How to clear HMI memory
Tags: Alarm Data FTP Recipe

When using a Maple Systems HMI, the project, recipe (RW, RW_A, db), data log, event log, and operation log files are stored in permanent HMI (flash) memory. There are several ways to clear data in flash memory.

 

1. Open Utility Manager, select the HMI series being configured in the upper-left corner, click [Publish] and then click [Download]. Select [Ethernet] or [USB cable]. Select all the check boxes at the bottom of the dialog to reset memory locations in the HMI.

 

2. Open project in EBPro, click the Home menu [Download PC -> HMI] and then select [Ethernet] or [USB cable]. Select all the check boxes at the bottom of the dialog to reset memory locations in the HMI.

 

3. Press the button on the lower-right corner of the HMI screen, select System Settings, enter default password 111111 or user-defined password. Go to [History] tab and check [Clear Recipe], [Clear Event log], and [Clear Data Log] check boxes and then click [Clear]. When finished, click [OK].

 

For the cMT Series, press the orange Start button in the upper-left corner of the screen to enter the System Settings window. Enter the system password (11111), then scroll down to [Clear History].

 

4. Use the following system registers to clear data on HMI:

LB-9022: Delete the earliest event log file on HMI memory (set ON)

LB-9023: Delete all event log files on HMI memory (set ON)

LB-9025: Delete earliest data sampling files on HMI memory (set ON)

LB-9026: Delete all data sampling files on HMI memory (set ON)

LB-9028: Reset all recipe data (set ON)

 

5. Log in to the HMI as an FTP server (see Technical Note 5090 – Accessing the FTP Server in the HMI). Use the “Windows Explorer” method described in the Tech Note to delete files from HMI memory.
