Comparison Between PanelView 800 and PanelView Plus 7
When choosing the right Human-Machine Interface (HMI) for industrial automation, understanding the differences between models is crucial. The Allen Bradley PanelView 800 and PanelView Plus 7 are two popular choices, each with its strengths.
Compatible Controllers
The Allen-Bradley SLC 500, CompactLogix 5370 (apart from L37 and L38), CompactLogix 5380 (5069-L306xxx), MicroLogix, and Micro800 family of logic controllers are among the tiny and microcontrollers from Rockwell Automation that are compatible with PanelView 800 terminals.
CompactLogix 5370 and ControlLogix 5570 Controllers, CompactLogix 5380 and ControlLogix 5580 Controllers, CompactLogix 5480 Controllers, Micro800 Controllers, and Third-Party Controllers are connected to both Standard and Performance PanelView Plus 7 terminals.
PanelView Plus 7 Standard versions can only connect to one controller, whereas PanelView 800 terminals can connect to a maximum of four controllers within a system. However, depending on the memory and CPU capacity of each controller, 7 Performance terminals can connect to more than one controller.
Remote Monitoring
PanelView 800 and PanelView Plus 7 provide remote application monitoring and troubleshooting using a Virtual Network Computing (VNC) Server. Furthermore, remote monitoring is possible with the Standard and Performance PanelView Plus 7 terminals thanks to a Web HMI Server, an FTP server, a VNC client, and a Remote Desktop client.
Memory and System Storage
PanelView 800 contains 256 MB of RAM and 256 MB of system storage, which is a large amount of memory. PanelView Plus 7 offers far more memory though; the 512 MB RAM, 512 MB non-volatile storage, and over 80 MB of free memory for user storage are all included in the Standard and Series-A Performance terminals. In contrast, the Performance terminals in Series-B Plus 7 offer 4 GB of RAM, 20 GB of non-volatile storage, and around 2 GB of user storage.
Communications
PanelView 800 terminals include built-in Ethernet and serial connections, which handle both serial and EtherNet/IP communications. RS-232 (DF1), RS-485, and RS-232 (DH-485) are among the serial protocols that are supported. Modbus TCP, Modbus RTU (Master and Slave/Unsolicited), and Modbus ASCII are additional third-party network communication protocols that PanelView 800 supports.
PanelView Plus 7 terminals can only communicate over EtherNet/IP. Support for Device Level Ring (DLR) is standard on Plus 7 Performance terminals, but optional on Standard terminals. But in order to enable third-party Ethernet protocols, Kepware Server is included in both the Plus 7 Performance and Standard terminals.
Screen and Alarm Count
With PanelView 800, you can have up to 1000 alarm trigger conditions and 50 graphical screens. By contrast, the PanelView Plus 7 Standard terminal can only support 500 system alarms and a maximum of 100 graphics screens in a single control system. However, there is no restriction on graphical screens or system alarms with the Plus 7 Performance terminal. Its chosen Processor and memory capacity are the sole constraints.
The Rockwell Automation PanelView 800 and PanelView Plus 7 each offer distinct advantages tailored to different operational needs and environments. The PanelView 800 stands out for its cost-effectiveness, ease of use, and sufficient functionality for small to mid-sized applications. It is particularly suitable for those seeking a straightforward, reliable HMI solution with basic features and a quick setup.
The PanelView Plus 7 provides a more advanced solution, with its high-resolution displays, enhanced connectivity options, and expanded memory capabilities. It is ideal for complex and large-scale operations that require robust data handling, extensive user interactions, and high customization levels. The advanced features and capabilities of the PanelView Plus 7 make it a superior choice for environments where performance, scalability, and detailed visualization are critical.
