Hello Kbv, PSC 7 offers a lot of addition analysis of the status of your plant. So if you use the channel block from the APL (for example Pcs7AnIn) and connect it to an input adresse of an SM-Modules or field devices the CFC chart will generate at the compiling with option "Generate modul drives" a connection to the modul or field devices and get the status from it. And to share the information about the plant state the APL block used for input and output STRUCTS. The first value of the struct is the parameter or signal and the second value is the signal status. You can get more information about the signal status here. With regards |

Hi Kbv, Try setting ACC_MODE to "0" on the MOD_D8_PN block and then to "1" again. Check the result and report back. |

Dear Kbv, I faced this kind of issue once before in PCS 7 V8.2. You may try to check software update on basic library. After I updated the library, the module fault.gone. Hope it helps. |
Please give me 5 stars Rating if my post is helpful for you. :) |
