    摘要： An improved system for handling events in an industrial control system is disclosed. A module in an industrial controller is configured to generate an event responsive to a predefined signal or combination of signals occurring. The event is transferred to an event queue for subsequent execution. The event queue may also be configured to store a copy of the state of the module at the time the event is generated. The event queue may hold multiple events and each event is configured to trigger at least one event task. Subsequent events that occur during execution of the event task are stored in the event queue for later execution. An event, or combination of events, may trigger execution of an event task within the module, within the controller to which the module is connected, or within multiple controllers.

    摘要： An interface circuit is provided for an Input/Output (I/O) module in an industrial controller to compensate for voltage generated by a bias current in a thermocouple. During a calibration routine, the interface circuit supplies two known bias currents to a thermocouple and measures a voltage generated across the thermocouple as a result of each bias current. The measured voltages and known current values are used to determine the resistance value of the thermocouple leads. Using two known bias currents provides for an accurate measurement of the resistance value of the thermocouple leads when the thermocouple is generating a voltage corresponding to the measured temperature. Either the I/O module or the industrial controller may determine a voltage resulting from the bias current applied to the thermocouple during operation as a function of the measured resistance and compensate the voltage measured at the thermocouple leads to accurately determine the measured temperature.
