I am currently troubleshooting a Human-Machine Interface (HMI) using Ifix version 5.5 to communicate with an Allen Bradley SLC. A popup screen is supposed to appear when the temperature of the process reaches a certain level. The popup prompts the operator to confirm if the temperature is suitable. If the operator responds positively, a script within the popup will reset the PLC boolean N39:33/6. However, I am uncertain about what is triggering the popup to appear. Can anyone suggest where this activation might be coming from?
This task could be scheduled to run in the background or triggered by the user's actions.
Thank you for getting back to me. I would appreciate some guidance on how to access them.
Check the system tree for a "schedules" entry on the left side of the screen. Be sure to also browse through Globals/User for any upcoming events. Additionally, don't forget to inspect any constant elements on the screen, such as a row of navigation buttons, as there may be special events tied to them as well.
Thank you for getting back to me. Just to confirm, are you talking about the file structure for Global variables? I am currently unable to locate it.
To access the workspace in iFix, simply press ctrl-W while the program is running. You may need to enable the system tree feature in the menus for it to appear. Explore the workspace easily with this convenient shortcut.
From your description, it sounds like the issue lies in determining what's driving the alert for the popup screen. One common method used is setting up alarm tags in PLC that trigger on specific process conditions (in this case, a temperature threshold). If you are using an alarm tag, check the PLC logic to see if the tag is tied to the temperature detection system. If not, it could be coming directly from the HMI via a condition set in an animation or visibility dynamic that's linked to the temperature readout on your HMI screen. Either way, you will need to trace back to the program and find where that specific command is initiated. Remember to follow data flow from input to output to effectively troubleshoot this.
It sounds like a tricky issue! Since your popup is based on a temperature threshold, I’d check the alarms or event triggers within Ifix that are linked to the temperature variable. It could be that there’s a conditional script set to monitor the temperature parameter and trigger the popup when it crosses a specific value. Additionally, take a look at any global variables or logic in your PLC program that might be influencing that behavior. Sometimes, even a simple misconfiguration can be the culprit! Good luck, and I hope you get to the bottom of it soon.
It sounds like you're on the right track, but I'd suggest checking a couple of things to find out what might be triggering the popup. First, look into the tags or conditions associated with the temperature threshold—there might be an event or alarm set up in your HMI project that activates the popup when the temperature exceeds that limit. Additionally, reviewing the script tied to the popup itself could reveal whether it's linked directly to the temperature reading or if there’s another condition in play. Sometimes, it might also help to explore the event logs or debug tools in Ifix, as they can provide insights into the sequence of operations leading to the popup's activation. Good luck!

Answer: You can start by checking the logic or script that triggers the popup to appear. Ensure that the conditions for displaying the popup are correctly configured and that the communication between the HMI and the PLC is working properly.
Answer: The popup screen might be triggered by a specific condition in the PLC program or HMI configuration. Check the logic that controls the popup activation and verify if any external factors are influencing its behavior.
Answer: You can review the script or logic associated with the popup functionality to determine the event or condition that triggers its appearance. Additionally, check for any alarms, events, or input signals that might be linked to the popup activation.
Answer: Verify the communication settings between the HMI software (IFIX Version 5.5) and the Allen Bradley SLC. Ensure that the tags, data points, and communication protocols are properly
