A data reproduction device (1) is a data reproduction device for plant-monitoring control system to be newly connected to an existing network 6 in which a packet is transmitted/received between a PLC (2) that is operating and an input/output device (3, 4). A setting information storing portion (10) stores setting information. A process data definition information storing portion (11) stores process data definition information. A process data acquiring portion (13) acquires a binary data array stored in the packet. A process data analyzing portion (15) decomposes the binary data array into a plurality of pieces of process data based on the setting information and, for each of the plurality of pieces of process data, associates one piece of the process data among the plurality of pieces of process data, packet receiving time, and the process data definition information to obtain one piece of process data analysis information.

A control and/or data transmission system for performing complex and elaborate calculations, includes at least one external data processing device directly connected to the control device. The outsourced calculations are performed by the external data processing device using a software module based on a trained artificial neural network. The results are then transmitted directly to the control device without any detours. For this purpose, the external data processing device is connected to the control device via a direct connection, i.e. a point-to-point connection. The AI-based software module preferably processes audio and/or video signals as input signals, which are transmitted from an external input device to the control device and from there to the external data processing device.

Provided is a method for controlling transit of a yarn spindle, an electronic device and a storage medium, relating to the field of computer and automatic control. The method includes: taking each second controller as a target controller, and receiving target business data sent by the target controller when determining that a communication link from the target controller to the first controller is in a normal state; sending the target business data to the manufacturing execution system, where the manufacturing execution system is configured to obtain a target transit indication based on the target business data, and send the target transit indication to the first controller; receiving the target transit indication sent by the manufacturing execution system; and sending the target transit indication to the target controller; where the target controller is configured to carry on the transit control operation for the yarn spindle product transiting the target workstation.
