(Word 13) Local PLC - Memory Type: Words 13–14 specify the location in the local PLC where the Ethernet
Interface will store data received from the remote PLC. Valid values for Word 13 are listed below. The amount
of data to be transferred is specified by the number of memory units of the data read from the remote PLC
(Word 17).

(Word 14) Local PLC - Memory Starting Address: Word 14 determines the starting address in the local PLC in
which the data from the remote PLC is to be stored. The value entered is the offset (1-based) from the
beginning of PLC memory for the memory type and mode specified in Word 13. This offset will be either in bits,
bytes, or words depending on the mode specified (for example, if Word 13=16 and Word 14=2, then the starting
address will be %I9). Valid ranges of values depend on the PLC's memory ranges. The user is responsible for
assuring that this area is large enough to contain the requested data without overwriting other application
data.
(Word 15) Remote PLC - Memory Type: Words 15–16 specify the memory type and starting address in the
remote PLC from which the data is to be read. Valid values for Word 15 are listed above. If %P memory is used,
you must specify a Program name in Words 24–27. If %L memory is used, you must specify a Program name in
Words 24 –27 and a Program Block name in Words 28–31.
(Word 16) Remote PLC - Memory Starting Address: Word 16 determines the starting address in the remote
PLC from which the data is to be read. The value entered is the offset (1-based) from the beginning of PLC
memory for the memory type and mode specified in Word 15. This offset will be either in bits, bytes, or words
depending on the mode specified (for example, if Word 15=16 and Word 16=9, then the starting address will be
%I65). Valid ranges of values depend on the remote PLC's memory ranges.
