transferred is specified by the number of memory units of the data written to the remote PLC
(Word 17).
(Word 14) Local PLC - Memory Starting Address:
Word 14 determines the starting address in
the local PLC from which the data is to be written. 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.
(Word 15) Remote PLC - Memory Type:
Words 15–16 specify the memory type and starting
address in the remote PLC where the data is to be written. Valid values for Word 15 are listed
under Establish Read Channel. 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 where the data is to be written. 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.
(Word 17) Remote PLC - Number of Memory Units:
Word 17 specifies the amount of data to be
transferred. The value entered is the number of memory units to be transferred, where the size of
a memory unit is either a bit, byte, or word as specified in Word 15. For example, if Word 15=16
and Word 17=4, then 4 bytes (32 bits) of %I memory will be transferred. The user is responsible
for assuring that this area is large enough to contain the requested data without overwriting other
application data.
For the Series 90-30 PLC, a maximum of 8192 bits, 1024 bytes, or 512 words of data can be
specified.
For the Series 90-70 PLC, a maximum of 16384 bits, 2048 bytes, or 1024 words of data can
be specified.
