Hello everyone, I'm excited to start my first discussion here! It has been three years since I last programmed an AB Controller, and I’m ready to dive back in. A new client has requested a system that integrates four CompactLogix controllers. Three of these will act as sub-stations to handle control and I/O, while the fourth will function as the main "Head" controller to relay information between the sub-stations. All PLCs being used are the 1769-L30ER models, each equipped with their own HMI. My plan is to connect all the controllers and HMIs using the onboard Ethernet/IP interfaces to facilitate data exchange among the PLCs. Recently, the client expressed a need to integrate a SCADA system with the "Head" PLC for sending and receiving data over Ethernet TCP/IP. To achieve this, I believe I will need a separate communication processor, but I’m having trouble locating one in the product selection toolbox. What are my options? Should I consider upgrading the "Head" PLC to a ControlLogix model, or is it feasible to implement this configuration with the CompactLogix series? Thank you in advance for your guidance and assistance!
If you find yourself in need of communication cards compatible with various PLC platforms, you may need to explore third-party options. Several manufacturers specialize in producing these communication cards. For instance, you can check out ProSoft Technology's offerings for Rockwell Automation products: [ProSoft Technology Communication Cards](http://www.prosoft-technology.com/Products/Rockwell-Automation-In-chassis). This is just one example; there may be additional solutions that could meet your specific requirements. However, it's important to note that third-party modules can introduce added complexity to your system. On the other hand, using ControlLogix solutions can simplify integration, albeit at a higher cost. Please note: the link provided earlier pointed to a specific model, but this new link directs you to a broader selection of devices available for Allen-Bradley systems.
Markham stated: Hello everyone, To clarify, do I need a dedicated communication processor for this task? I'm unable to locate one in the product selection toolbox. What are my options? Welcome to the Forum! The necessity of a separate communication processor heavily depends on the current load of the "Head" L30ER CPU as well as the complexity of the SCADA application's connectivity requirements. Theoretically, if the SCADA PC is connected to the existing L30ER’s Ethernet subnet, it should be able to exchange data with the "Head" CPU without disrupting the current application. If the "Head" L30ER is operating at less than 50% capacity, implementing a basic SCADA interface could be feasible. However, I emphasize 'theoretically' because, in practice, control systems are designed to segregate different types of data transfers. Typically, I/O data and Logix Produce/Consume data are exchanged over separate subnets from SCADA information due to their differing timing requirements. If you're looking to allow for future enhancements, I recommend upgrading the "Head" CPU to one of the latest 5380 CompactLogix controllers. These models come equipped with dual Ethernet ports, allowing for the SCADA system to connect through a separate port from the one currently linked to your existing setup. You can find more information [here](https://ab.rockwellautomation.com/Programmable-Controllers/CompactLogix-5380-Controllers). Additionally, you may need a SCADA protocol Logix Gateway, as mentioned in the previous post's link, particularly if the supervisory system does not support Logix languages.
Thank you for your assistance! I will be quoting the 5069-L310ER with Dual IP mode for the PLC, along with a Protocol Converter from Prosoft. I have one final question regarding the HMI: I initially calculated the PanelView Plus 7 with a 10" display for my system, as I have successfully used this model in the past three years. However, I'm now reconsidering my choice in light of the newer PanelView 5000 HMIs. Do these updated models offer enhanced features, such as improved graphics and functionality? My top preference is the PanelView 5500, model 2715-T10CD. Thank you once again for your support! This is a fantastic forum.
The PanelView 5000 series, which includes the 5500 and 5310 models, has been a game-changer in the world of operator graphic terminals, moving away from the traditional PanelView, PanelView +, PanelView + 6, and PanelView 7 HMI systems. These advanced terminals are fully integrated with the Logix controller platform, utilizing the same powerful configuration software suite, Studio 5000. They seamlessly connect to the Logix controller's 'I/O Tree,' enhancing operational efficiency. This innovative HMI functionality enables 'real-time' connectivity through I/O classes, increased responsiveness, and potentially reduces congestion on the controller's network. Unlike older HMI models, the PV5000 (5310) does not utilize 'broadcast' data transmission, which contributes to improved performance. While I have yet to implement a PV5000 application—favoring more established hardware to avoid the initial bugs—I appreciate the Logix 'I/O Tree' connectivity, the advertised functionalities, and the streamlined single software platform for configuration. As for reliability, user-friendliness, available support, and any historical issues, only time will reveal their true performance. For further insights, there's an ongoing discussion among users of the PV5000 HMIs that delves into their features and capabilities. Check out the conversation here: [PLC Talk Forum](http://www.plctalk.net/qanda/showthread.php?t=115369). In summary, the PanelView 5000 series marks a significant advancement in HMI technology, offering enhanced integration and functionality for modern industrial applications.
Hey there! It sounds like an exciting project you've got ahead of you! For your setup with the CompactLogix 1769-L30ER models, you can indeed integrate a SCADA system without upgrading to ControlLogix. The L30ER supports Ethernet/IP natively, but for more advanced communication like SCADA, consider using the 1794-AENTR or similar communication modules that best fit your needs. If you're looking for a dedicated communication processor, the "Communication Modules" section in Rockwell's product guide should help you find suitable options. Just make sure any module you choose can handle your SCADA's protocol requirements! Good luck, and it sounds like you're on the right track!
Hey there! It sounds like an exciting project ahead! For your SCADA integration, you don't necessarily need to upgrade to a ControlLogix model; the CompactLogix series can indeed handle Ethernet/IP communication effectively. You might want to consider using the 1769-ENBT (Ethernet Bridge) or the 1769-ER (Ethernet/IP communications module) for your CompactLogix system to facilitate seamless communication with your SCADA. These options should allow you to connect multiple devices without having to shift to a more complex setup. Just make sure to check the compatibility of your SCADA system with CompactLogix; most modern systems can communicate over standard Ethernet protocols. Good luck, and can't wait to hear how it goes!
