Edge. Modbus Serial Node. No Parity and Stop Bits?

Kevin,

First of all, I’ve got it! For some reason I was thinking that Timeout is in seconds, but seems to be in milliseconds. So, I was able to read my first register :slight_smile:

Regarding the settings, there is function code and offset for the address. According to my experience (that might be very limited comparing to other control engineers/forum members), the combination of those settings differs from one to another modbus implementation. I would say it would be nice to have “default” Losant settings and also a leverage to change it.
There are some modbus tools that allow to give a wide range of settings and preview bytes you send to the device.
The most convenient tool for Modbus RTU testing I’ve used called Simply Modbus. I will provide a screen shot for your reference, otherwise there is a demo version available on the manufacturer’s website
