摘要： An apparatus and method are provided for preventing the runaway of the integral term of a proportional integral differential controller which is usable in a feedback system. An error signal is supplied to the controller by the feedback system. The controller produces a control variable output signal from the error signal. In accordance with the invention. the controller imposes a slew rate limit on the control variable output signal. Also in accordance with the invention, whenever the controller attempts to drive the control variable output signal to exceed the slew rate limit, the integral term associated with the controller is adjusted to a value which forces the control variable output signal to its slew rate limited value In this manner, runaway of the integral term associated with the controller is desirably avoided.

摘要： 30-GF-1025 A method is provided for configuring a programmable logic controller (PLC) wherein the PLC verifies that the actual I/O hardware configuration of the PLC matches an I/O configuration specified by the user prior to running a control program on the PLC. The I/O configuration supplied by the user is collected in a configuration information file. The match test between the actual I/O hardware configuration and the configuration file is performed both before the control program is run on the PLC and continuously during the execution of the control program. Depending on whether or not the user has set a fatal fault flag, if a mismatch occurs at any time between the actual I/O configuration and the requested I/O configuration in the configuration information file, then the PLC either issues a halt or continues to execute the control program while providing diagnostic/error message information to the user. Advantageously, any memory space in the PLC memory which is not needed to fill the demands of the I/O request in the configuration information file remains free for other PLC tasks.

摘要： The present invention is a communication unit for exchanging data. More specifically, the unit includes an initiator and a responder that exchange data with a single time base. In one embodiment, the initiator generates a time base output signal that is used for determining a multiple of the rate at which data will be transferred to the responder. When data is received from the responder, the time base signal is used to over-sample the data to determine the point at which the data from the responder is valid.

摘要： An apparatus (25) for controlling a high power laser beam for three dimensional operation consists of a mirror (26) and three linear servo-mechanisms (42,43) to tilt and to translate the mirror (26). The movement of the linear servo-mechanisms is controlled by a computer numerical control system or programmable logic controller.

摘要： A method is provided for configuring a smart module (75A) which is coupled to a programmable logic controller (15). The controller (15) includes an initial configuration file which specifies an initial configuration for the smart module. After power up and initialization of the controller, the initial configuration file is transmitted from the controller (15) to the smart module (75A). The initial configuration file is now designated a current configuration specified by the current configuration file. Module specific information which is stored in the module is then displayed (70) to aid a user in configuring the module using a programmer 60. The user can then modify the current configuration file in response to the module specific information which was displayed. This significantly simplifies the process of configuring smart modules for the user.

摘要： APPARATUS AND METHOD FOR MONITORING POWER A power monitor for determining real and imaginary power associated with one or more line signals samples a plurality of line cycles during an observation window to generate a plurality of voltage-current sample sets for each line cycle. The sampling of the sample sets is timed such that the voltage-current sample sets are taken at different relative time positions. The power monitor stores incoming voltage-current sample data in one memory area and concurrently analyzes sample data already stored in another memory area. Deletion of sample data is not permitted until transient analysis of such data is complete. In another embodiment, the power monitor includes a working data memory area coupled to the sampling circuitry such that the sample sets occurring during each observation window are stored in the working data memory area in interleaved fashion to simulate a single cycle of data. This power monitor further includes a transient data area, coupled to the sampling circuitry, for storing the sample sets occurring during an observation window in a non-interleaved or sequential fashion. Power analysis is conducted on the sample sets in the working data memory area unless a power transient is sensed. Upon sensing a transient, data from the transient data area is provided for analysis.
