Multifunctional input and output module for programmable logic controllers

摘要

Input and output module (1) for programmable logic controllers (PLC), wherein the module (1) is designed as an assembly (1), which by several functional blocks (2-7, 29, 30) as building blocks (2-7, 29, 30) is formed, which on the one hand via internal bus (10) and a CPU (13) are connectable and on the other hand via inputs and outputs (8, 9) with external electrical sensors (also switches / buttons) and actuators (also optical / acoustic Displays and displays / monitors) are connected, wherein on the module (1) any number of multifunctional building blocks (6, 7, 29, 30) are arranged, each multifunctional building block (6, 7, 29, 30) free by an associated Control module (12) is configurable, so as to form the respective functional block (2-7, 29, 30) as a multifunctional module (6, 7, 29, 30), characterized in that the CPU (13) externally outside the input and Output module (1) is arranged and via a likewise external to the outside - and output module (1) arranged system bus (11) data and control commands to the on the input and output module (1) arranged control module (12) transmits, wherein the control module (12) from the system bus (11) receives digital control signals, the Control module (12) tell which programming commands he should supply the respective multifunctional device (6, 7, 29, 30) to determine the function of this multifunctional device (6, 7, 29, 30), and wherein the control module (12) as Bus interface is formed, which is assigned a control logic, wherein the control module (12) controls the internal bus (10), and this internal bus (10) in turn via bidirectional data and control lines the respective multifunctional device (6, 7, 29, 30) accordingly, according to the selected function of the multifunctional module (6, 7, 29, 30) and the bidirectional inputs and outputs (8, 9) are controlled.
