Customizing Maintenance Intervals on HMI for Optimal Equipment Monitoring

Question:

Hey there! I am currently working on a project that involves utilizing an Allen-Bradley 1769-L30ER v31 along with a Panelview Plus7 v11. One of the key features of this project is an AOI that monitors the operational time of equipment and sends a notification when a specific maintenance interval is reached. To accommodate changes in equipment, I am looking to empower the plant manager to customize the names of these preset maintenance intervals directly on the HMI interface. For instance, they could rename "Grease Bearings" to "Change Gearbox Oil." My concern is whether this customization process is feasible or if it will pose more challenges than benefits. Alternatively, I could assign generic names like "TMR Scheduled Maintenance 1 and 2," but that may require the manager to maintain a separate legend or schedule. (For added context, the project involves a farmer-operated feed mill.) Any advice on this matter would be highly valued.

I may need some clarification on your explanation, but I'd like to offer my input. Are you storing the message in the PLC as a string or using a multi-state indicator to read an integer datatype for the message text? To achieve your goal, consider creating an array in the PLC as shown in attachment 68239. This array can be used by an alarm configuration page on the HMI to display each reason as text, along with a string input box for editing the Maintenance Reason (see attachment 68238). If you need more information or clarification, feel free to ask. Additionally, you can use a similar method to adjust timer values for maintenance alarms, allowing for flexibility in changing equipment and maintenance schedules. By using variables and mathematical conversions, you can easily modify trigger durations and write commands to the PLC for each alarm.

Baxterr expressed some uncertainty about fully understanding the explanation but offered a contribution. The query was whether the message is stored as a string in the PLC or if a function like a multi-state indicator is used to read an integer data type from the PLC to determine the message text. To achieve the desired outcome, creating an array in the PLC is suggested. This array can be utilized in an HMI alarm configuration page to display each reason in text, along with a string input box for editing the Maintenance Reason. Additionally, a similar process can be applied to adjust timer values that trigger maintenance alarms to accommodate changing equipment and schedules. Using variables in timers instead of fixed numbers, mathematical conversions can be made between milliseconds, seconds, minutes, and hours, with write commands sent to the PLC for each alarm trigger duration adjustment.

I want to express my gratitude for your suggestion, as it really pinpointed the issue. After running a test application, I was pleased to see that it performed exactly as I had envisioned.

We are pleased to provide assistance. It's great to be of help!
