Boddeke, perfect for modbus rtu serial testingi am using this for testing and analyzing modbus rtu with a cheapo usb-serial-rs485 connecter and works great. I had some problems with crashes and the data log window and they were fixed in one day after contacting the developer.one feature/use which might not be obvious at first is that this is also very nice to 'listen in' on the rs485 bus. You can 'mute' the app but it will still report what is going on. Very helpful for debugging nasty modbus issues Developer Response,Thanks for the feedback.Great tip on 'listening' to Modbus RTU traffic fro debugging.Just a little side note: listening works only with RS485 ports (multi drop), it does not work with a RS232 ports (you can only listen to one side).
Ctmorrison, Does not work well.at least in 10.11.3After downloading and trying Modbus Server (free) and learning it does not work in 10.11.3, I read the info on the Pro version and it indicates it works “10.6 or later.” So, I spent the $3.99 and have wasted a ton of time (and $3.99) trying to figure out how to create 8 input registers. There appears to be no way to (easily?) create and load 8 input registers. I can’t even create and load 8 holding registers. The server does start up and responds to inquiries. However, it’s basically worthless to me unless someone can tell me how to create the additional registers I need to simulate the device for which I’m writing an interface.The help tool is nicely done, but is of little value, at least with regard to my needs.I would even be happy to hack the.mbs file that holds the register settings if that information was provided.Come on Contech—a little help, please!!!
Developer Response,I apologise for the bug which blocked CMD-A (add register) from working.This problem has been resolved in V3.8.
