All Four Channels Scaled
To scale all four channels, enter a block length of 00 and enter the
appropriate scaling values for the four channels, as shown in the
following table.

Block Transfer Boundary Word Ć PLCĆ2 Family Processors Only
The purpose of the boundary word is to tell the processor not to
search for additional block transfer addresses.
You set the boundary word by entering one word (16 bits) of zeros in
the timer/counter accumulated value area of the data table, after the
word containing the last block transfer module address.
For example, if the last block transfer data address in the
accumulated value area of the data table is 035, the block transfer
boundary word is addressed as 036. Figure 4.8 shows the data table
structure and a sample GET/PUT instruction used to program a block
transfer boundary word.
