Method for replacing a control unit in a conveying device
A method is disclosed for replacing a defective control unit in a conveying device interconnected by a bus. Conveying devices are used in logistics processes for fully automated and semi-automated conveying of goods by means of conveyor segments. These conveyor segments are controlled and monitored by control units. In order to minimize the downtime of the conveyor device, the described method for replacing a defective control unit in a conveying device interconnected by a bus can be used to ensure that a control unit can be replaced promptly and reliably. The method according to the invention allows automatic detection of a defect in a control unit, as well as initial configuration of a replacement control unit with an individual bus address or additional parameters.
Crash tolerant computer system
A computing device has access to a normal code execution environment and a suspect code execution environment. Suspect code data indicative of code that has been determined to be likely to cause a crash is accessed. Program code is executed using the normal code execution environment until suspect code as indicated in the suspect code data is encountered. Execution of suspect code takes place within the suspect code execution environment where a failure, if any, is contained. If the suspect code executing within the suspect code execution environment completes without failure, the resulting execution context is transferred to the normal code execution environment for continued processing. Otherwise, the suspect code is skipped and processing continues in the normal code execution environment. The code execution environments may be different cores of the same processor, different processors, or different devices.
