Cyclic transmission Increase of cyclic transmission data size Transient transmission Less restrictions on the station-to-station cable length 1.3 Features The features of the CC-Link are described below. (1) Remote I/O station communication The ON/OFF status of a switch or indicator lamp is communicated using the remote input RX and remote output RY (see Section 4.2.1).
Page 21 1 OVERVIEW MELSEC-Q (2) Remote device station communication Signals for handshaking with the remote device station (initial request, error occurred flag, etc.) are communicated using the remote input RX and remote output RY. The setting data to the remote device station are communicated using remote registers RWw and RWr (see Section 4.2.2).
Page 22 1 OVERVIEW MELSEC-Q (3) Local station communication Communication between the master station and the local station uses two types of transmission methods: cyclic transmission and transient transmission (see Section 4.2.3). (a) Cyclic transmission Data communication between the PLC 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).
Page 23 1 OVERVIEW MELSEC-Q (4) Intelligent device station communication Communication between the master station and the intelligent device station uses two types of transmission methods: cyclic transmission and transient transmission (see Section 4.2.4). (a) Cyclic transmission Signals for handshaking with the intelligent device station (positioning start, positioning complete, etc.) are communicated using the remote input RX and remote output RY.
Page 24 1 OVERVIEW MELSEC-Q (5) Parameter setting by GX Developer or the dedicated instruction There are two parameter setting methods; the parameters can either be set by GX Developer or by using a dedicated instruction (see Sections 2.2.1, 4.2.5 and 4.2.6).
