We are trying to test extended modbus through RedLion's Crimson 3.2. We have almost finished the project through crimson 3.2 and want to test the tags. Im new to node-red and was hoping for some help with this, i thought this seemed like the right place.
Good afternoon! Thank you for your excellent library, which I am actively using in my IoT projects. When integrating with the WinCC Unified v21 SCADA system, I encountered the following issue. If the polling interval for registers exceeds 1 second (i.e., an interval longer than 1000 ms), brief connection drops begin to occur. However, with an interval of 500 ms or less, the connection remains stable and works flawlessly. The issue might be related to WinCC Unified, but I would like to check if you have encountered similar behavior before.
