Hi. I would assume there is an existing PLC (CPU315) and PLC project for which you are needing to create an HMI design (TP1200) for. It is from this project that you can create a 'proxy' from. The 'proxy' can be created from a Step7 V5.5 project or from a Step7 under TIA project. This link may interest you: [LINK]. A 'proxy' is a stand-in for the PLC. It contains only the data structures that is required to make your HMI project work. The 'proxy' does not contain the program... the HMI does not need it. The nice thing is that you can more quickly create links to the data that needs to be handled by the HMI. The PLC design and HMI design can flow more-or-less independently after the linking data structures between them are in place. I should mention also - it is not only the data structures but the communication linking that is also configured. The HMI and PLC projects does not have to be integrated into one project. Does this help you? |
