Abstract
A control system includes a control apparatus functioning as a master, and plural slaves which are network-connected to the control apparatus. The control apparatus executes a first instruction to set specified identification information to a specified slave. In response to whether the specified identification information is successfully written, the control apparatus outputs information indicating whether a reboot of the specified slave is required.
Claims14
A control system comprising:
- a control apparatus comprising a processor functioning as a master;
- and
- a plurality of slaves which are network-connected to the control apparatus, each of the plurality of slaves comprising a processor, wherein
- the processor of the control apparatus is configured to:
- execute a first instruction to set specified identification information to a specified slave, and
- in response to whether the specified identification information is successfully written, output information indicating whether a reboot of the specified slave is required,
- wherein each slave, among the plurality of slaves, comprises a nonvolatile memory configured to hold identification information, and a volatile memory configured to hold the identification information set to the slave,
- the processor of the control apparatus is further configured to write the specified identification information to the nonvolatile memory and the volatile memory of the specified slave, and
- the processor of the control apparatus is configured to output an indication that a reboot of the specified slave is required, when writing of the specified identification information to the volatile memory of the specified slave is unsuccessful while writing of the specified identification information to the nonvolatile memory of the specified slave is successful.

- network-connect the control apparatus to a plurality of slaves, the plurality of slaves each having identification information;
- and
- execute an instruction to set specified identification information to a specified slave,
- wherein,
- in response to whether the specified identification information is successfully written, the processor of the control apparatus is configured to output information indicating whether a reboot of the specified slave is required,
- wherein each slave, among the plurality of slaves, comprises a processor, a nonvolatile memory configured to hold identification information, and a volatile memory configured to hold the identification information set to the slave,
- the processor of the control apparatus further configured to write the specified identification information to the nonvolatile memory and the volatile memory of the specified slave, and
- the processor of the control apparatus is configured to output an indication that a reboot of the specified slave is required, when writing of the specified identification information to the volatile memory of the specified slave is unsuccessful while writing of the specified identification information to the nonvolatile memory of the specified slave is successful.
