Abstract
A method for providing communication between controllers in which fewer communication lines are needed. The controllers include a first controller functioning to feed at least first and second data signals into a second controller at a next step, and further to feed first and second abnormality signals into the controller at the next step when the presence of abnormalities is determined. One of the first and second data signals as well as both of the first and second abnormality signals are fed into the controller at the next step from the first controller through a common communication line.
Claims8
A method for providing communication between first and second controllers, in which the first controller functions to enter thereinto at least first and second data signals from first and second data output means respectively and then feeds the first and second data signals into the second controller at a next step, the first controller further functioning to determine whether there are abnormalities in the data output means on the basis of the entered first and second data signals, the first controller still further functioning to feed first and second abnormality signals into the second controller at the next step when a determination is made that there are abnormalities present in the data output means, the first and second abnormality signals representing respective abnormal states of the first and second data output means, wherein one of the first and second data signals as well as both of the first and second abnormality signals are fed into the second controller at the next step from the first controller through a common communication line.
A communication device used with first and second controllers, wherein the first controller is provided with first and second data output means having the function of feeding at least first and second data signals respectively into the first controller, the first controller functioning to enter thereinto the first and second data signals and then to feed the signals into the second controller at a next step in a state of the first controller being connected to the first and second data output means through first and second signal lines, respectively, the first controller further functioning to determine the presence of abnormalities on the basis of the first and second data signals, the first controller further functioning to feed first and second abnormality signals into the second controller at the next step when a determination is made that there are abnormalities present in the data output means, the first and second abnormality signals representing respective abnormal states of the first and second data output means, and wherein the second controller is connected to the first controller through first and second communication lines, the second controller functioning to enter thereinto one of the first and second data signals as well as both of the first and second abnormality signals, all of the signals being fed into the second controller from the first controller through one of the first and second communication lines, the second controller further functioning to enter thereinto the other of the first and second data signals which are fed into the second controller from the first controller through the other of the first and second communication lines.
A method for providing communication between first and second controllers comprising:
- the first controller entering thereinto at least first and second data signals from first and second data output means, respectively;
- the first controller determining whether there are abnormalities in the first or second data output means on the basis of the entered first and second data signals;
- the first controller for feeding first and second abnormality signals into the second controller through a common communication line when the determination is made that there are abnormalities present in the first or second data output means;
- and
- the first controller feeding one of the first and second data signals through the common communication line.
