I am looking to establish communication between an ABB AC500 PLC and an Allen Bradley PanelView 800 HMI using Modbus TCP. As I begin testing, I am curious about the syntax for addressing variables in the PanelView. For instance, can I simply assign the address 40001 to register 40001 in the PanelView? What is the proper syntax for addressing registers and coils in this setup?
I have successfully used Kepware as a gateway with the PV1000 Series in the past, but I am unsure about its compatibility with the PV800 series. While it worked well, there were some challenges when upgrading terminal firmware due to the need for a corresponding version of Kepware. This required extra maintenance to ensure smooth operation.
Thank you for your feedback! I see your point about utilizing Kepware as a gateway, especially when dealing with the PV1000 Series. Right now, I am focusing on testing the PV800 series, which is why I am particularly interested in that specific line of products.
Yes, you can indeed link the address 40001 in your PLC to the corresponding register in your PanelView. When entering the address in the HMI, you should have it in the format '40001', no leading zeroes necessary. However, remember that addressing in Modbus can depend on the Modbus variant and addressing in your PLC. With ABB and Allen Bradley systems, the base address is typically offset by 1, so you might need to use 40000 in the PanelView instead of 40001. Always verify addressing in each device's respective documentation to iron out any inconsistencies.
Actually, when addressing via Modbus, the indexed location generally starts at 0, so the numbering can be a bit confusing. If you're trying to reach register 40001, you might actually need to address it as 40000. Not sure about Allen Bradley's PanelView, but it's always crucial to double-check the HMI and PLC manuals or contact their customer support for specifics. You might also want to assurance the proper configuration of your Modbus TCP communication settings. Good luck!
Yes, you're on the right track with the Modbus addressing. In the PanelView 800, you can indeed assign Modbus address 40001 to a tag that corresponds to register 40001. The syntax is typically like: [::1]:40001 where '::1' represents the localhost. If you’re referring to coils, you could use the addressing schema like [::1]:00001. Please be aware that the syntax might vary due to firmware revisions so it's best to consult the user manuals of both ABB AC500 PLC and Allen Bradley PanelView 800 HMI.
