i need to request many data from a single device, using Modbus TCP read; the device is used as a gateway ti other 6 slave with differente Modbus ID (e.g. 192.168.120.100 ID = 1 to device 01, 192.168.10.100 ID = 2 to device 2 and so on ...).
Now, i've import the library "node-red-contrib-modbus" v5.14.0.
I'm currently used the Modbus Read function with poll rate equal to 2 second. Each Read function is call on a different flow.
My question: is possible interlock the 6 Modbus Read nodes?
Is possible start Modbus Read 1; when done, start Modbus Read 2 and so on for the 6 nodes?
wiring in series will cause the operations to occur serially (which you asked for)
As a new user, I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
