The present invention relates to a method, device, and system for transmitting a program and parameter to a PLC. An adapter connecting to a port of a PLC allows an operator to simply (i) log in on a cloud server with use of a mobile terminal on which an APP is installed, (ii) download a written program or parameter, and (iii) transmit the program or parameter directly to the adapter wirelessly to transmit the program or parameter to the PLC via the adapter. An alternative embodiment may be arranged such that the cloud server transmits, to an APP of the mobile terminal over a mobile network, an instruction on what data to sample and that the APP accesses the PLC via the adapter, obtains the data, and feeds back the data to the cloud server. This simplifies the operation for updating and maintaining a program and/or parameter of a PLC and reduces costs.

A temperature detector (201) of an input unit (200) acquires a temperature of the input unit (200). A temperature detector (301) of an output unit (300) acquires a temperature of the output unit (300). When the temperature of the input unit (200) or the output unit (300) satisfies a preset condition, an input/output manager (101) of the CPU unit (100) controls passage/blockage of a signal from the detector (901) to the input unit (200) or a signal from the output unit (300) to a control target device (902) in accordance with preset content of signal input/output restriction.

A system and method for online simulation of a controlled machine or process utilizes a simplified model of the system dynamics and may be used with hardware in the loop to evaluate performance of the controlled system or with software in the loop to perform commissioning of the control program prior to completion of the mechanical installation. The simplified model includes dominant order dynamics of the controlled system such as the inertia of the system and a damping factor. Further, the online simulation is scheduled to execute at an update rate slower than the update rate of the control loops within the motor drive. The simplified model and reduced update rate reduce the computational burden on the processor such that the simulation may be performed either on the industrial controller or on the motor drive.

The objective of the present invention is to simplify the transfer of a program that has been edited. A support device, which assists in the development of a program executed by a target device provided in factory automation (FA), carries out a transfer process for transferring the program to the target device. The program includes a control program for controlling a machine and an HMI program for processing a variable used by the control program. When the control program or the HMI program has been edited, the support device simultaneously transfers the control program and the HMI program respectively to a control device and an HMI device.
