Abstract:
An apparatus for transmitting a position detection signal of a multi-shaft motor whereby a parallel-form detection signal that is output from position-detecting devices disposed on each of a plurality of motors and used for indicating a motor rotation position can be transmitted to motor drivers for controlling the driving of the motors via a group of a small number of wires. In the apparatus for transmitting a position detection signal of a multi-shaft motor, a transmission-side converter converts a parallel-form detection signal from rotary encoders to a serial signal and presents the resulting signal to a reception-side converter via a serial signal transmission path. The reception-side converter returns the received serial-form detection signal to a parallel-form signal and presents the signal to motor drivers.
Abstract:
A pressure measured by a load cell is converted into a digital signal by an A/D converter provided in an analog interface, and is processed by a digital filter provided in the analog interface. A sensor signal processed in the digital filter is transferred to a controller 10 for industrial machinery every transfer cycle via an optical fiber. A digital sampling cycle by the A/D converter is set to be shorter than the transfer cycle.

Abstract:
The invention provides a robot capable of synchronizing with other robots without raising costs, a robot system, and a robot control method. The robot includes a storage portion (11) in which an operating program for the robot is stored, a main arithmetic portion (12) for analyzing the operating program stored in the storage portion, a sequencer portion (13) from which a signal from the main arithmetic portion is output, a driving portion (14) for driving the robot to which the signal from the main arithmetic portion (12) is input, and a communications portion (15) for communicating with apparatuses connected to a network. In the robot, a signal input from an apparatus connected to the sequencer portion (13) and a signal input to the communications portion (15) are input to the main arithmetic portion (12) so as to perform a calculation, and, based on the calculation, a signal is output from the main arithmetic portion (12) to the sequencer portion (13) or to the driving portion (14).
Abstract:
An interface circuit includes a general-purpose CPU configured to transmit a clock to a serial encoder with which bidirectional serial communication of clock synchronization type is to be performed, the CPU being configured to transmit and receive data to and from the serial encoder; and an additional circuit configured to detect a start bit of reception data transmitted from the serial encoder. The general-purpose CPU starts counting the number of bits of the reception data in response to a detection signal from the additional circuit, the detection signal indicating the detection of the start bit. The CPU stops transmitting the clock to the serial encoder upon completion of counting a predetermined number of bits of the reception data.

Abstract:
A process control system includes a high speed serial backbone communications network, interconnecting a plurality of microprocessor based nodes that each act as the master to a high speed serial branch network comprising device controllers, such as air flow valve controllers and transducers. The primary network may operate in a time division multiplex mode whereby a node acting as a synchronizing station periodically issues a synchronizing signal that commands each node to execute a branch network control sequence, during which each node gathers and operates upon data it collects from the device controllers within its branch network, and issues commands based thereon to the branch network. An ensuing communications sequence also triggered by the synchronizing signal enables each node on the primary network to transmit a command or a response to any other node and, through such other node, to any device controller in any branch network of the system. Serial ports on each node permit user access from any node on the primary network to any other point on the system for purposes of monitoring and control. Serial ports on each device controller permit user access to local device parameters.

A multi-axis motion controller includes a digital signal processor operable in a standalone mode to run a motion control application program for controlling motion along multiple axes is organized in a shared memory architecture and includes a serial I/O data system with DMA access to the memory for repeatedly moving input and output data directly between the memory and a serial data line. The motion controller may be utilized in connection with a cup lid dispenser for an automated drinkmaker having a pivotable shuttle arrangement for dispensing the bottommost lid in a stack, and a double lid sensor for determining if more than one lid has been dispensed.
Abstract:
An apparatus receives a query from a process controller containing a process variable address representing a storage location for a process variable in a network of field devices. A communication standard type and an unique field device address is associated with each field device. An associating section identifies a field device address and a communication standard type associated with each of a plurality of process variable addresses. An extracting section matches the stored process variable address with a process variable address in the associating section and extracts the associated field device address and the associated communication standard type from the associating section. A generating section generates a field device request containing the extracted associated field device address as a function of the extracted associated communication standard type. The field device request is conveyable over a communication line to address the storage location represented by the stored process variable address.
Abstract:
Apparatus and method are provided for automatically controlling the position of one or more objects. The apparatus comprises a position control network which receives macro-type movement commands from a mainframe computer. The network includes a plurality of interface processors each adapted to provide a plurality of micro-commands in response to each macro-command. The micro-commands are supplied to motion controllers which in turn control the movement of servomotors. The servomotors position the object. Position encoders are provided to monitor the position of the objects and provide position data to the interface processor for transmission to the mainframe computer. A novel method is disclosed which employs the foregoing apparatus to provide synchronous motion of two or more objects.
