MAIN BODY DEVICE, SLAVE DEVICE, AND PROGRAM UPDATE METHOD

摘要

An update program is acquired in a main body device from an external device, a generation of noise from a noise generating source that has possibility to generate noise to a communication between the main body device and the slave device is suppressed, and after that, a slave device update program is transferred from the main body device to the slave device in the second communication method (second communication speed) which is faster than the first communication method (first communication speed).

主权项

1. A main body device configured to communicate with a slave device, the main body device comprising:
an acquisition unit configured to acquire an update program that includes at least a slave device update program for a slave control unit that is configured to control the slave device, from an external device; and a main body control unit configured to control the main body device; the main body control unit being configured to suppress a generation of noise from a noise generating source that has a possibility to generate noise to a communication between the main body device and the slave device, and subsequently transmit the slave device update program to the slave control unit in a second communication method that is faster than a first communication method, the first communication method being a communication method performed between the main body device and the slave device before the generation of noise is suppressed.
