Vision V350 has a good trend display library but I could not find a ready to use library to plot XY graphs where X does not means the time axis. Sometimes you might need to relate two values like temperature X pressure in a graph form in order to make a better process analysis for instance and proposed solution shows a method to create a cursor and move that cursor in a plot area in accord two distinct values like shown below: These two links below are about how to control the fan cooler PWM signal using a PLC (theory and practice) and the second one approaches the graphic design method. Part 1 - theory Part 2 - practise (Ladder and downloadable files) In time: All videos included in the post have English captions so you just need to enable them. Folks, I am not English native speaker so if you have tips and hints and fixes, please do not hesitate tell me what to improve. Thank you and hope it helps.
Hi. Take a look at this website -> http://nets-nuts.com.br/pt/industria/vision-v350-indusoft-modbus/ That site has a table relating Indusoft I/O addresses to Vision V350 registers enabling you to easily connect each other. I have done that table checking the Indusoft driver documentation and the the Visilogic Function Blocks V230-21-G23 Rev: 3:00 manual. Last three links in the page have following sample projects for download (as is): -> V350 Modbus slave using serial port -> V350 ModbusIP slave using Ethernet interface -> Indusoft project using MOTCP drivers (Modbus IP) Hope it helps and please, let me know if that worked for you and if I need to improve something.
In 02/Dec I've finished a graduate course at SENAI and my term paper was about how build a simple Java application and get a Vison 350 PLC communicating with a Linux server without using OPC and a step by step jig construction. In fact I did two Java applications 1- TCP_Server which a Linux server timely receives data sent from V350 PLC 2- TCP_Client which implements the Unitronics ASCII communication protocol allowing an user read and write any PLC registers of Vision V350 model May be that code could work for other Vision models. That Java code is available for download "as is" and hope it helps everybody to get their PLCs communicating. Find below my website link English version http://nets-nuts.com...cs-with-linux/ http://nets-nuts.com...lc-testing-jig/ Brazilian Portuguese version http://nets-nuts.com...nics-com-linux/ http://nets-nuts.com...-giga-de-teste/ Java code can be downloaded at SourceForge website : http://sourceforge.net/projects/plc-unitronics/
