We have supported the Modbus protocol for quite a few years, and the use of this protocol in our dataloggers seems to be increasing. Therefore, as many of you who use the Modbus protocol already know, we need to compile an application note that will answer most of the common and some not so common questions customers have when implementing Modbus.
I would like to know of the questions you would like answered that are not discussed in the datalogger manuals. I look forward to your suggestions.
Regards,
