Abstract: An industrial wireless system includes a primary wireless node wire-connected to a first industrial device and a secondary wireless node wirelessly connected to the primary wireless node, and mediates data communication between a second industrial device and the first industrial device. The primary wireless node has a communication port that is wire-connected to the first industrial device, a communication port that wirelessly communicates with the mobile device, and a communication port that wirelessly communicates with the secondary wireless node. A first wireless network is constructed for wireless communication between the mobile device and the primary wireless node. A second wireless network is constructed for wireless communication between the secondary wireless node and the primary wireless node. The first wireless network uses a first radio frequency band. The second wireless network uses a higher second radio frequency band.

Abstract: A camera input expansion unit includes a camera-setting-information storage, a camera expansion processor, an image-recorder, and an image capture interface. The camera-setting-information storage stores setting information on the camera including the conditions of the image capture trigger. The camera expansion processor generates an ON/OFF signal for defining the image capture trigger based on the setting information of the camera. Based on the ON/OFF signal as the image capture trigger, the camera expansion processor acquires the image data which is generated by the camera. The image-recorder records the image data acquired by the camera expansion processor. The image capture interface is provided between the camera expansion processor and the camera. The image capture interface has an image-capture-trigger line propagating the ON/OFF signal to the camera and an image communication line propagating the image data generated by the camera to the camera expansion processor.
