Eltima’s Serial Port Monitor Enables A PLC to MODBUS RTU Communication

4.0 rating
October 12, 2019

I had been looking for a method to have my JS application communicate to a PLC via the MODBUS RTU protocol. While I was able to communicate the PLC through MODBUS TCP protocol, I was unable to revise the code to function with the MODBUS RTU and so they have not been able to locate each other.
Multiple attempts to connect my PLC to the MODBUS RTU ended with time-out errors unless I rebooted the unit. Obviously, I was frustrated and desperate for a solution.
I eventually came across the Serial Port Monitor from Eltima after trying dozens of options, including multiple MODBUS emulators, with no luck at all. I found that the Serial Port Monitor from Eltima helped me analyze exactly where the COM port error was coming from and helped me figure out how to establish communication with MODBUS RTU.
This Serial Port Monitor also hosts a plethora of features that made other aspects of my javascript application more efficient. As a student ready to break into the field of software development, I’m glad that I found this professional SPM software that makes my future career easier and more efficient.

Serial Port Monitor Helped Me Build A Custom Dashboard on Windows

I wanted to build a custom dashboard for a 3rd-party Li-Ion Battery Management System. The system was based on Texas Instruments BQ76940 and Atmel 8-bit line of microcontrollers.
While I received a brief explanation of the communication protocol, it wasn’t near enough information for the task at hand. This meant being able to analyze the transmitted protocol while using the Windows-based dashboard provided by the manufacturer was a non-negotiable- and urgent- necessity.
After researching several different softwares that just didn’t seem to be what I was looking for, I found Eltima’s Serial Port Monitor. Upon reading into the software, I found that Eltima’s unique SPM was able to “sniff” out any open serial ports on the Windows platform. This meant that Eltima’s Serial Port Monitor was exactly the tool that I needed to complete the project successfully and easily.
Thanks to this SPM, I have no problem seeing the protocol flow in real time, and can now fully understand the documentation being recorded. If not for Eltima, I would have wasted countless hours trying to deal with trial and error during the programming. I’m very pleased that this all-in-one software will be a tool in my programmer’s belt that I can call upon many times in the future.
Thanks, Eltima Team!

Eltima’s Serial Port Monitor Made Me A Better Developer

I often work with serial ports, and require the help of a reliable serial port monitor to help me properly test and optimize the projects I work on.
I found the Serial Port Monitor by Eltima, and I think this professional-grade software has helped me do all of the above (and more) without needless frustration.
Thanks to Eltima’s Serial Port Monitor, I’ve been able to expedite multiple types of development, including: device drivers and application development.
Eltima’s SPM also performs as spectacularly as a coding, testing and optimization platform.
This SPM is a professional-grade analyzer and sniffer that works great for monitoring and controlling ports. I’ve also been able to perform advanced searches and filtering; as well as data and built-in terminal exports.
It’s UI also pleasantly unobtrusive. Allowing users to connect with COM ports and analyse their activity. I’ve even been able to monitor MULTIPLE serial port activities at once, thanks to the ‘sniffer’ function.
The best part about Eltima’s SPM, is that it’s a completely finished software, meaning that I didn’t need to find additional tools for my needs.
I can’t recommend the Serial Port Monitor by Eltima strongly enough to fellow developers. It has made me much more efficient- allowing me to spend less time hassling with SPM’s with fewer features.
