With the transition from traditional fuel vehicles to hybrid and eventually pure electric vehicles, addressing global climate change and achieving carbon neutrality goals, the future of autonomous vehicles cannot be ignored. Today, autonomous driving capabilities are continuously evolving at the vehicle level. The automation levels defined by SAE are shown below: The majority of current … Read more
EKI00006: Configuration failure explained Error Effects: Emergency stop of the track Inputs for activated commands (robot movement, program start) are disabled. Cause: Framework error in the XML file containing the connection configuration. The XML file containing the connection configuration may be unreadable due to framework errors. Ethernet KRL uses the XPath framework. The syntax specified … Read more
How to Connect PLC Using WINCC and TCP/IP Prerequisites The prerequisite for establishing communication between the PLC system and WINCC6.0 via Ethernet is that the PLC system is equipped with an Ethernet module or uses a PLC with a PN interface. The list of Ethernet modules is shown in the table below: Note: Only modules … Read more
Introduction PLC (Programmable Logic Controller) was initially just a digital logic controller with a microprocessor for automation control. With the development of programmable logic programs, PLCs have become widely used in the industrial control field, evolving into programmable automation devices similar to compact computers, replacing the numerous relays and counters in automated control systems. PLC … Read more
Internet Internet The Internet is the largest network in the world today, known as the “network of networks”. It is a massive network that interconnects all other networks. The components of the Internet: Edge part: Host Core part: A large number of networks and the routers connecting these networks (this router is not the one … Read more
This article is a translation of “Let’s code a TCP/IP stack, 1: Ethernet & ARP”. The translation process is also a learning experience for myself. Writing your own TCP/IP stack may seem like a daunting task. In fact, TCP has accumulated many specifications over its more than thirty years of life. However, the core specifications … Read more
