An accident monitoring system based on UWB-based real-time positioning comprises a UWB tag, a plurality of UWB anchors installed around a processing line and receiving the worker's position from the UWB tag and sensing predetermined information for the processing line, an AP receiving the worker's position and the predetermined information for from the plurality of UWB anchors, a server receiving the worker's position and the predetermined information for from the AP, storing the worker's position and the predetermined information for, and determining whether the worker is in a preset access-limited area, and a programmable logic control (PLC) box, upon receiving proximity information indicating that the worker is the access-limited area from the server through the AP, controlling to stop the industrial robot, the conveyor belt, and the motor in the processing line.

A collector included in a data collection apparatus performs data collection to collect data from a PLC. A controller included in the data collection apparatus determines whether the collector is valid depending on whether the collector at a time when an instruction to start the data collection is provided matches the collector at a preset time, and causes the collector to start the data collection in response to the collector being valid.

A method includes presenting a graphical user interface to a user, where the graphical user interface identifies multiple slots that are configured to be coupled to multiple input/output (I/O) modules. The method also includes receiving, from the user via the graphical user interface, information defining a slot assembly data map. The slot assembly data map identifies data offsets and data sizes associated with the I/O modules. The data offsets and the data sizes identify where data can be sent to or received from the multiple I/O modules over a single logical connection. The method further includes using the data offsets and the data sizes of the slot assembly data map to provide data to or receive data from one or more of the I/O modules over the single logical connection.

A programmable discrete input module is described. In one or more implementations, the programmable discrete input module comprises a pulse width modulation module configured to generate a pulse width modulated based upon an input signal and a pulse width demodulation module configured to generate a demodulated pulse width signal. An isolator is configured to isolate the pulse width modulation module and the pulse width demodulation module and to generate isolated modulated pulse width signal based upon the pulse width modulated signal for the pulse width demodulation module and to generate the demodulated pulse width signal. The programmable discrete input module also includes a first comparator and a second comparator for comparing the demodulated pulse width signal with a respective programmable reference and a digital filter configured to filter a comparison signal output by the first comparator or the second comparator to generate a discrete input signal.

A method synchronizes first and second simulation systems, each operating in a free running operation thereby exchanging data to run the simulation systems. The method includes: a) providing the first simulation system (PLCSIM) being enabled to run in cycles at a linear speed determined by repeatably setting a scaling factor (s.sub.n); b) providing the second simulation system (Process Simulate) to run in cycles at different speeds; c) the second simulation system requests at the end of a cycle a virtual time stamp from the first simulation system; d) calculating on the basis of the virtual time stamp a virtual duration time At.sub.nfs and on the basis of the virtual time stamp after completion of the cycle of the second simulation system a virtual duration time At.sub.nss; and e) calculating an update sn+1 for the scaling factor according the most recent scaling factor s.sub.n multiplied by At.sub.nss/At.sub.nfs.

An electric motor drive system is provided wherein safety is achieved by commanding the process system of the relevant axis or set of axes to execute motion that follows a defined path, namely trajectory of position, velocity and acceleration against time, re-constructing an identical trajectory in the safety system and in, the safety system, supervising deviations between the safely reconstructed target position and the safe measurement of position.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices. To charge, the machines employ electrical current from an external source. As demand at individual collection, charging and distribution machines increases or decreases relative to other collection, charging and distribution machines, a distribution management system initiates redistribution of portable electrical energy storage devices from one collection, charging and distribution machine to another collection, charging and distribution machine in an expeditious manner. Also, redeemable incentives are offered to users to return or exchange their portable electrical energy storage devices at selected collection, charging and distribution machines within the network to effect the redistribution.

A process control system includes a process controller level including at least one process controller, and an input/output (I/O) module level including at least one I/O module. The process controller level and the I/O module level are communicatively coupled. and each include control logic comprising control hardware or algorithm blocks. The control logic in the process controller level and the I/O module level are configured to execute and exchange data to perform process control for a process run by the process control system in a distributed fashion across the process controller level and the I/O module level.

Systems and methods for automated manufacture are provided. User input is received by way of user systems indicating nominal data measurements for an article. Automated material handling machines move parts within view of a machine vision system which performs an initial scan to identify features of said parts. Locations of areas for joining are determined by comparing the identified features to the nominal data measurements and the automated material handling machines move the parts into positions in accordance with the nominal data measurements to form the article. The automated material joining machines join the parts at said areas specified in said user input to form the article.
