Abstract
A reflex I/O card for an industrial controller receives enabling inputs from the executed control program and triggering inputs from an industrial process to provide outputs at a fixed delay in time or portion of a machine cycle after the inputs through dedicated hardware thus avoiding transmission delays and processing delays associated with the communication of information to a central processor and the execution of the control program.
Claims14
An industrial controller producing electrical outputs to control an industrial process based on the execution of a control program and the values of electrical inputs received from the industrial process, the industrial controller comprising:
- a) an I/O module including:
- i) an output terminal providing an electrical output to the industrial process;
- ii) a first and second input terminal receiving first and second electrical inputs from the industrial process;
- iii) a logic circuit within the I/O module receiving an enable signal from a central processor and the second electrical input to assert the electrical output upon the assertion of the enable signal and the second electrical input;
- b) a central processor communicating with the I/O module to receive the first electrical input and executing the control program to provide the enable signal based on the first electrical input and the control program;
- whereby the electrical output may rapidly respond to the second electrical input while remaining under the control of the control program.
