Hello, I am new to PLC programming and connections. I have a project where I need to integrate signals from 5 PLCs into a single visualization screen. The PLCs are functional, but I want to streamline the interface. Should I utilize an OPC server from Automation Builder v 2.5 or 2.6 for the PM554-eth PLC? The previous installation was set up with RS485 communication, with one PLC serving as the master and the others as slaves. Should I stick with this setup or switch to TCP/IP for connectivity through a router with the same gateway? I am unsure of the best approach and would appreciate any tips or guidance.
One option is to activate ModbusTCP on the PLCs and utilize AdvancedHMI as a suitable interface. I created a comprehensive tutorial in the past on setting up the PLC, which remains relevant today. Additionally, there are various free/open source HMIs available for use. It is recommended to avoid using OPC due to its limitations and associated issues with DA.
Welcome to the world of PLC programming! Both Automation Builder v2.5 and v2.6 should be compatible with your PM554-eth PLC but it might depend on the existing systems you have in place and their compatibility as well. As for your communication setup, an OPC server would likely help streamline your data from multiple PLCs into one visualization screen. Sticking with RS485 or switching to TCP/IP really hinges on your specific needs. RS485 may suffice if you want to maintain your existing setup and your PLCs aren't too distant from each other. On the other hand, TCP/IP would allow greater reach and could come in handy if you plan on future expansions. I'd recommend having a solid understanding of your current and future needs before deciding the path to take.
Hi there! Both options, OPC server and TCP/IP, have their own pros and cons. However, considering multiple PLCs involved, I'd recommend shifting to TCP/IP. It's more modern and robust, offering better diagnostics and communication capabilities than an RS485 setup. The OPC server will provide a uniform platform for interacting with your PLCs, which is beneficial when different PLC models are used. On a side note, Automation Builder 2.6 is generally more reliable and has better features, so opt for that if possible. Remember, network communication planning is fundamental in such projects so ensure you have a solid plan fragmented into achievable targets. Good luck with your project!
