 Hey guys I'm trying to get a older (windows 7) laptop full of A-B software up and running for my company. Like may companies, we have been reorganized and the person who bought the software under another company name no longer "owns" this company computer. Long story short, I'm having an RSLinx fault "RSLinx communication server has stopped working". I do not have the original discs or software key number information.   I can pull up the PLC software, hook up to a PLC using the DF1 comms, auto configure and detect the PLCs/panelviews in linx, so everthing, so the ports and cables seem ok to that point. But when I try to go online, or upload I get this fault. Is this an easy fix?   Will I need to reload linx 2.59 (no longer available), or could I download the free RSLinx Lite and communicate through that? I tried to download newer RSLinx classic through my Rockwell account, but Rockwell asks for information I do not have, like original purchasers name and/or Key numbers. I typed in the original company name, but there is a mismatch with Rockwell, who know what info they may have used?  I'd hate to toss all of this software away (RSLogix500, RSLogix5, Studio 5000, Factory View, Panelbuilder, ect... ) because RSlinx has some problem. My company no longer supports this old laptop, and rockwell is reluctant to help. This is really used as a programmer tool, not really a useable business laptop anymore.  I also dont know the legal or copyright issues, or if Rockwell considers my company a continuation of the original owner?? I'm in engineering, not the legal dept. I certainly dont want to stir the pot if I don't have to. LOL

Hi and thanks for youre time  I am a newbie trying to connect to a 1769-L30ERMS using an Ethernet cable. I am using Studio 5000 and RSLinx Classic lite for programming and communication. However Studio 5000 and RSLinx Classic lite are installed on av virtual machine using VMware.  So my problem is two fold. Connect the VM so that it reads from the real computers ethernet port Find and communicate with the PLC from the VM There are guides on how these problems are addressed seperatly. For example https://www.youtube.com/watch?v=JdArYVceO1I and https://www.youtube.com/watch?v=ERLTvcBBK_w however I have not been able to get them to work together. So I was wondering if you, the sages of PLC programming might have some tips or trix that I could test or perhaps even a guide for how to do? Mvh Eric

Hi! I'm using RSLinx Classic, RSLogix Micro English and RSLogix Emulate 500 to emulate a Micrologix 1100 Series B. I'm able to run, program and simulate different input and output with the emulated PLC. Everything works fine. My problem is that I'm writing a program using the nodePCCC library (https://github.com/plcpeople/nodepccc) and I'm not able to connect to the emulated PLC using the address 127.0.0.1 and the port 44818. I tried  running 'netstat -a' on Power Shell and I found out that the port 44818 is not being used.  Could someone help me identify what I'm doing wrong?

Hi there I have an enquiry. We are looking to expand an exisitng Utility system that uses S7 400s and WinCC flexible on MP277. We were going to put in MP277s and S7400s on the expansion until the Declaration of maturity was issued. Now I am a bit confused of my options.....if i have to use TIA portal (instead of flexible) on the expansion spur with my new comfort panel do i have to purchase the new S71200 or S7 1500 PLC or can i use a S7400 ? If i can use an S7 400 with the TIA comfort software then what do i program the s7400 in? thanks
