So it is better to use CFC cross reference with the variables used in chartsĪlso the combilation shall be used according to what have you change taking into consideration that you cannot ignore the combilation of CFC and downloading from CFC download to be able to go online with charts and monitor their code Simatic manager general cross reference contains both variables used in blocks and charts but if you used it to go to a variable used in a chart it will go to this variable a block converted from CFC and not to its place in charts The cross reference of the CFC are for the CFC charts only, so if you are searching a used IO or another variable in CFC it is better to use it， while if you are searching for variables used in Blocks using the simatic manager general cross reference So which should be used or which process to follow in this case. In this case if we have to go online or download in CFC we must compile first. Sometimes we change DB and after that we have to check the block consistency to be sure that whole logic is correct and no red statement in the logic. Right click on blocks and click block consistency, compile all or compile. I checked both cross references are working and I can go online from both of these.Īnother question (this was the question I wanted to ask).
I have a very small logic in CFC F System (only required logic 9DI + 4DO used) and other logic in OB1. You have to use the Cross Reference of the SIMATIC Manager
