Logical Addressing for Report Generation
Chapter 6

Extended addressing can access any area of PLC–3 memory. In extended
addressing, you enter E followed by the memory area. Then you enter
parameters, or levels that the memory area requires, seperated by periods
to specify a memory address to the bit level if necessary. For example, if
you are specifying a data table address, you follow the $ sign with E3 to
specify the data table. Then you must enter a context number, data table
section, file number, structure, word and/or bit. Table 6.B outlines the
memory areas along with required parameters.
