Issue
In EcoStruxure Machine SCADA Expert, is it possible to create and trigger Alarm events with the individual 16 bit states from a WORD/Integer address?

Resolution
There is no direct way to create single Alarms from the individual 16 bits from inside an Integer (Word).
However, there is a way to extract the Boolean data from the WORD and put it into 16 individual Bit Tags (or an array of them).

Example:
If we had a WORD Tag called "iMyInteger" that we would like to create 16 Alarms from each of the bits from the WORD, we can create an Array of Boolean Tags called "myBoolArray" (with indexes 0 to 15) to be the Alarm bits and use a VBScript to move the data from the Integer Tag to the Array of Boolean Tags.

Steps:

1. Create a Tag representing the Integer in the Driver Sheet (Note: the I/O Address in the screenshot shows a Modbus TCP address)
2. Create a Boolean Array of size 16 (note that you put in the Max value of the array which is '15' starting from 0 in the Project Tag list below.
   
   
3. Create an Alarm Sheet using the Boolean Array (each index for each Alarm) and write in your appropriate Alarm Message.
4. Create a New Script under Tasks->Script that assigns the value of each bit from the Integer into each array of the Boolean Array Variable with the syntax shown in the screenshot below.
   

For projects with many Integer Tags, one can lay out the Boolean Tags and VBScript code in Microsoft Excel and copy-paste them from Excel into any Worksheet in EcoStruxure Machine SCADA Expert (that looks like a table from Excel).
Attached to this FAQ is an Excel spreadsheet that can generate the Boolean Tags as well as the VBScript for multiple Integer Tags into multiple Arrays of Boolean Tags:
