CC-Link Communication and Operating Modes
The DL-CL1 operates as a remote device station of a CC-Link system.
This section describes the data that the DL-CL1 can exchange through the CC-Link,
and available operating modes.
The DL-CL1's data is linked with the CC-Link maser station as shown below.
Through the link, the CC-Link master station is enabled to:
• Communicate the output signal, current value, and error status of sensor amplifiers
without the need of a ladder program.
• Use the remote input RX and remote output RY areas as handshake signals to
execute external inputs to, or change the setting values of, sensor amplifiers.
• Execute motion commands on sensor amplifiers.
• Directly read and write the parameters of sensor amplifiers. This capability gives
the ability to use functions that can be executed on sensor amplifiers.
