  • Risk evaluation support device, program product and method for controlling safety network risk evaluation support device
    Patent number: 7840430
    Abstract: A risk evaluation support device is used for a safety network which serves to cause an output device to make a controlled device operable based on a detection signal outputted from an input device when the input device detects a safety condition. The support device creates a parameter setting table for correlating a danger source with the input and output devices and a PLC for risk evaluation based on configuration data of the safety network obtained through a communication part and device data on devices obtained from a component database. Operating data for the safety network are obtained according to conditions provided by the parameter setting table and a current risk evaluation value for the danger source is calculated based on the obtained operating data. The calculated risk evaluation value is outputted to a display part.

  • ELECTRIC CURRENT SUPPLY CONTROL APPARATUS FOR GLOW PLUG, AND GLOW PLUG AND ELECTRIC CURRENT SUPPLY APPARATUS CONNECTED TO THE GLOW PLUG
    Publication number: 20100292908
    Abstract: An electric current supply control apparatus for a glow plug, and glow plug and the electric current supply control apparatus connected to the glow plug. In a transition state in which the load acting on an engine increases such as at the time of acceleration (S14: YES), an instruction signal which instructs increasing of an EGR amount is transmitted to an ECU (S18). Further, electric current is supplied to a heat generation resistor of a glow plug through resistance PI control (S20), whereby the temperature of the heat generation resistor is stably maintained at a target temperature, and stability of combustion is enhanced. Thus, even at the time of acceleration, generation of NOX can be suppressed effectively by increasing the EGR amount without lowering the engine output.

  • I/O UNIT AND INDUSTRIAL CONTROLLER
    Publication number: 20100235682
    Abstract: This invention enables setting of a diagnosis algorithm of a safety device to be easily carried out. A slice I/O unit stores a plurality of diagnosis algorithms each corresponding to a different safety device in an ASIC, and stores specifying information for specifying a diagnosis algorithm to use of the plurality of diagnosis algorithms in a register of the ASIC. The slice I/O unit performs diagnosis of a connected safety device using the diagnosis algorithm specified by the specifying information stored in the register of the plurality of diagnosis algorithms. The diagnosis algorithm to use can be selected by selecting a number, and the like, which is preferable as a setting process at a setting tool device can be facilitated and a human error does not occur.
