In the program example in this section, the following transient transmission is performed using the READ and
WRITE instructions.
(a) Processing at control station (No. 1)-side
1. D300 to D349 of the normal station (No. 2) is read to D800 to D849 of the control station (No. 1) with
the READ instruction.
2. D900 to D949 of the control station (No. 1) is written to D400 to D449 of the normal station (No. 2)
with the WRITE instruction.
(b) Processing at normal station (No. 2)-side
A sequence program of the normal station (No. 2)-side is not required.
