Hello, I am interested in setting up an alarm system using 2 tags in our banner. I would like to create a graphic that will appear if both tags are not active (tag1 + tag2 = 0). Is there a method, such as scripting, to trigger an alarm in the top banner based on this graphic? Unfortunately, we do not have access to the PLC for this equipment as it is managed by an external contractor. Otherwise, I would have implemented the alarm directly in the PLC code by creating a new tag. Thank you.

Utilize a BL (Boolean) block to merge multiple elements into a unified tag for easy referencing. This simplifies the process and allows for quick access to desired information. This method is commonly used by web developers to streamline coding and improve efficiency.
User cardosocea inquired about the MDI tag. It took some time to figure out, as the online resources for iFix were not very clear. Nevertheless, it eventually worked. Thank you for the help.
GeoHend shared: After some trial and error, I finally got it to work. Unfortunately, the online resources for iFix weren't very clear. Nonetheless, I appreciate the assistance. I have a strong distaste for iFix, but I must admit that the PDB offers some intriguing functionalities every so often. Keep in mind that not all installations may include the MDI block, so you may have to add it yourself. Recently, I've been excited about the PAR block, as it has proven to be quite handy for translations and dynamic animations.
Sure, you can certainly achieve this using scripting. In most SCADA systems, you should be able to use a script to monitor the states of both tags and then trigger an alarm graphic based on their conditions. This way, the graphic would appear as an alarm indicating when both tags are inactive. However, it’s always beneficial to ensure you have the proper permissions from your contractor to make any alterations as it may affect the overall operation of your equipment. One should always proceed with caution while dealing with externally managed resources, just to avoid any unintentional hassles.
Absolutely, you can definitely achieve this by using scripting. You can create a transparent object whose visibility is tied to the status of both tags. For instance, when 'tag1' & 'tag2' = 0, the object becomes visible. This object displays your desired alarm graphic. However, the specifics of the scripting will depend on the software platform you're using. If you could share that information, I'd be happy to provide a more detailed procedure or even a script sample.
It sounds like an interesting project! Since you're limited by not having PLC access, you could consider using JavaScript if your banner allows customizable scripting. You could regularly poll the status of the tags via an API (if available) or any existing endpoints to check their state. If both tags return inactive, you can dynamically update the banner to display your alarm graphic. Just make sure to account for any potential delays or refresh requirements to ensure the UI responds promptly! Good luck!
That sounds like an interesting challenge! Since you can’t access the PLC directly, one way to approach this could be through a web-based solution if your banner is displayed on a webpage. You could use JavaScript to check the status of the tags through a backend service or API that reports their state. When both tags are inactive, you can trigger a function that displays your alarm graphic in the banner. Just make sure to create a polling mechanism or subscribe to a relevant event if the tag status can change. Good luck, and it’ll be great to see how it turns out!

Answer: - You can create a graphic that appears when both tags are not active (tag1 + tag2 = 0) by utilizing scripting in iFix.
Answer: - Yes, you can use scripting to trigger an alarm in the top banner when both tags are not active.
Answer: - Since you don't have access to the PLC, implementing the alarm directly in the PLC code may not be feasible. Using scripting in iFix could be an alternative solution.
Answer: - If you had access to the PLC, creating a new tag in the PLC code would have been a direct way to implement the alarm system, but since you don't have access, utilizing iFix with scripting is a viable option.
