But I have such problem: I need to access a tags defined in different instanses of functional block in PLC project. In this case multiplexing with absolute addresses works only if functional block created with the option "compatibility with S7-300". But using this option makes some restriction in tag usage, such as impossibility of saving in retentive memory only part of tags, the all tags automatically selects for saving if at least one check-box selected. What can you advice me in this situation. Thanks.
