Abstract
A control system to reduce a load to a system bus by interconnecting a main controller and two or more peripheral controllers in the control system, and a method thereof. Different addresses are assigned to the main controller and the two or more peripheral controllers, respectively. The main controller and the two or more peripheral controllers, to which the different addresses are respectively assigned, are interconnected using one serial bus.
Claims31
A method of interconnecting a main controller and at least two peripheral controllers using a bus in a control system, comprising:
- assigning different addresses to the main controller and the at least two peripheral controllers, respectively;
- and
- interconnecting the main controller and the at least two peripheral controllers, to which the different addresses are respectively assigned, using one serial bus.
A method of communicating between a main controller and a plurality of peripheral devices each assigned a unique address and each connected to the main controller using a serial bus, the method comprising:
- transmitting data including a specified address to each of the plurality of peripheral devices from the main controller;
- and
- comparing the transmitted data to each unique address of the respective plurality of peripheral devices to determine which peripheral device to be operated.
A method of communicating between a main controller having a main address serial bus (ASB) having a unique address and a plurality of peripheral controllers each having a peripheral ASB having a unique address, the method comprising:
- transmitting data including a specified address from one of the main and peripheral ASBs;
- and
- receiving the transmitted data at each of the main and peripheral ASBs, and comparing the received data with each of the unique addresses of the respective main and peripheral ASBs to determine one of the main and peripheral controllers to be operated.
A method of interconnecting a main controller having and address assigned thereto and a plurality of peripheral devices, the method comprising:
- connecting a plurality of first peripheral devices each having a unique address assigned thereto to the main controller in serial using a serial bus to communicate small volumes of data having address information between the main controller and the plurality of first peripheral devices by comparing the addresses of the main controller and the plurality of devices with the address information of the data;
- and
- connecting a second peripheral device to the main controller using a parallel bus to communicate large volumes of data between the second peripheral device and the main controller.
A control system comprising:
- a main controller to which a unique address is assigned;
- and
- at least two peripheral controllers interconnected with the main controller using one serial bus, and each assigned a unique address.
A control system, comprising:
- a main controller comprising a main address serial bus (ASB) having a unique address and a central processing unit (CPU) to transmit control data to and receive status data from the main ASB;
- a plurality of peripheral devices, each comprising a peripheral ASB having a unique address assigned thereto to transmit the data to the main ASB using the unique address of the main ASB and to receive the control data from the main ASB according to the unique address of the respective peripheral ASB;
- and
- a serial line to connect in serial the main ASB with each of the peripheral ASBs.
A control system to communicate with a plurality of peripheral devices having addresses assigned thereto, comprising:
- an address serial bus (ASB) to communicate with each of the plurality of peripheral devices in serial according to the assigned addresses of the plurality of peripheral devices;
- and
- a control unit to control the ASB to transmit and receive data to and from the plurality of peripheral devices through the ASB.
A control system to communicate with a plurality of peripheral devices, comprising:
- a main controller having a unique address assigned thereto;
- a serial bus to connect the main controller to a plurality of first peripheral devices each having a respective unique address assigned thereto to transmit and receive small volumes of data to and from the main controller according to the unique addresses of the main controller and the plurality of first peripheral devices;
- and
- a parallel bus to connect the main controller to a second peripheral device to transmit and receive large volumes of data to and from the main controller.
