SAFETY AND PROGRAMMABLE LOGIC INTEGRATION SYSTEM

摘要

An integrating system incorporating a programmable logic module, input/output (I/O) modules connected to the programmable logic module, and safety device modules connected to the programmable logic module. The modules may be connected with one another with connectors on each module. The modules may talk to each other via a common communication protocol carried by wires in the connectors. The programmable logic module may monitor and/or control signals on input and output terminals of the I/O modules that are connected to the actuators and sensors in controlled equipment. The programmable logic module may control non-safety aspects of the safety devices and inputs and outputs of the safety device modules and be modeled and appear in a same context as the signals of the input and output terminals of the I/O modules. A programmable display may be incorporated by the integrating system.
