Industrial truck having an interface for diagnostic data
First Claim
1. An industrial truck having a first and a second controller (10, 18) each of which has a device for a self-diagnosis (16, 30) of sensors (12, 20) and actuators (14, 22) of the controller, comprising:
- one or more data lines (26, 28) between the first and the second controller for a transmission of operating and diagnostic data of the controllers wherein the operating and diagnostic data are transmitted on one or more interfaces with a common protocol, and a translation device (30) for diagnostic data of the first controller (10) for an interface (32) of the second controller (18) to which the diagnostic data of the second controller is applied, wherein the translation device (30) translates the diagnostic data of the first controller (10) into the same protocol in which the diagnostic data (24) of the second controller is applied to the interface (32) and both the interface and protocol are suited for exchanging diagnostic and operating data to communicate with additional controllers.

Abstract
An industrial truck having a first and a second controller, each of which has an apparatus for a self-diagnosis of sensors and actuators of the controller, including one or more data lines between the first and the second controller for a transmission of operating and diagnostic data of the controllers wherein the operating and diagnostic data are transmitted on one or more interfaces with a common protocol, and a translation device for diagnostic data of the first controller for an interface of the second controller to which the diagnostic data of the second controller is applied, wherein the translation device translates the diagnostic data of the first controller into the same protocol in which the diagnostic data of the second controller is applied to the interface and both the interface and protocol are suited for exchanging diagnostic and operating data to communicate with additional controllers.

17. A diagnostic apparatus for an industrial truck of the type having a first and a second controller (10, 18) each of which has a device for a self-diagnosis (16, 30) of sensors (12, 20) and actuators (14, 22) of the controller, the diagnostic apparatus comprising:
-
one or more data lines (26, 28) between the first and the second controller for a transmission of operating and diagnostic data of the controllers wherein the operating and diagnostic data are transmitted on one or more interfaces with a common protocol, and a translation device (30) for diagnostic data of the first controller (10) for an interface (32) of the second controller (18) to which the diagnostic data of the second controller is applied, wherein the translation device (30) translates the diagnostic data of the first controller (10) into the same protocol in which the diagnostic data (24) of the second controller is applied to the interface (32) and both the interface and protocol are suited for exchanging diagnostic and operating data to communicate with additional controllers, and wherein the diagnostic device reads out the diagnostic data of all controllers via the interface (32) of the second controller (18). - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
