Hi there, I am an automation specialist based in Canada with 15 years of hands-on experience in PLC programming. I have reviewed the project description and found it to be very straightforward. I propose to configure and program an OPC UA–based client/server communication between the two controllers, enabling reliable bidirectional data exchange with no practical limitations. This will include both discrete and analog data, as well as allowing the client to send commands to the server controller to operate the connected devices. Please take a look at my profile to review similar projects I have completed and client feedback on the delivered work. Regards, Yasser

Hi there. I’m an automation and embedded systems developer with 8+ years of experience, and I’ve reviewed your requirement to establish OPC UA communication between Siemens S7-1500 PLCs. I’ve delivered 11+ industrial communication integrations, including 5 OPC UA-based PLC-to-PLC systems, handling digital, analog, alarm, and maintenance data exchange in production environments. I will configure the server/client OPC UA architecture, map digital/analog/alarm tags, and implement secure control of the server PLC program from the client PLC with validated data handling and diagnostics. My previous PLC integrations achieved >99.9% communication reliability with deterministic signal transfer under 250 ms, and I’ve implemented 8+ Siemens TIA Portal projects with structured documentation and QA testing. You will receive tested configuration steps, tag mapping documentation, and deployment guidance for stable long-term operation. Could you confirm firmware versions and whether OPC UA licenses are already enabled on both PLCs? Thank you for your time and consideration. Best, Julian

Hi, I understand the critical need to establish reliable OPC UA communication between your two Siemens S7-1500 PLCs, ensuring seamless transmission of digital, analog, and alarm signals. With extensive experience in Siemens PLC programming and OPC UA integration, I have successfully implemented similar projects that involved controlling server-side programs via client PLCs and transmitting essential maintenance data securely and efficiently. My approach emphasizes accurate signal handling, robust communication protocols, and thorough testing to meet your automation goals and operational integrity. I can deliver a functional prototype within 5 days to demonstrate smooth data exchange and control capabilities. Let's set up the communication framework and establish control and data transmission as per your specifications. Could you specify the software environment and any existing configurations on the PLCs that I should consider for the OPC UA integration? Best regards,

✅Okay, I got what you want exactly. I am a senior PLC & industrial automation engineer with over 10 years of experience, providing Siemens S7-1500 programming, OPC UA communication, and industrial data integration solutions. In my opinion, the most effective approach is to design a clean OPC UA client/server architecture where data models, namespaces, and security policies are defined upfront to avoid latency and maintenance issues later. I also focus on structured data blocks and alarm classes so digital, analog, and maintenance data remain scalable and easy to troubleshoot. This project is very similar to my previous works. I recently integrated two S7-1500 PLCs using OPC UA where one acted as a supervisory controller, exchanging over 120 digital/analog tags, 15 alarm conditions, and runtime diagnostics, while also remotely triggering production modes on the server PLC. I handled certificate management, user roles, and optimized polling rates to keep cycle times stable under 10 ms. ✅ So, I will divide your project like following: ⚡ Review PLC programs, network setup, and OPC UA requirements ⚡ Configure OPC UA server/client, security, and data models ⚡ Map digital, analog, alarm, and maintenance data ⚡ Test control logic, alarms, and long-term stability Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and I want to discuss about the budget and timeline in detail. Best regards. Yaroslav
