2.1 0 6ES5 242 Module Memory Map
Setting of the physical address of the 6ES5-242 module was
discussed in an earlier section. In that section the subaddress
was shown to have 16 possible addresses. This section will
map out these 16 subaddresses.
Direct reading and writing operations to the module are
accomplished through peripheral words (PWxx). This is
particulary useful when you need to develop a "custom"
software function. See Chapter 4 for detailed information on
Standard Software Blocks. Exercise extreme caution when
using this feature with standard software, as these two opera-
tions may interfere with each other.
