Hi there! I´m working with PCS7 v6.1 where i usually get the following error message: “asynchronous PLC error entering state” and the cycle time is exceeded (see attached .doc file with the diagnostic screenshots). It even provokes the CPU stop... Most of the errors refer to the OB1 cycle time ?? (where i´ve only performed a call to the FC109, also attached) and sometimes an error related with an “OB request” referring to OB34 and OB35 is generated. Both OBs contain the whole program. Any well-known reason for this? If any program routine is wrongly programmed, shouldn't the cycle time be exceeded always? Is there any protective action to avoid that the CPU goes to stop in this situation? Thank you very much in advance for your help and best regards, AttachmenterrorPCS7.zip (231 Downloads) |
