Publication number: 20230356345Abstract: A multi-type industrial robot control system may include: an automation controller; and a programmable logic controller (PLC)-robot bridge. The controller stores a general-purpose robot control function block generated using a unified design standard, calls a corresponding robot control function block for a robot and using robot state data and puts out corresponding first command data to the PLC-robot bridge. The PLC-robot bridge virtualizes robot interfaces of corresponding offline programming functions of different types of robot as a unified virtual interface, calls a corresponding offline programming function via the unified virtual interface according to the first command data, and generates second command data for output to a corresponding robot controller. The corresponding robot controller controls a corresponding robot. At the same time, robot state data from a corresponding type of robot is received via the unified virtual interface and the robot state data is fed back to the automation controller.Type: ApplicationFiled: September 30, 2020Publication date: November 9, 2023Applicant: Siemens AktiengesellschaftInventors: Zhi Min Chen, Zi Jian Wang, Xu Zhao, Wen Feng Liu, Shun Jie Fan

Patent number: 8454382Abstract: An electrical connector includes an insulative housing (2) defining a port (102, 103) and a contact module (5) inserted into the port. The contact module includes a set of contacts (540, 542) received in the port, a ground component (5323) for grounding and a horizontal PCB (541, 543). The horizontal PCB having a first conductive trace (5410, 5430) disposed at the upper side of the horizontal PCB, a second conductive trace (5411, 5431) disposed at the lower side of the horizontal PCB and a shielding layer positioned between the first and second conductive traces. The first and second conductive traces electrically connect with the set of contacts, respectively. The horizontal PCB has a ground section (5414, 5434) electrically connecting with shielding layer to the ground component for grounding. The shield layer is provided to shield the crosstalk between the contacts that are provided as differential signal pairs.Type: GrantFiled: January 13, 2012Date of Patent: June 4, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Zhi-Cheng Zhang, Zhi-Jian Liu, Li-Chun Wu
