Memory Allocation
Section 4-2
64
The Range/Comparison Data, as part of the Unit configuration data, is transferred
to the Unit at Power Up or after the Unit has been restarted.
The least significant word (LSW) of the Indirect Address contains the four least
significant digits and the most significant word (MSW) contains the most signifi-
cant digit of the Indirect Address (refer to section the examples on the following
pages).
Example Range Mode
Unit is in Range Mode. You want to use 3 Ranges (Range 0 to Range 2) for Coun-
ter 1 and want to allocate them in Data Memory starting from D1850.
For an overview all addresses related to Range Data refer to section 4-2-5
