(3) Local station communication
The local station is a station having a programmable controller CPU and the
ability to communicate with the master and other local stations.
Communication between a master station and a local station uses two types of
transmission methods: cyclic transmission and transient transmission (refer to
Section 8.1.3).
(a) Cyclic transmission
Data communication between programmable controller CPUs can be
performed in N:N mode using bit data (remote input RX and remote output
RY) and word data (remote registers RWw and RWr).

(b) Transient transmission
Read (G(P).RIRD) or write (G(P).RIWT) operation of the local station buffer
memory and CPU device can be performed at any timing.
