Advancement in machine safety devices
Operation of safety relay
The typical design of a safety relay is based on the classic 3 contactor combination. The design ensures that wiring errors do not lead to the loss of the safety function. Two relays (K1, K2) with positive-guided contacts - set of NO and NC contacts that operate together so NO and NC...
TCP/IP and UDP communication
Benefits of TCP/IP and UDP
Connectivity between devices is become very common and often beneficial essentially in industrial devices communication. Although Modbus, RS485 serial communications have its place still in industrial control and measurement applications, TCP/IP and UDP offers so much diversity that even apps written for I-phone and android could be used to connect with complete...
Programming FPGA and CRIO
In this article, I wanted to briefly go through few practices that I use to develop a compact rio application. A full Compact RIO controller combines FPGA with real time processor. Labview developer could utilise all target levels to develop machine app that would offer maximum resources utilization and reliability to mention only few of the...
