In the present invention, one of a prescribed number of numerical values is set as a primary temporary address for each of a plurality of slave stations that transmit data to and receive data from a master station by using a transmission synchronization scheme over a shared transmission line. The master station successively designates all the numerical values that could possibly be set as the primary temporary addresses, and on the basis of the reply sent via a management data region from a slave station having a primary temporary address matching the designated numerical value, it is determined whether there is an overlap among primary temporary addresses.

After a different identification number is imparted to each slave station, the identification numbers are successively designated, the slave station having an imparted identification number matching the designated identification number transmits, via the management data region, a label that has been preset for the slave station and that is associated with slave station identification information with which the slave station can be identified to the master station, and an address which is assigned to each slave station is associated with the label.

In the present invention, one or more region boundary points are provided in a conductive wire path comprising two wires having a line voltage produced by a DC power supply, and at the region boundary points, when the line voltage continues to be less than or equal to a prescribed value for longer than a prescribed time, the conductive wire path is disconnected. At the one or more region boundary points provided in the conductive wire path comprising two wires having a line voltage produced by the DC power supply, since the conductive wire path is disconnected when the line voltage continues to be less than or equal to the prescribed value for longer than the prescribed time, the conductive wire path is disconnected once at all of the region boundary points if a short circuit occurs in the conductive wire path. However, subsequent continuous power supply causes the line voltage to return to normal and the conductive wire path connection to be restored starting from the region boundary point closest to the power supply, but the conductive wire path is not connected at the region boundary point of the region where the short-circuit occurred. Therefore, the region disconnected from the conductive wire path can be identified as the position where the short-circuit occurred.

Because this invention detects variation in the angle between the light reception surface and the optical axis using the difference between the light reception amounts in the light reception areas, the invention is capable of detecting deviation of the light reception element in relation to the optical axis even in a case where the optical axis is adjusted through the swinging of the light projector or light receiver. Additionally, because the direction that the light projector or light receiver is to be swung in is determined on the basis of the light reception amounts of the light reception areas and the determined direction is indicated by the indicator, it is possible to efficiently adjust the optical axis.

A start signal for initiating synchronization is transmitted from the control-side device via the transmission line. The control-side device and each of the slave stations locally and internally generate a virtual transmission clock based on the start signal. The period from the end of the start signal to the beginning of a subsequent start signal is divided in time into a plurality of periods corresponding to one cycle of the virtual transmission clock. The one cycle of the virtual transmission clock is divided in time into a first set period and a second set period. Data is extracted on the basis of a difference in current value between the first set period and the second set period.
One of a predetermined number of numerical values is set as a primary temporary address for each of a plurality of slave stations that exchange data with a control-side device by means of a transmission synchronization method via a common transmission line. All numerical values that may be set as the primary temporary addresses are sequentially designated from the control-side device, and on the basis of replies via a management data area from the slave stations for which the designated numerical values match the primary temporary addresses, it is determined whether or not any one of the primary temporary addresses is duplicated. A secondary temporary address is generated by adding a predetermined unique value to each primary temporary address that is not duplicated, and the secondary temporary address is set via the management data area to the slave station for which the primary temporary address constituting the secondary temporary address has been set. After the secondary temporary address is set, a formal address indicating a start position of a data area in an I/O data area allocated to each of the slave stations and a unique identifier that is different for each slave station are set for each of the slave stations by using the secondary temporary address. A unique identifier is designated in the management data area, and the presence or absence of a response from the designated slave station is detected.

One of a prescribed number of numeric values is set as a primary temporary address to each of a plurality of slave stations delivering/receiving data by a transmission synchronization system via a transmission line shared by a control-side device. In an inquiry step, all numeric values that can possibly be set as primary temporary addresses are sequentially designated from the control-side device. In a duplication determination step, determination is made as to whether a primary temporary address is duplicated, on the basis of a reply via a management data area from a slave station the primary temporary address of which matches a designated numeric value. In a secondary temporary address-setting step, a secondary temporary address consisting of a duplication-less primary temporary address and a prescribed unique value added thereto is generated, and the secondary temporary address is set via the management data area to a slave station to which is set a primary temporary address that constitutes the secondary temporary address. The unique value constituting a secondary temporary address is differentiated each time a primary temporary address is reset, and a different secondary temporary address is set to each slave station. The above steps are repeated until there are no more duplicate primary temporary addresses.

An assembly article management system capable of accurately ascertaining the end of service life of each of a plurality of drive devices, using a simple principle.

When an initial setting time has been specified by an input operation via an initial setting time input means, the assembly article management system stores the first operation time measured during initial setting, as a first initial operation time, stores the second operation time as a second initial operation time, and sends same to a master station. When other stations receive the transmitted data, being the measured first initial operation time and the second initial operation time, from the master station, the transmitted data is stored as the first initial operation time and the second initial operation time. The assembly article management system then determines whether or not there is an operation error, on the basis of a comparison between the first operation time and the first initial operation time or a comparison between the second operation time and the second initial operation time.

DEVICE OPERATION CHECK SYSTEM FOR COMMON POWER SUPPLY LINE
In a transmission line to which multiple devices are connected, this device operation check system checks for device operation errors resulting from a voltage drop in the transmission line, and switches the power supply voltage between two levels while allowing the devices to operate normally. Multiple slave stations that exchange data with a master station are connected to a common power supply line and are connected to each of multiple devices to be controlled. Further, when an operation command is received from the master station, operation detection input is received from an operation detection means of the controlled device, an operation signal for operating the controlled device is outputted, and, after a prescribed time has elapsed from output of the operation signal, a switch timing signal is outputted which prompts switching from a first voltage to a second voltage. Further, when a first operation error signal from a first comparison means of the local station or a second operation error signal from a second comparison means of the local station is received, output of the operation signal is stopped.
