Is it possible to create a visibility expression using the IP address of the HMI (Dynics, not PV) to display specific elements? The client wishes to utilize a single file for two HMIs located on opposite ends of a production line. However, there is an issue with the layout orientation on one side.
While I may not be well-versed in IP addresses, I have experience developing applications for multiple stations with similar functionalities. These applications usually start with the operator selecting their station on the startup screen, which then loads the appropriate screens for that specific station. Perhaps a similar approach could be used for your project - for example, the first screen could prompt the operator to choose between the left or right side station. This way, the system can easily cater to different station configurations.
In my opinion, Ken's suggestion is the right approach. What could happen if a technician unexpectedly alters the IP address on the station? Consider making it memory retentive and concealing the option to modify it in a 'settings' section for added security.
Ken Moore discussed how he has experience with applications that involve multiple stations, all of which were nearly identical. The operator would select their station on the startup screen, and then the corresponding screens for that station's application would load. It's a simple yet effective way to manage multiple stations. This method involves the first screen prompting the operator to choose between the left or right side station. This approach streamlines the process and ensures efficiency. Thank you for the suggestion!
Using the IP address to control visibility in your HMI setup is definitely a creative solution! If you can identify the HMI's IP address as part of your visibility rules, you could program specific elements to show or hide based on that. However, make sure to handle the layout differences appropriately—consider using a combination of conditional logic and possibly scaling or adjusting elements based on the IP detected. This way, you can maintain a single file while still accommodating the unique requirements of each location!
