Embedded controller and embedded controller development tool

摘要

PROBLEM TO BE SOLVED: To reuse interface software even when a part of control calculation means is changed in a built-in controller having the plurality of control calculation means, an input/output processing means, and the interface software exchanging data between the control calculation means and with the input/output processing means or the like.;SOLUTION: In this built-in controller, an interface means managing delivery or the like of a variable between the control calculation means or an execution instruction to the control calculation means from a control basic processing means is provided in each the control calculation means. When changing calculation logic of a partial control variable, it is possible to cope with the change by a change of only the corresponding interface software without requiring a change of the whole interface software, so that reusability of built-in software is improved.;COPYRIGHT: (C)2007,JPO&INPIT
