摘要:
A system for monitoring a variable output paper processing device is provided. The monitoring system includes a counter which counts the number of papers processed and provides a count signal for each counted paper. A controller receives the count signals and totals the counts. The controller transmits the total count to a central station through a modem after either a predetermined time or a predetermined count. Internal diagnostic signals in the printing device are intercepted as they are transmitted to an internal display device of the printing device and transmitted to the central computer through the modem.

An apparatus for automatically milking animals, such as cows, comprising a robotic mechanism, two computers each having a display screen and keyboard, the apparatus having a plurality of exchangeable parts provided with a signalling device to transmit information when an exchangeable part is malfunctioning, the signalling device also identifying the malfunctioning part on one of the display screens of a computer. An emergency electrical battery is provided at an individual compartment for milking an animal for providing electrical power in the event of failure of the main power, and a computer is provided for closing down non-vital functions in the event of such power failure or of malfunctioning of the part or parts concerned. The teat cups of the set of teat cups which are automatically installed and removed from the last animal being milked can also be individually installed manually on the animal's teats, and a second set of teat cups for similar manual installation and removal is also provided, including conduits for pulsating the teat cups of the second set connected to a vacuum source, and for conveying milk received in such teat cups to a receptacle.

摘要:
A system for monitoring a variable output paper processing device is provided. The monitoring system includes a counter which counts the number of papers processed and provides a count signal for each paper counted. A controller receives the count signals and totals the counts. The controller includes an internal clock as well as an interrupt signal generator. Upon receipt of the count signal, the interrupt generator generates an interrupt signal starting the internal clock. The internal clock has a duration of a predetermined value larger than random noise signals. The controller compares the internal clock signal to the count signal and determines whether a valid count has occurred. The controller includes a CPU and RAM which are coupled by a PAL which isolates the RAM from the CPU when a voltage supplied to the CPU and PAL falls below a predetermined level.

In aspects, the present invention discloses a method for replacing a first field device with a second field device using a commissioning tool. The method comprising retrieving a device description file associated with the first field device, analyzing the device description file, generating a first object by mapping a parameters of the second field device to a parameter from the identified one or more parameters based on a first index and a second index, generating a configuration file associated with the second file device based on the device description file and the generated first object, and transmitting the configuration file to the second field device for commissioning operation of the second field device. The step of analyzing the device description file comprises identifying one or more parameters from the plurality of parameters for mapping based on a predetermined criteria.
摘要:
A document production apparatus has a plurality of replaceable units and a diagnostic system for determining the condition of the replaceable units. A computer control system monitors and controls document production functions, and includes a display for providing instructions for error diagnostic sequences. A diagnostic microprocessor for processing diagnostic signals representative of document production device conditions, has data entries, outputs, and storage for diagnostic routines. Error isolation diagnostic procedures identify suspect replaceable units. The procedures include displaying (1) a list of symptoms from which a user can select the symptom which best describes a condition of the document production apparatus, (2) a stored list of suspect replaceable units which are associated with a selected symptom, and (3) the status of each suspect replaceable unit displayed. The list of suspect replaceable units are displayed in an order of the probability of defect.

A hierarchical distributive control system is disclosed. The lowest level of the system is a stand alone controller with hot plug in capability, which can accept either analog or digital signals, scale these signal with input subroutines, perform any one of a number of algorithms to produce control signals or can manually produce control signals and output these control signals as either analog or digital signals to field devices. A plurality of controllers communicates with an associated condenser over duel parallel digital communication buses with a full echo, verify communication routine. The condenser contains all records for all controllers under its supervision and can download control information into any replaced controller. A subhost is interconnected to a group of condensers and contains all records contained in all condensers under its supervision. All information can be uploaded from condensers to subhost or downloaded from subhost to condenser. In case of any failure in any subsystem, all lower level systems continue to operate. All controllers are interchangeable.
摘要:
A method and apparatus for detecting and analyzing errors in a communications system is described. The method employs expert system techniques to isolate failures to specific field replaceable units and attempts to restore the failing unit to service, if the system will not be adversely affected, by removing it from service, resetting the resource and returning it to service if it passes retesting. The expert system techniques include detailed decision trees designed for each resource in the system. The decision trees also filter extraneous sources of errors from affecting the error analysis results.
