Logic system employing modular logic cards - consists of several logic modules each associated with two interface cards

摘要

The modular logic card (1), for a logic system, has its surface (2) divided into a number of identical locations (4, 5, 6, 7), each carrying a logic module. Each location (4, 5, 6, 7) is associated with an internal interface card (8, 9, 10, 11), for direct linking with cards (12, 13) at the back of the mounting frame into which the logic card (1) is inserted. A second internal interface card (160, 161, 162, 163) is associated with each location (4, 5, 6, 7) for coupling to external connection cards (170, 171, 172, 173). Pref. each former internal interface card (8, 9, 10, 11) has a first section coupled to a parametric card (12) at the back of the mounting frame and a second section coupled to a bus card (13).
