Abstract
A logic controller formed by self-contained device modules plugged onto a DIN rail and onto a backplane contained in the DIN rail, the modules variously comprising a power supply, a logic control, I/O devices and gateways, each I/O device having microprocessor power, and the modules having a sliding lock movable into position adjacent DIN-rail-engaging flexible tabs to block deflection of the tabs and removal of the module from the DIN rail.
Claims11
Logic control apparatus comprising:
- a DIN rail mounting channel having an elongated base, fowardly directed walls along opposite longitudinal edges of said base, and co-planar flanges extending outwardly along respective distal edges of said walls;
- an elongated backplane assembly carried by said DIN rail adjacent said base, said backplane assembly comprising a printed wire board having conductive traces thereon, and plug-in connectors attached thereto at longitudinally spaced intervals, said plug-in connectors being electrically connected to said conductive traces and projecting forwardly between said walls;
- and
- device modules attached to said DIN rail flanges, said device modules each comprising means securing said device module to said flanges, and a logic board comprising a backplane connector coupled to a respective said plug-in connector, remote device connector means, logic control means for processing electrical signals between said remote device connector means and said backplane connector, and a switch selectively settable for assigning a network address for said module.
