I need guidance on using Unitronics V570 HMI with a 3XB snap-in I/O for implementing a PID control in a ladder diagram to regulate a tank's heating element.
Great man to work with, very knowledgeable, very helpful, will definitely be utilising Ognyan’s expertise again.

Project for Ognyan O.
Within this project we searched for experienced professional software developers or system administrators to fill out a survey. Working with this freelancer was exactly what we were looking for! Working with them helped us a lot with our research project. The communication in advance as well as the survey participation were extremely satisfactory and highly professional. Thank you very much for the opportunity to learn from your experiences.

Project for Ognyan O. -- 18/09/25 22:34:26
Absolutely fantastic Job. Not only completed the programming of PLC controller to our requirements with some complicated requirements . Went above and beyond what i asked and provided a much more practical solution than i had asked for. The program is in use in a commercial product and achieving consistent sales and the program is faultless. I have no hesitation in recommending Ognyan O for your project. At times we received a response to questions at a weekend, never more than a few hours to wait
