2.3 Characteristics
This section describes the characteristics of the CC-Link.
1) Communication with remote I/O station
The switch ON/OFF status and the lamp ON/OFF status are communicated using remote
inputs (RX) and remote outputs (RY).
Remote inputs (RX) and remote outputs (RY) are assigned to the buffer memory (BFM)
numbers built in the FX
2N
-16CCL-M. (Refer to Subsections 4.6.6 and 4.6.7.)
*1 Devices which can be specified as FROM instruction transfer destinations or TO
instruction transfer sources can be used.
2) Communication with remote device station
Handshake signals (such as initial requests and error occurrence flags) are communicated
with remote device stations using remote inputs (RX) and remote outputs (RY).
The setting data and other data are communicated with remote device stations using
remote registers (RWw and RWr).
Remote inputs (RX), remote outputs (RY) and remote registers (RWw and RWr) are
assigned to the buffer memory (BFM) numbers built in the FX
2N
-16CCL-M. (Refer to Sub-
sections 4.6.8 and 4.6.9.)
*1 Devices which can be specified as FROM instruction transfer destinations or TO
instruction transfer sources can be used.
