Ihad Rslogix 5000 program downloaded to Rsemulate and had Rslinx OPC topic setup. The rslinx version is Gateway, and the OPC server can be seen from RSLINX OPC test client, which means the rslinx opc server has been successfully setup, I assume.
Now when I come to ignition to setup the OPC-DA for rslinx (I saw one of the post recently saying that rslinx should be setup on OPC-DA instead of OPC-UA), the status for this OPC server is always faulted.
Classic OPC is based on COM, which is a technology in Microsoft Windows. Therefore, the information in this section only applies to Ignition Gateways installed on Windows. For other operating systems, OPC UA must be used.
I believe FactoryTalk Linx supports the (more) modern OPC UA protocol. If FT Linx is an option, I would recommend pursuing it.

Even better is to configure RSLinx Classic and FT Linx together to permit IA's native driver (and any other products) to make ordinary EtherNet/IP connections to Emulate5000. Then you just have to repoint your driver when moving from development to deployment.
I am working with Allen Bradley's Connected Component Workbench to program a Micro 830 Controller. I'm having an issue when I try to connect to the controller via USB. The USB never comes up in RSLinx even though Windows Device Manager says the driver is installed and working correctly. I am running Connected Components Workbench version 10.01.00 on a Windows 10 machine plugged directly into the Controller via USB and I know that I can connect to the PLC with another machine in the office. Is there still something I'm missing?
For some reason I have 2 Flexy in the field and I can no longer connect to them. The service is working and I confirmed through eneblingelements that it is passing data. eCatcher is connecting and talking with eWon. I confirmed through the customer the eWon has at least 2 signal lights on. I have reconfigured drivers multiple times in RSLinx and I have made sure to map the IP correctly. I can ping the eWon in CMD window as well.
After a few moments, you should see your CompactLogix processor appear under the USB driver in the RSWho window. At this point you can use this USB connection to your CompactLogix to flash firmware, change the Ethernet address, download a program, and go online:
I have been looking for a solution as well. I have studio 5000 v30, as well as v30 emulate. I have the factory talk linx, rs linx lite, as well, and I have yet to be able to get it to work. If you find any answers, please post here.
The current OPC DA client driver available on v2.4.3 is unable to connect to RSLinx Classic due to some bugs present on the third-party library we are using. During the past few weeks, we have been working on a new OPC DA driver since many users still use RSLinx Classic. We are expecting to release a preview version of v2.4.4 early next week, which will include a redesigned OPC DA driver together with several performance improvements related to OPC UA and several bug fixes. You will be able to find the download of preview v2.4.4 on the Announcements category.
Hello Sir,
I have everything all set up on my laptop. (Studio 5000, Rs Linx OEM, EMULATE) I have also updated to the current FIO 2.4. I absolutely love the FIO package and I am excited to get this to work with emulate as I have a really nice controller which I have to yet to wait in order to get repaired. (L27 ERM). It is very important to me to begin writing my code for some of my FIO creations. I have had alot of success with Siemens, Do More(Automation Direct). I appreciate any input or feedback.
Thank you,
and Best regards.
Hi, I found a way to connect Studio 5000 Logix Emulate to Factory I/O. The connection is through ethernet using FactoryTalk Linx Browser, Studio 5000 Logix Emulate, and Studio 5000. I have tried it using all the latest versions of AB softwares (v32) mentioned but I think it would work with versions that support FactoryTalk Linx browser as well.
I only have studio 5000 v30, and unfortunately there is no option to select rslinx or factorytalk linx from the communiciations tab. Even with no project file open. I will explore a bit further. Thanks for the feedback.
With most modern PLCs, all you need to start programming or troubleshooting is to plug in your laptop with a plain old ethernet cable. Older PLCs, however, tend to use a myriad of different cables and protocols. With a large number of legacy systems, the original programming cables and software are often long lost by the time you want to make updates or need to troubleshoot an issue.
