Abstract
The present disclosure relates to a method for managing a parameter of a communication-based master-slave control system, and has an effect of storing and applying parameters of all slave devices in a non-volatile memory in a master device, thereby enabling the slave devices to be set-up in a position where an operator is difficult to access or dangerous by a parameter stored in the master device, thereby simplifying maintenance of the slave devices and ensuring safety of a user.
Claims7
A method for managing a slave parameter, wherein the method is performed by a controller comprising one or more processors and memories, the method comprising:
- receiving parameters for all connected slave devices from a parameter setting device;
- storing the received parameters in a storage consisting of a non-volatile memory;
- requesting state information to the connected slave devices;
- and
- transferring the parameters stored in the storage to the connected slave devices when the connected slave devices require resetting the parameters, and are not occupied by another master device.
A method for managing a parameter of a master-slave system including a master device and one or more slave devices, the method comprising:
- receiving, by the master device, parameters for all slave devices connected to the master device from a parameter setting-up device;
- requesting, by the master device, slave device information to the connected slave devices;
- transferring, by the slave devices, the slave device information to the master device in response to the request;
- transferring, by the master device, a lock request to the slave device when the parameters for the received slave device are applicable according to the slave device information and the slave devices are not occupied by another master device;
- transferring, by the slave devices, a response to the lock request to the master device;
- transferring, by the master device, the parameters received from the parameter setting-up device to the slave devices when the received response to the lock request is acknowledge (ACK);
- and
- transferring, by the slave devices, a parameter reception completion response to the master device when the slave devices receive the parameters.
A device for managing a slave parameter, the device comprising:
- a controller including one or more processors and memories;
- and
- a storage consisting of a non-volatile memory for storing a parameter,
- wherein the controller is configured to receive parameters for all connected slave devices from a setting-up device and store the parameters in the storage.
