Modbus Description
MODBUS is a small-sized and portable protocol simulator which enables you to test SCADA/HMI with modbus RTU and TCP/IP. It features a bunch of handy settings for users with advanced experience in networking applications.No installation requiredThere is no setup pack involved, which makes MODBUS portable. It means that you can save it to any part of the hard disk and just launch the executable file, as well as save the app to a USB flash disk or similar storage unit, in order to run it on any PC with minimum effort and no previous installers. An important aspect worth taking into account is that the Windows registry and Start menu do not get updated with new entries, and no extra files are created on the disk, thus leaving no traces behind after removal. Clear-cut interface and optionsThe GUI is made from a classical window with a neatly organized structure, where a list with all available addresses for holding registers is shown at startup. You can switch the viewing mode to coil output, digital or analog input, or extending registers, toggle decimal and hexadecimal mode, as well as modify the protocol used. It is possible to enable and disable stations from the bottom part of the screen, edit decimal values and save them with one click, change all values to zeros, as well as to set up the communication serial or TCP/IP protocol. Evaluation and conclusionThere were no type of issues in our tests, since MODBUS did not hang, crash or pop up error messages. It has a good response time and works well, without causing the operating system to hang, crash or pop up error messages. All in all, MODBUS gets the job done and can be used by those looking to verify the SCADA/HMI configuration and learn about Modbus protocols.
