Abstract
A safety module for a programmable logic control system, wherein the safety module is designed as an assembly consisting of a plurality of modules with a plurality of function blocks connected through at least one internal bus and comprising at least one CPU and which can be connected through at least one interface to external sensors (and switches/buttons) and actuators (and optical/acoustic indicators and displays/monitors) for detecting at least one measurement signal, wherein the safety module operates in two channels and a self-test is implemented.
Claims6
A safety module (1) for a programmable logic control system (PLC), wherein the safety module (1) is designed as an assembly consisting of a plurality of modules (2, 3, 4, 14, 53, 54, 55, 62) with a plurality of function blocks (2-4, 12, 13, 17, 25, 26, 35, 36) connected through at least one internal bus (7, 7a, 8, 8a) and comprising at least one CPU (9, 10) and which can be connected through at least one bi-directional interface (5, 6) to external sensors (and switches/buttons) and actuators (and optical/acoustic indicators and displays/monitors) for detecting at least one measurement signal, wherein the safety module (1) operates in two channels and a self-test is implemented.
