Writing Bit Data to BTR Files
This section describes how to use Block Transfer Tag names to write bit data to BTR data files in the
target display.
To write bit information to a data file, you need to specify the name of the data file, the word within the
file and a bit specifier. The command format used to specify bit data is FILENAME[word]/bit.
Example: BTW0120[07]/04. In the following example, the name of the data file is BTW0120 and the
size of the file is 16 words. The example illustrates several Tag Names and their relationship to the data
file.
BTR0120
Tag Name Data File Location Bit Location
BTR0120[00]/00 Word 0 Bit 00
BTR0120[01]/02 Word 1 Bit 02
BTR0120[07]/04 Word 7 Bit 04
BTR0120[14]/12 Word 14 Bit 12
BTR0120[15]/15 Word 15 Bit 15
This command format allows you to write a bit to the data file using an operator such as a push button.
For example, when creating a push button, you are presented with a setting menu that requests a Tag
name. If you entered BTR0120[7]/04, the target display would write bit 4 of word 7 in the data file
labeled BTR0120.
