They don't say much about their product
I will have to rate on the high side since they don't say what their product will do and it does about that. A hint, don't forget to offset your number by one. Only one number will be read at a time. This routine will send out the basic modbus commands. There is Onother product that will do more of what one actually wants. To request help, you have to join their online support and sign away your life's history away along with all your friends and acquaintances. I think this might be a front to force tekkies to join social media. The software is lean, clean and after much guessing does function as stated.
