Numeric objects in EBPro have the option of using a Macro subroutine to scale the value displayed from the actual value stored in the read register. First, open the properties of the numeric object and navigate to the Format tab. Take note of the Device data format. The Macro subroutine must have the same data…
Our Macro Reference Manual provides a great deal of information and examples for programming Macros. We highly recommend reviewing the Manual, which can be downloaded from our Support Center here: https://maplesystems.com/support-center/manuals-guides There is also a very helpful tutorial video on building macros here, which features examples of declaring a variable and programming various statements:
There are no macro instructions that allow a macro to directly interface with table data in a SQL database. The data would need to be copied from the database into local HMI memory before it can be accessed by the macro, which is tedious if large amounts of data need to be manipulated. It is…
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…
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…
PLW and PLB memory cannot be used in macros. This is because macros only run on the host and do not run in separate instances on each of the clients.
The Free Protocol driver along with Macro commands can be used to send and receive ASCII data on an HMI. The OUTPORT macro function is used to send an ASCII string out of your HMI’s serial port, and the INPORT macro function allows you to receive an ASCII string to your HMI. Examples of both…
