Data Table Area Configuration
The data table is factory-configured for 128 words (Figure 3.2). The data
table size can be decreased to 48 words or expanded to 8,064 words (with
8K memory) or 8,192 words (with 16K memory). Expanding the data table
provides additional timers/counters and space for files.
NOTE: In expanded areas, care must be taken to prevent files from writing
over timer/counter preset values or your program. We recommend that
you program all timers/counters in the first expanded areas and that you
program files after them in a separate expanded area.
Configuring The Data Table
You must configure the final data table size in processor memory before
entering your program. This is done by entering the number of 128-word
data table sections and, if necessary, the number of equivalent timers and
counters.
