Abstract
It is desired to be able to easily identify a cause of a communication abnormality in an industrial machine. A controller of an industrial machine which communicates with an external device through a network includes: a plurality of communication units which respectively correspond to a plurality of communication protocols; and a diagnosis unit which starts up the communication units in a predetermined order and attempts communication using the communication protocols corresponding to each communication unit that is started up so as to diagnose the conditions of communication step by step.
Claims8
A controller of an industrial machine which communicates with an external device through a network, the controller configured to execute a program and operate as:
- a plurality of communication units which respectively correspond to a plurality of communication protocols;
- and
- a diagnosis unit configured to start up the communication units in stages in an increasing order of complexity of the corresponding communication protocols, and attempt communication using the communication protocols corresponding to each communication unit that is started up so as to diagnose conditions of communication at each stage and identify the cause of a communication abnormality.
A diagnosis method performed by a controller of an industrial machine comprising:
- starting up, in stages in an increasing order of complexity of corresponding communication protocols, a plurality of communication units, which communicate with an external device through a network, the plurality of communication units respectively corresponding to the plurality of communication protocols;
- and
- attempting communication using the communication protocols corresponding to each communication unit that is started up so as to diagnose conditions of communication at each stage and identify the cause of a communication abnormality.
