Control system with selectable reset circuit

A control system, comprising:

• control means for controlling an overall system, said control means generating and outputting a reset signal based on the occurrence of at least one reset-condition;
• and
• a plurality of input/output means for interfacing appliances, said plurality of input/output means being reset in response to the reset signal from said control means;
• wherein said control means includes:
• a switch for selecting whether or not the reset signal is outputted to said plurality of input/output means;
• and
• a reset circuit for directly outputting a reset signal having a “HIGH” level to said plurality of input/output means when said control means is set to output the reset signal by selecting said switch, and for not outputting the reset signal to said plurality of input/output means when said control means is set not to output the reset signal thereby changing the reset signal to “LOW”;
• and
• wherein said control means outputs a reset signal to said plurality of input/output means when power supplies of said plurality of input/output means are turned ON after power supplies for said control means or one of said input/output means have been turned OFF and then ON, so that the system can be reset and controlled.

A control system for controlling at least one separate device through an input/output interface, said control system comprising:

• a central controller having a reset circuit which generates a reset signal based upon the occurrence of at least one predetermined condition, said reset circuit including:
• a switch for selecting whether or not the generated reset signal is to be outputted to said input/output interface;
• and
• said control system further comprising:
• a backup central controller which controls said device at a time when said central controller does not control said device;
• and
• a bus switch connected to said input/output interface, said central controller, and said backup central controller, said bus switch operative to select between and connect one of the central controller and the backup central controller to the input/output interface;
• wherein the selection in said central controller is overridden so that said generated reset signal is output to said bus switch.

A control system for controlling at least one separate device through an input/output interface, said control system comprising:

• a central controller having a reset circuit which generates a reset signal based upon the occurrence of at least one predetermined condition, said reset circuit including:
• a switch for selecting whether or not the generated reset signal is to be outputted to said input/output interface;
• and
• said control system further comprising:
• power supplies for providing electrical power to said controller, said input/output interface, and said device;
• a second circuit operable to ensure that said reset signal can be output to said input/output interface even while one of said power supplies is being reset.

A control system for controlling at least one separate device through an input/output interface, said control system comprising:

• a central controller having a reset circuit which generates a reset signal based upon the occurrence of at least one predetermined condition, said reset circuit including:
• a switch for selecting whether or not the generated reset signal is to be outputted to said input/output interface;
• and
• said control system further comprising:
• at least one power supply for providing electrical power to said controller, said input/output interface, and said device, said power supply outputting a power supply reset signal while resetting;
• and
• an input/output interface reset circuit operable to ensure that said input/output interface can be reset by said reset signal even during the time that said power supply is resetting.

A control system for controlling at least one separate device through an input/output interface, said control system comprising:

• a central controller having a reset circuit which generates a reset signal based upon the occurrence of at least one predetermined condition, said reset circuit including:
• a switch for selecting whether or not the generated reset signal is to be outputted to said input/output interface;
• and
• said control system further comprising:
• power supplies for providing electrical power to said controller, said input/output interface, and said device, each of said power supplies outputting a power supply reset signal while resetting;
• a second circuit operable to combine said power supply reset signals and said reset signal from said central controller reset said input/output interface when any one of said reset and said power supply reset signals is activated.
