Hello, I have installed a new touch screen but it is showing the error message "connecting to host." I have already compared and followed the address code at the touch panel, tried the plug and play method, but I am unsure if it requires additional setting or if there is a program inside that needs to be addressed. Any help in resolving this issue would be greatly appreciated. Thank you.
When integrating the TP177B program into STEP7 and specifying the connection by selecting the CPU, the connection details should be automatically set. If manually specifying the connection details, ensure to select slot=2 and rack=0 (assuming the target is an S7-300) to avoid a common error. The HMI program should be downloaded to the TP177B, with connection settings being set automatically. However, when using ethernet, the IP address must be manually set on the panel through the Windows Control Panel on the TP177B.
Thank you for the valuable information provided.
How to troubleshoot hash values appearing on Siemens TP 177B instead of numerical data
Has it functioned properly in the past?
If all data fields display "#", it indicates that the Human-Machine Interface (HMI) is currently offline. In the event that certain values are showing "#", it suggests that the values may be too large for the configured field size. For example, the value 12345 cannot fit if the field is only set to accommodate 4 digits. Remember to initiate a new thread for future discussions.
It sounds like you've covered some good initial troubleshooting steps! A possible cause of your issue could be a network connection problem. Ensure your touch screen is properly connected to your network. If it's a wireless connection, the problem might be as simple as being out of range of your router. If it's a wired connection, try testing the device with a different ethernet cable. Also, don't forget to check the software compatibility with your system. Worst case scenario, it might be a hardware issue, perhaps faulty or incompatible with your system setup. Keep us posted!
Hello! It sounds like this could be a connectivity issue. Make sure that the driver for your screen is updated. Also, you might want to check the cable connections between your touch screen and the computer to verify they're secure. Sometimes, the problem could also lie with the host being referred to - can you try pinging the address to see if your system can actually reach it? If these don't seem to work, it might be worthwhile to contact the manufacturer's customer support for a possible firmware issue. Good luck!
It sounds like the issue might be with the connectivity between your touch screen and your host device. Have you tried testing the screen on a different host device to rule out a problem specific to the one you are using? It could also be a driver problem. Check if you've got the latest compatible drivers installed for your touchscreen. Also, look into whether the error persists in safe mode. This would help narrow down the possibilities whether it's a software conflict or a hardware issue. Hope this helps!
It sounds like you're experiencing connectivity issues, which might not necessarily be related to the touch panel itself. Have you checked your host's network connection? Also, you might want to look for any drivers or updates that need to be installed for your specific touch screen. Sometimes, new hardware requires specific drivers that aren't automatically included with plug and play. It would help if we knew the specific make and model of your new touch screen. Checking the manufacturer's website for any technical information or customer support could also be really useful.
It sounds like you've done a good job troubleshooting so far! One thing you might want to check is if the drivers for the touch screen were installed correctly. Sometimes, the device won't communicate properly with the host if it’s missing drivers or if there’s a mismatch. Additionally, make sure your USB or HDMI connections are secure, and if your system has any specific software settings for external displays, it might be worth looking into those as well. If all else fails, consult the user manual for any specific configuration steps that might be needed. Good luck!
It sounds like you're on the right track, but have you double-checked the compatibility of your touchscreen with your host device? Sometimes, even minor discrepancies in settings can cause connection issues. Additionally, make sure the drivers for the touchscreen are updated, as missing or outdated drivers can lead to communication errors. If it's a specific software that manages the touch functions, ensure that it's properly configured. It might also help to restart both the touchscreen and the host device after making any adjustments. Good luck!
It sounds like you've already done some good troubleshooting! One thing you could check is whether the drivers for the touch screen are installed correctly. Sometimes the device might need specific drivers or software to function properly. Also, ensure that your network settings are configured correctly if it's a network-connected touch screen. If that doesn't help, you might want to look into the manufacturer’s documentation or forums for any specific setup instructions that might apply to your model. Good luck!
