A cell control device of a production system includes a product information monitoring unit for monitoring the product information, a component supply state monitoring unit for monitoring plural kinds of components to be supplied to at least one cell and the number of each kind of components, and a notification unit which transmits a notice to a higher-level management controller when the number of each kind of components, which is monitored by the component supply state monitoring unit, deviates from a predetermined range determined for each kind of components.

Abstract: In a winding control method and device for a circular knitting machine, in a position control mode in which control is performed such that winding is performed in a winding amount corresponding to position control data, a winding control portion (6) changes production amount data in response to a change in specific knitting data which affects a production amount of the knitted fabric during operation, of the knitting conditions, and sets the position control data corresponding to the winding amount of the knitted fabric such that the position control data changes in synchronization with the change in the production amount data.

Abstract: A tuner receives broadcast data on specified channels. A channel search unit controls the tuner to search for available channels, and creates a channel map representing the available channels and a selection order thereof. A channel order setting unit changes setting about enabling/disabling of the selection and/or the selection order of the channels in the channel map. An operation input unit accepts a channel selecting operation of a user. When the user performs an operation for channel forward selection or channel reverse selection through the operation input unit, a channel switching unit changes the selection of the channel according to the channel map and causes the tuner to receive the broadcast data on the selected channel.

Abstract: Replacement of a signal address referred to in a sequence program is carried out by storing in advance, before-after replacement information which specifies the relationship between signal addresses before replacement and signal addresses after replacement in a format with a specifying of range. Based on the stored before-after replacement information, all the signal addresses to be replaced are searched for in the editing target sequence program or replacement target symbol information. Replacement of a searched signal address with a corresponding after-replacement signal address is executed in accordance with the before-after replacement information.

Abstract: A numerical controller is capable of foreseeing the occurrence of interference during operation of a machine and securely preventing the interference. An advanced position calculating section determines advanced time for the next interference check, based on an end time point of an interference check by an interference checking device and the sum of a time required for the interference check, a time required for communication, a time required for decelerating and stopping a movable part, and a predetermined float. If an interference checking device detects interference, the interference checking device delivers an axis stop signal the movable part.

Abstract: A servomotor in a numerical controller is controlled by automatically switching to either pressure control or position control in association with the command which is smaller from among a command obtained by performing pressure feedback control and a command obtained by performing position feedback control. When switched to pressure control while moving according to a movement command, the output of the movement command is terminated halfway, and the command in the next block is executed, and pressure control of the next command is immediately started. As a result, a wasteful time is eliminated, and a cycle time of the operation can be shortened.

Abstract: When a servomotor (control axis) is coasting and rotating in a servo-off state in which no current is applied to the servomotor, this servo-off state is switched over to a servo-on state in which current is applied to the servomotor, and a position control and a speed control are started. An actual speed in servo-on state is obtained in speed obtaining means by a position/speed detector. Position command means obtains a command movement amount using the actual speed as an initial speed. A position deviation amount corresponding to the actual speed is calculated, a command movement amount, a position deviation amount, and a position deviation amount remaining in a position deviation counter in servo-on state with the sign thereof reversed are added to each other as a command amount to the position deviation counter.

Abstract: A simulation data creation supporting device which facilitates creation of an input/output operation window when a sequence control program is simulated through operation using the input/output operation window. The simulation data creation supporting device reads out the configuration set-up information of an input/output unit that is stored in a controller. Input/output signal information (input/output address) is extracted from the configuration set-up information and added with a symbol and a comment of a preset input/output address. The input/output signal operative window configuration information is thus created.

Abstract: Disclosed is a numerical controller capable of foreseeing the occurrence of interference during operation of a machine and securely preventing the interference. An advanced position calculating section determines advanced time for the next interference check, based on an end time point of an interference check by an interference checking device and the sum of a time required for the interference check, a time required for communication, a time required for decelerating and stopping a movable part, and a predetermined float. Further, an advanced position of the movable part at the advanced time is calculated based on pre-read program data and is outputted to the interference checking device. The interference checking device performs the interference check at the advanced position. If it detects interference, the interference checking device delivers an axis stop signal to a motion command output section, thereby stopping a motion command and decelerating and stopping the movable part.

Abstract: When a manufacturer or a user desires to adjust a Braun tube, it is required to display a test pattern satisfying setting conditions of display modes on the Braun tube. To set the display modes of the test pattern, a plurality of horizontal synchronizing signals and a vertical synchronizing signal are generated by a timer circuit for each field. Also, display modes (for example, shape, position, size, color and luminance) of a type of characters having the same shape are set in an OSD circuit to set the display modes of the test pattern composed of the characters having the same shape. Thereafter, a composite video signal of the test pattern satisfying the display modes is produced on the basis of the horizontal synchronizing signals and the vertical synchronizing signal in the OSD circuit, and the test pattern is displayed on the Braun tube according to the composite video signal.

Abstract: A memory (1) stores a sequence program (1a) expressed in a step format. Execution control device (2) executes this sequence program (1a), thereby carrying out operation control on the side of a machine (3). Display control device (4) displays the sequence program (1a) on a display screen of a display device (5), and displays various commands inputted by means of a keyboard (6), in the form of menus. An operator specifies a step by way of the keyboard (6), and also commands to interrupt the execution of the sequence program by way of the keyboard (6). Thereupon, execution stop control device (7) stops the execution of the sequence program in the specified step.
