When [Specify Text File Number] is [Constant]
Text File Number
Set a text file number for the text from 1 to 8,999.
Start Row Bit Address
Set the start bit address to store the text display's start row specification data. You can set a bit address or a word address to specify bits.
The display start row is determined by the data stored in the range of the start row to the bit specified in [Number of Bits] and the [Rows Scroll].
Number of Bits
Sets how many bits, from the [Start Row Bit Address], are used for Display Start Row Specification. Select a value from 1 to 16. The number of bits to use will differ depending on the specified [Rows Scroll].
For example, 12 rows of text will be scrolled by 4 rows each time = using 2 bits
Because the number of bits used is set from the Display Start Row Specification data, the empty portion of the Reserved Area can be used for other purposes.
For example, Start Row Bit Address = D100 8 bit, Number of Bits = 4
When setting the [Number of Bits], please ensure that the allocated bits are in one word. Even if the number of bits is set to span across two words, only the address specified in [Start Row Bit Address] will be allocated as the Display Start Row.
For example, Start Row Bit Address = D100 12 bit, Number of Bits = 10
Set the number of rows the display scrolls from 1 to 256 when the Start Row data changes.
Display Start Row = Rows Scroll (Display Start Row data -1) +1
For example, [Display Rows] = 4, [Rows Scroll] = 4
Display Start Row data = 1Display Start Row = 1
Display Start Row data = 2 Display Start Row = 5
Display Start Row data = 3 Display Start Row = 9
If the Display Start Row is "0", the text does not display, and the Message Display's Display Area is shown with a transparent color.
