Hello all, I am currently working with a Modbus RTU slave device (for vibration monitoring) over an RS485 Serial Interface. I am using the modbus-contrib package and flex-getter and flex-writer nodes to handle the requests to multiple slaves on the same serial bus. I think I am currently struggling with timing my requests with the flex-getter. I’m unsure about how long I need to wait before the first request to the first slave, how to set the timeout thereafter and how long to set the queue delay between each message sent while they stack up in the queue. It seems the serial port gets stuck after reading a few times. The Modbus response gets stuck on “initialized”. If anyone has any suggestions or wants to see my setup/code I’d love to find a pair programming partner for more IOT learning and applications.
