Visual Studio 20008 users can now download updated source off SourceForge, the official home for this project's source. But don't run away, the site is still getting updated with infos.

I am being made redundant, so this project is going to probably see a little activity for a while (I hope it's only a while). Check the ticker to the left.

I am moving my hosting, so if you are seeing this, you are seeing my new location. The content is much easier to update now because I am now using Google sites, but it is also a little less rich., which was not much to start with anyway. It might not sound like much, but I moved to a free host to save money - I really stopped updating the simulator about 3 years ago, so the fact this site is still around is pretty much due to the interest level still today. I am not a business, this site and application is all my own work.
Quick-start
This free protocol simulator was
originally designed to allow testing of modbus master devices over
serial, hence the name: Why is it called MOD_RSSIM?
Because it started out as a modbus RS232 simulator - but it grew as all
applications do, and even after adding TCP/IP support the name still stuck. MOD_RSSIM also allows itself to be used
as a "virtual" PLC for comms testing, training and limited use as a
source-code resource. Please download it
to try it out, if it works for you, about 45 minutes later you will get
a nag-screen, either mail me, or use my free registration-key request
screen at the bottom of the page. The sim carries on working after the nag-screen, it just gets tedious clicking on the "OK" button.
An intuitive if not simple user-interface was my goal with the simulator, next I will try guide you through how to get started.
 - Please follow the website menus to more information, like the FAQ and Help.
- Download the simulator.
- Run it, and select TCP/IP or serial protocol.
- If you want serial, you can try using com0com (see the links page) to create a local loopback, and skip the serial cable.
- Select
your serial port from the settings dialog (or if TCP/IP, simply point
your HMI/SCADA to the local IP address) and connect.
- Next you can click on the "Comms" button in the bottom-right to see the state of the communication link to see if your master is trying to connect and talk to the simulator already.
- Now go and look at your scada/hmi, if it's not already talking, go into your drivers and make sure they are started (in most cases no license will be needed from modbus protocol in your scada simply because it is so popular for verification), and if still not talking, look at your own communication logs.
- Unless you are doing something wrong, you should have zeroed values in the SCADA. Now for some fun..
- ...more steps to follow.
- The built-in help engine starts when you hit the
universal "F1" key. You will need to have a default web-browser
installed (no internet needed) to view the help.
- Setting up
the simulation for use will cover it's configuration for different
applications in detail. The first point we come to however is which media type the simulation should use.
- Screenshot showing Allen-Bradley MASTER
protocol emulating a continuous coal miner. Selecting a different
protocol opens up new options for setting up each protocol as relevant.

Contact/Registration
Registration Key here: the key merely gets rid of the nag screen, click on the link to get it. It does not enable new features.
- Download the file
- Run it (Ignore the warning about this being unsafe)
- Run the program
- Enjoy
Support : If you have questions, comments or bugs to report, please follow this link to the Source-forge tracker, (you will need a sourceforge, hotmail google or an Open-ID account to log a request).
- Alternately mail me using this address in the graphic
Beer money
 This simulator is free, if you do like it and want to encourage it's development, please donate via Sourceforge (PayPal etc.) by clicking on the button to the left. It costs me about £15 a year for the domain, so random donations are appreciated.
