Hello, I am in the process of uploading a program from an existing PLC S7-1200. I created a new project in TIA v15.1 and successfully uploaded the project. However, when I went online, I received notifications about differences between online and offline modes, as well as discrepancies in lower-level components. I would appreciate any assistance in resolving these issues. Thank you.
This issue often arises when there is a discrepancy between the firmware version set in TIA and the firmware in the PLC. As long as the PLC's firmware version is equal to or higher than the version set in TIA (2, 3, or 4), it should not cause any issues. It is important to note that PLC firmware is updated more frequently than TIA software.
BryanG suggested that a common reason for mismatched firmware in Siemens PLCs could be that the version set in TIA doesn't exactly match the version in the PLC. To avoid issues, ensure that the PLC firmware version (2, 3, or 4) is higher than the TIA version. PLC firmware updates are more frequent than TIA software updates. Can you provide guidance on setting the firmware in TIA to align with the PLC firmware version? Thank you for your response.
In order to transfer a live PLC project to a PC using TIA Portal, follow these steps: 1. Begin by creating a new project, 2. Then, navigate to the PROJECT VIEW and select Online -> Upload device as a new station (both hardware and software), 3. Choose the PLC to upload, 4. Finally, go online to complete the transfer. This process allows you to seamlessly upload your PLC project for further analysis and testing on your computer.
In order to transfer a functioning PLC project to a PC using TIA Portal, follow these steps: 1. Begin by creating a new project, 2. Then, in the project view, select Online -> Upload device as a new station (hardware and software), 3. Choose the PLC and initiate the upload process, 4. Finally, go online. I followed these instructions and successfully uploaded the project, but I encountered issues when trying to go online.
To start a project, begin by creating a new project and adding hardware. Choose the s7-1200 model, then expand the tree and select 'unspecified s1200 CPU.' At this point, a yellow dialogue box should appear with 'detect' highlighted. Click on detect to upload the specific CPU hardware. Once online, upload to bring up the blocks and the rest of the hardware.
It sounds like you've run into a common issue when transitioning projects between the PLC and TIA Portal. These differences often arise when there have been modifications made directly on the PLC that haven't been reflected in your offline project. To resolve this, you might want to try comparing the online and offline versions using the “Compare” function in TIA Portal, which can give you a clearer picture of what's different. Additionally, if you have access to the original documentation or source of the program, verifying the specific changes made on the PLC can help you sync everything up appropriately. Good luck!

Answer: 1. Why am I receiving notifications about differences between online and offline modes when uploading a program from a PLC S7-1200 in TIA v15.1? - The notifications about differences between online and offline modes typically occur when there are discrepancies between the project settings and the actual PLC configuration. This could be due to changes made directly on the PLC or differences in the versions of the project and PLC software.
Answer: - To resolve discrepancies in lower-level components, you can compare the online and offline configurations to identify the specific differences. You may need to manually adjust the settings in the project to match the actual configuration of the PLC.
Answer: - Common reasons for upload issues with a PLC S7-1200 in TIA v15.1 include differences in project and PLC settings, version compatibility issues, changes made directly on the PLC, or communication errors between the software and the PLC. Troubleshooting these aspects can help identify and resolve the upload issues.
