An information collecting device controls a plant based on process data acquired from controllers and field devices connected to the controllers. The information collecting device includes an arithmetic controller and an update controller. The arithmetic controller collects first information which is engineering information of the plant and second information which is device information from a controller, a field device or a combination of both selected from the controllers and the field devices. The update controller generates third information based on a definition in which the first information and the second information are set in advance, and updates the third information in a storage based on a preset update cycle.

The present disclosure provides an industrial control apparatus that minimizes the increase in time taken for detecting a short-circuit in the apparatus and the decrease in the number of unoccupied terminals of a microcomputer due to detection of a short-circuit event. The industrial control apparatus includes first and second voltage supplying units, first and second circuits, an amplification command circuit, and a voltage amplifier incorporated into the first circuit. The amplification command circuit compares the input signal from the first circuit with that of the second signal, and if the comparison results in agreement, outputs to the voltage amplifier an amplification command signal indicating an amplification factor that allows a pre-amplified signal inputted to the voltage amplifier after being amplified to have a voltage out of the range of detecting connection or non-connection of the first input device to the first circuit.

A method for detecting a configuration of a modular safety controller includes generating a digital image of a module block of the modular safety controller, and evaluating the digital image with an evaluation device using image recognition. A logic code is generated which is compared with a plurality of configuration codes in order to determine the current configuration of the modular safety controller.
