Abstract
An I/O system having redundant removable and/or replaceable components. Each of the removable/replaceable components can be removed by displacement parallel to a common axis. An I/O device having an I/O base with a lock-out toggle to prevent installation of one or more I/O modules to the I/O base unless a ground screw has been secured to supporting structure.
Claims20
An I/O device comprising:
- an I/O base;
- at least two I/O modules supported in respective I/O module slots of the I/O base;
- at least two I/O module ethernet switches supported in respective ethernet switch ports of the I/O base;
- and
- at least one terminal block assembly supported on the I/O base;
- wherein each I/O module is electrically coupled to a respective I/O module ethernet switch and terminal block via the I/O base;
- wherein the at least two I/O modules, at least two I/O module ethernet switches, and at least one terminal block are each separately removably attached to the I/O base;
- wherein the at least two I/O modules operate redundantly in parallel with respect to each other;
- and
- wherein the at least two Ethernet switches establish and maintain redundant Ethernet backplane networks independent with respect to each other.
7 more elements
An I/O base for an I/O device comprising;
- at least one I/O module slot for receiving an I/O module therein;
- a fastener configured to be secured to an associated support to which the I/O base is mountable, the fastener movable between a first unsecured position to a second secured position;
- and
- a lock-out toggle supported adjacent the at least one I/O module slot of the I/O base, the lock-out toggle movable between a first position at least partially blocking the at least I/O module slot and a second position not blocking the at least one I/O module slot.
1 more element
A method of assembling an I/O device on an associated support comprising:
- placing an I/O base on the support;
- securing a ground fastener of the I/O base to the support;
- and
- moving a lock-out toggle from a first position blocking an I/O module slot of the I/O base to a second position not blocking the I/O module slot;
- wherein the securing the ground fastener includes moving the ground fastener from an unsecured position blocking movement of the lock-out toggle to a secured position not blocking movement of the lock-out toggle.
