Hi, I am a PLC programming expert. I can help you on this project. I've done a lot of projects like this before. For this, I'll just be needing some files and info from you to do this. Like the back-up program, model of the old and new vfd and model of its communication modules. Or we can talk about the details over chat. You can visit my profile to check some of my finish projects on Siemens PLC. Thank you

Hello! I am an electrical engineer, MCU and PLC&SCADA programmer. I have 10 years experience in projects based on PLC&SCADA . I am currently working in this area and has done a lot of projects, and I am sure that your project will be completed in the shortest possible time and according to your requirements and algorithms.

Hello, my name is Alexander, I have extensive experience with plc siemens s7, to carry out your project I would need the original project with the old and new files (gsd), and a detailed description of the process, with the electrical diagrams associated with the vfd , and manuals. Once refined the details regarding the project would begin 10 days for delivery, greetings.

I have 30 Years of Control Systems and Automation. Simply what version of Siemens S7 do you have? I have access to Latest Siemens TIA portal V14. I understand your problem. You have a PLC with Profibus DP comm that includes 1 or more Gefran VSDs. Your latest Gefran VSD is newer and needs a different GSD file installed in the PLC. I have done Profibus DP in both Siemens S7 and S5 in the past. My most recent Siemens work used ProfiNet. Price and Milestones are negotiable. Most important we have to agree on the Scope of work and what you supply to me.

Hi I’m a highly skilled Siemens developer. I have done many big projects with Siemens. Mostly projects for VW/AUDI and BMW and other big processing plants. So there is no problem to solve your issue with the GSD files conversion. I will make a sample project / or implement the new gsd file in your current solution. Correct / change the functionblock for the new drives, Where the actual control/status happens. If it’s possible that I can get online access to your plant, I will make a fully test of the software with you to make sure everything is working. Let’s talk more about the solution and issues to make sure we are on the same track

I work at a control system engineering firm and specializes with siemens plc. We work on different brands of VFD and equipment.

Dear Sir, I have experience with Siemens PLC programming and associated software. Please let me have this opportunity.

Hello, I can do the job. Regards.

I would like to work on this project. I have executed similar type of job in past. I interfaced Yaskawa, ABB VFD with Siemens S7-400 PLC.
