, same block I have used in a non-SIL application of a 800xA 6.1 System. There it is working fine.
