(2) Irregular communication (Transient transmission) ( Page 94, Section 4.2)
(a) Communications with a programmable controller on another station
Using a link dedicated instruction, data can be read from or written to a programmable controller on another
station.
Communications with programmable controllers on other networks are also available.
(b) Large-volume data communications
By using link dedicated instructions (READ/SREAD/WRITE/SWRITE), large-volume data communications are
achieved.
The instructions are useful for irregular and large-volume data communications.
One link dedicated instruction execution can read or write data of up to 8192 words from/to a programmable
controller on another station.
To specify 961 words or more, use channel 9 or 10 of the own station.
