Control Melsec-FX-5U over internet in realtime
cyberdrag posted a topic in MitsubishiHi All, I'm new to using PLC, and my background is majorly programming. I am learning how to control a PLC over the internet using HTTP or TCP/IP. I have a Mitsubishi PLC Melsec FX-5U 32MR and my requirement is, I want to send create a setup where the PLC works more like a Client on the network and reads values from the server (which is a computer). The outputs on the PLC are controlled by the values on the database in server. So, lets assume I have a value like this on the server "1,0,0,1,0,1", it should translate like below: Y0 = 1 Y1 = 0 Y2 = 0 Y3 = 1 Y4 = 0 Y5 = 1 Is there any guidance where I can read through and learn how to do this. I would prefer doing it by ST programming and not Ladder.

Which website name is better in your opinion
OrionK posted a topic in General Topics - The LoungeHello everyone! Need your advice. I own a company and want to start building a web site for it. I have two domain names registered and cannot decide which one is better looking. I will mask the name some so that it does not look like advertising here. So the company name is ***Tech Systems. Offering services in controls engineering and electrical engineering. Yes, I am a self-employed contractor doing programming, control panel design etc. for customers. I will also sell some software products (also controls engineering focused) So I have two website addresses that were available and I registered both: 1. ***techsys.com 2. ***tech.systems Please post your opinion about non-dot-com address vs. shortened/incomplete name in address. Thank you everyone in advance. Every opinion matters a lot to me.
