If the “Storage Space Insufficient” message pops up on the HMI screen (Window number 8 in EBPro), it is likely caused by not having a USB flash drive or SD card connected to the HMI when the Event/Alarm log or the Data Sampling Object is configured to save data to one of these memory devices.…

When using a Maple Systems HMI, the project, recipe (RW, RW_A, db), data log, event log, and operation logfiles are stored in permanent HMI (flash) memory. There are several ways to clear data in flash memory.
Yes. You can dynamically change the address referenced by an object using the index feature. This allows you to create and indirect pointer or offset into PLC or HMI memory. In the object properties window click on the address settings button then check the Index register checkbox and select the index to use. When you…

There are two options for trending data in MAPware7000. Both of these objects can be found in the “Advanced Objects” menu. Real Time Trend: The Real Time Trend is used to display a trend graph that represents up to four tag registers. The graph polls the registers on a timed basis and displays the values as plots…
There are several ways to accomplish this. To set a few registers or bits you can place Set Bit or Set Word objects on the common window (window #4). These objects have an option for Set On when window opens: Because the common window is always visible objects placed on this screen will be triggered…

This depends on the driver. Some drivers will allow you to configure the word order globally for the driver. This would be done from a Data Conversion button on the Device Settings window. In EBPro go to <i>Home > System Parameters > Device > Settings… > Data Conversion. The Modbus driver has options to swap…

When you want to read 32-bit register using a word addressed protocol like Modbus all you have to to is set the format to a 32-bit format (32-bit signed, 32-bit unsigned, 32-bit float) on the format tab of your object. The HMI will take care of reading the correct number of registers.

Method 1: The GetData and SetData functions can be used to transfer data from one tag to another in a macro. Use GetData to grab the value from one tag and store it in a variable, then use SetData to move the data from the variable into the other tag. Use the Get/Set FN tool…

For PLCs with fixed addressing like the Allen-Bradley MicroLogix Series, data must be stored in consecutive registers in order to sample multiple data points and store the data in a single datalog file so that multiple channels can be displayed in a Trend Display or History Data Display. For tag-based PLCs like the CompactLogix, create…

The PLC Control object in EBPro is a feature in the software that can execute commands when it is triggered by a PLC bit or word. Click [Object] » [PLC Control] icon on the toolbar to open the PLC Control Object management dialog box. To add a PLC Control object, click [New], set up the…
Microsoft® SQL Server can be used with our High Performance series to help collect and display data for easier monitoring and analytics. The High Performance series also support a built-in database query viewer which enables production machines to retrieve data from your central SQL database. By connecting a High Performance HMI product to an SQL…

Security settings in EBPro allow you to disable or password protect project uploads from the HMI, disable or password protect de-compilation of the project file, and password protect the project file itself. These features are discussed in more detail in the Security chapter of the EBPro Programming Manual.
