回答:
If you click on "Help On Event" on the module information form, you get the following:
Possible causes:
S7-300:
A module was removed or inserted illegally.
· S7-400:
Failure of the module inserted/removed monitoring or error in interrupt servicing due to a defective module or due to removing or inserting a module illegally.
To correct or avoid errors:
Based on the system status lists, check the current I/O configuration detected by the CPU. Compare this with the existing configuration to see whether there are any defective modules.
· Bus error in the local or distributed I/O
To correct or avoid error:
To remove the error, you must switch the device off and then on again. If the error still occurs, check the bus connection and interface modules in the distributed I/O. Make a note of the HEX code marked as "Not user-relevant" in the detailed information for the diagnostic buffer entry and contact your manufacturer.
· This error can occur when an expansion device is switched off, for example, if an IM module is defective.
To Correct or Avoid Error:
Replace the defective module.
