Greetings! I am currently working with an ESA HMI connected to a Simatic S7-300 (CPU312) PLC. I have successfully uploaded the program from the PLC, which was created using Step7 Manager. Now, I am wondering if I can use the same DB9 port to connect to the HMI for an upload, or if I need a separate cable. I have been informed that I may need Polymath HMI software for this task and would appreciate confirmation from someone knowledgeable about ESA's products. The specific model I am working with is VT50500000, revision 2.3, dated 29/10/2010. While the touchscreen is functional, the display shows lines throughout, making it challenging for operators to use unless they have memorized the button locations. The customer has already purchased a new Automation Direct HMI and wants me to replace the current one with it. However, I lack descriptions or any other information from the PLC project, which is why I am keen on uploading the content from this HMI. Your assistance is greatly appreciated. Thank you.
If the VTxxxxx model includes a DP at the end of its name, it is likely equipped with Profibus DP. If not, it may require a DP add-on card for functionality. Communication is most likely through RS485, though there are mentions of RS232 in the manual for upload/download purposes. For more information, refer to the manual available at the following link: https://icdn.tradew.com/file/201606/1569362/pdf/7375230.pdf The software associated with this product is called VTWin.
In order to determine if the VTxxxxx model supports Profibus DP, check if it has a DP at the end. If not, it may require a DP add-on card. The communication protocol is most likely RS485, although it also has a port for RS232 for upload/download functions.

If there is no DP at the end, you may be wondering about the purpose of "the pot."
His intention was to enter the word "port" into the search bar.
I am currently away from home and using an old PC with a slightly dysfunctional keyboard.
Parky mentioned that he is currently away from home and using an old PC with a questionable keyboard. It's my fault for not being able to understand that sooner. Apologies for the confusion.
Hello! Firstly, it’s great that you've managed to upload the program from the PLC; that's often half the battle. As for uploading from the HMI, in my experience with ESA's products, you'll indeed need the Polymath HMI software to upload programs from their devices. Regarding the DB9 port, if it's the standard port that ESA uses, yes, you should be able to upload the program with that, though you may need a RS232 to USB adapter for the connection. The display issues you're describing sound like they could be due to aging hardware rather than a software problem. As for moving to the new Automation Direct HMI, I would suggest talking to their technical support too, they can guide you on their device capabilities and compatibility with S7-300 PLC. Good luck with your project!
Hello! For the connection, the DB9 port should work if properly configured. As you've guessed, you would need the Polymath software to upload from the ESA HMI, given that it is a specialized tool for ESA HMIs which can convert and upload the project to your new Automation Direct HMI. If you are facing trouble getting Polymath, try contacting ESA support or check their official website for downloads. Also, before you do anything, keep in mind to back up your current HMI project. You want to ensure that you have a failsafe in case something goes awry during the upload process. Best of luck with your project!
Hi there! You're on the right track with the Polymath HMI software, it’s definitely necessary for uploading and migrating data from the existing HMI. About the DB9 port, while it should be theoretically possible to use it for both the PLC and the HMI, in practice, you might encounter some problems in terms of communication speed and stability. I might suggest getting an additional cable to ensure a safer transfer. As for the Automation Direct HMI, it's great that you're replacing the old one, as it should enhance usability immensely for the operators, especially given the troubled display on your current model. Don't worry too much about the lack of descriptions from the PLC project, the software should guide you through the process if everything goes well.
Hey there! It sounds like you're in a bit of a tricky situation with the HMI and the PLC. Generally, you should be able to use the same DB9 port for both the PLC and the HMI if your connections and configurations allow it, but ensure you don't have overlapping communication settings. As for the Polymath software, it might help depending on the specific features it offers for your model. Since you’re dealing with the ESAs VT50500000, double-check their documentation or support forums—they often have someone knowledgeable who can provide insights specific to your version. Good luck with the upgrade!
Hey there! It sounds like you’re navigating a tricky situation with the ESA HMI and the S7-300. Generally, you shouldn't need a separate cable for the DB9 port if you’re just switching data between the PLC and HMI, but it's always good to check the specific connection guidelines for your model. As for the Polymath HMI software, it can definitely help with uploads, so see if you can get access to that. Since you're facing display issues, transitioning to the new HMI might be your best bet if the lines on the screen are causing usability problems. If you can’t find the PLC project descriptions, perhaps reach out to the customer for any documentation they might have or explore online forums for similar user experiences. Good luck with the new setup!
