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...
Standalone machine development
National Instruments c-DAQ 9181 and C series modules when paired together could be used to achieve complete measurement system. In such architecture, it is possible to transfer data between measurement system (composed of c-Daq chassis carrying c-series module) and labview app using wifi network, bluetooth or ethernet cable. I was once involved with designing weight machines using...
PID Control System
PID control is the most common control algorithm in industrial control applications. This article is merely written to share some of the techniques that I developed in Labview Programming to achieve literally zero overshoot. In my case, I wanted to control hydraulics supply and return pressure via control valves. Such control valves take 4-20mA signal to control...
Synchronised multi-axis motion control
Filling Machines and Production Line
Advanced production line in most industries involve many different processes. For instance, yogurt filling machines involves feeding pot material from a coil into a press machine mounted with die. Finished part out of the press and die is empty pots ready for the next stage. Next stage might involve wrapping pots with...
Autocad Electrical Project upgrade
Autocad import of dwg drawings
One of my client recently handed me over set of electrical drawings in dwg format and requested control panel upgrade with bigger cabinet and more components. My first task was obviously to be able to open all dwg in Autocad Electrical. Original dwg were drawn in a different drawing tool so I...
