is a program that allows you to run through the communication process between a master and slave instance, granting you the possibility of checking if there are any irregularities.
As a tool meant to facilitate the exchange of information via serial lines, this software allows you to test and modify the proceedings of that exchange in multiple ways. There are three modes to handle the communication: the TCP, UDP, and RTU protocols, which have to coincide between the master and slave.
Moreover, considering that the master is tasked with reading the information supplied by the slave, it has several features to do so efficiently: it can read and write single or multiple coils to handle discrete values, and the same functions are present for registers, which are to supply the numerical values.
There are different ways to go about seeing those read and write operations. They can be displayed as LEDs for an easier reading, or as binary, hex, integer, or FloatReverse values. These settings can be changed separately in the master and slave instances, so you can have the former read out binary numbers, while the latter shows them as integers.
When it comes to saving or introducing data, you have the option of exporting or importing your work. This is done in the .csv format, meaning that you can check the saved values in Excel.