If you have access to the original PLC program (typically a .RSS file) and a copy of the RSLogix 500 programming software (contact your A-B distributor if you need one), you can open the project and check the communication settings by double-clicking on Channel Configuration under the controller section of the project tree:
DH-485
This protocol requires a special USB converter, the 1747-UIC, which you can order from A-B or find a number of 3rd party versions online. In addition, you will need the female-to-female null modem crossover DB9 serial cable or a straight-through RJ45 ethernet cable, depending on which port you want to connect to. Make sure you also set the selector switch to RS232 or RS 485.
The 1747-UIC adapter only supports 19200 baud out of the box. If you have an original A-B unit, it is possible to change to the baud rate to 9600 by following the steps in this Rockwell knowledgebase document (requires creating a free account and logging in).
DF1
From the drop-down, select RS-232 DF1 devices and click Add New. Select the right COM port and click Auto-Configure. The driver should be able to figure out the correct settings.
Another mechanism of communication between applications and RSLinx is through the DDE server that comes with RSLinx. The DDE server is only available for Rockwell Automation DDE clients in the OEM version. The drawback of DDE connection is that it is slower than OPC. If you decide to use the LabVIEW DDE VIs, then you need to have the full version of RSLinx.
This document was created using RSLinx 2.20.01.107.01, Allen Bradley MicroLogix 1500 PLC, ServerExplorer 2.4.1, Lookout 4.5 and the LabVIEW DSC module 6.0.2.. The cable model number used was 1761-CBL-PM02.
Lookout can connect to the RSLinx OPC server through the OPCClient object. This document assumes that you know Lookout. If you do not have any previous experience with Lookout, then we strongly recommend you to go through the introductory material in the Lookout documentation.
Note: Lookout currently does not have drivers for the Allen Bradley Control Logix PLCs.
LabVIEW itself is not an OPC Client, but it can be used to communicate to OPC Servers through the DataSocket VIs. DataSockets have an OPC layer, allowing you to read and write to an OPC Server from LabVIEW (or LabWindows/CVI).
DataSocket is a technology based on TCP/IP composed of two elements: the DataSocket API and the DataSocket server. The API provides an interface for different data types, converting the data into a stream of bytes that can be sent across a network via TCP/IP. To learn more about DataSocket, visit Integrating the Internet into
Your Measurement System.
The following is a brief example of how to connect to RSLinx OPC Server from LabVIEW using our example VI.
Insert the controller's IP address into the Host field. On this panel, you can also define how many I/O Points to use, as well as the controller's tags they reference.
Press Esc to return to the Driver Window. Now, click on CONNECT to connect to the PLC. A successful connection is indicated by a green icon next to the selected driver, as well as next to the driver's name displayed on the status bar.
Rockwell RSLinx Classic is the most commonly used edition of Rockwell Automation's brand of PLC communication software. The software facilitates communication between all Allen Bradley/Rockwell automation devices. That includes but is not limited to PLCs, PACs, and HMIs. The most common use of RLinx Classic is communication between your computer and the Allen Bradley devices.
The best way to give you a clear understanding of what is RSLinx classic is is to show you a couple of sections from one of the first units in our RSLogix 5000 course. Especially since one of those sections is an RSLinx Simulator. The RSLinx simulator below is a recreation of one of the many simulations included in our RSLogix 5000 course software. As we had to recreate the software simulation to work online, we went ahead and applied some gamification to it, so you will have even more fun.
The RSLinx software creates a bridge between the automation editing software like RSLogix 5000, and the automation device, like a PLC or HMI unit. RSLinx Classic can be accessed through the RSLogix 5000 software menu by clicking on the RSWho icon or opening directly from the windows task manager. The basic function of establishing a connection with a new device requires the user to install the appropriate communication driver type in the RSLinx software. If the needed driver has already been installed in RSLinx, then often some modification of that installed driver is necessary to establish communication with the new device.
Below is a short overview video created from the first section of the course unit. It may be useful to those who are new to Rockwell automation software. Then well end this article with the new RSLinx simulator game teaching how to add a new driver in RSLinx. You may notice in these examples we are using RSLinx Professional Edition, but the edition is not important at this point. As the functions in RSLinx Classic Edition, are the same in all other editions. The difference between software editions is that the other editions like Professional, OEM, etc. have extra and enhanced features in addition to the standard features found in RSLinx Classic.
