Problems solved by technology

Another disadvantage associated with known systems is that failure of one of the I / O channels 22a, 22b, 22c in a particular I / O module 20 requires removal and replacement of the entire I / O module 20, even if the module's The same goes for the failure of only one of the channels 20
This is highly undesirable because replacing a single channel 22 of an I / O module 20 due to failure of the module would result in very high overall I / O module replacement costs

Abstract

An industrial automation input / output (I / O) module includes a body defining an internal space including a plurality of slots. A module backplane connector is connected to the body, and a primary backplane interface circuit board is located in the space of the body. The primary backplane interface circuit board is electrically connected to the module backplane connector and includes electronic devices configured to transmit data and power to and from an associated backplane circuit through the module backplane connector. Multiple individual I / O circuit boards are installed respectively in the plurality of slots of the body. Each of the I / O circuit boards includes electronic devices configured to provide a single-channel I / O circuit for input or output of data with respect to an associated field device. Each of the I / O circuit boards is electrically connected to the primary backplane interface circuit board when installed in a respective one of said slots, and each of the plurality of I / O circuit boards is selectively removable from its respective slot and from the internal space of the body for selective electrical disconnection of said I / O circuit board from the primary backplane interface circuit board.

Description

technical field [0001] The present invention relates to industrial automation control systems, and in particular to input / output (I / O) modules for such systems comprising a plurality of single-channel I / O subsystems, wherein the plurality of single-channel I / O subsystems The system is mounted in modular sub-racks so that individual I / O channels can be installed and removed as required without affecting all other I / O channels of the module. Background technique [0002] figure 1 A first example of an industrial control system CS is shown, wherein the industrial control system CS includes an industrial automation controller 100 and a distributed industrial automation input / output (I / O) system 10 operatively connected to the industrial controller. I / O system 10 includes a network adapter module 12 that provides a connection 14 to an industrial data network 16 . Data network 16 may be any of a number of industrial control or I / O networks, including but not limited to ControlNe...
