Benefits of technology

[0007]The systems of FIGS. 1, 2A, 2B do not provide a truly fault tolerant system in that the certain components are not redundant. Thus, if any single component fails at least a portion of the system and / or devices connected thereto are offline until a repair can be made or system functionality can otherwise be restored. A need has been identified for an I / O system that avoids this single-point failure outcome for certain applications including many industrial automation control applications, such as distributed control systems for process and plant control where continuous and uninterrupted operation of the controlled process or system is a critical requirement. In addition, such a system should allow for easy configuration of redundant components (e.g., a pair of I / O modules operating in simplex vs. a pair of I / O modules operating in duplex).

Problems solved by technology

The systems of FIGS. 1, 2A, 2B do not provide a truly fault tolerant system in that the certain components are not redundant.

Embodiment Construction

[0031]FIG. 3 shows a distributed modular I / O system 110 in accordance with an embodiment of the present development. As described in detail below, the system 110 includes terminal block assemblies that permit an I / O base to operate in simplex mode, duplex mode or a combination thereof, as desired.

[0032]The distributed modular I / O system 110 includes a network adapter 112 that is operatively connected to both first and second redundant industrial automation networks N1,N2 such as first and second Parallel Redundancy Protocol (PRP) LAN networks or the like such as an Ethernet / IP network or other industrial automation network so that the network adapter 112 receives data from, transmits data to, and otherwise communicates with one or more industrial control modules or “controllers” C1,C2 connected respectively to the networks N1,N2. The controllers C1,C2 can comprise one or more programmable logic controllers (PLC), microprocessors, and / or other electronic processors for machine and / or...

Abstract

An I / O device includes an I / O base, at least two I / O modules supported on the I / O base, and a duplex terminal block assembly supported on the I / O base. The at least two I / O modules include a first I / O module and a second I / O module coupled to the duplex terminal block assembly in parallel. The duplex terminal block assembly can include connectors for connecting to a field device. The duplex terminal block assembly can include conductive structures for coupling the connectors with each of the first and second I / O modules. The duplex terminal block can be installed in a pair of ports in an I / O base to connect two I / O modules in parallel.

Description

FIELD[0001]The present development relates to industrial automation control systems and, more particularly, to a modular input / output (I / O) system having terminal blocks for coupling I / O modules to other components.BACKGROUND INFORMATION[0002]Distributed modular input / output (I / O) systems for industrial automation control fcsystems are well-known and in widespread use. Referring to FIG. 1, a known distributed modular I / O system 10 includes a network adapter 12 that is operatively connected to an industrial automation network N such as an Ethernet / IP network or other industrial automation network so that the network adapter 12 receives data from, transmits data to, and otherwise communicates with an industrial control module or “controller” C also connected to the network N. The controller C comprises one or more programmable logic controllers (PLC), microprocessors, and / or other electronic processors.[0003]The adapter 12 includes an adapter base 12a that is mounted to a DIN rail D o...
