Description
Use as a master station in the CC-Link IE Field Network.
Use as a local station in the CC-Link IE Field Network.
Description
This mode performs cyclic transmission and transient transmission without losing their inherent speed performance.
This mode is suitable for a system that performs I/O control and analog control, and transmits large amount of data for
management, monitoring, and diagnostics by transient transmission. Use this mode for general applications.
This mode preferentially performs cyclic transmission for high-speed communications. This mode is suitable for a
system to achieve I/O control, analog control, and digital I/O at high speed.
Note that the maximum points assigned to RWw/RWr is 256 points per local station.
In this mode, the processing speed of transient transmission is slower than that in "Online (Normal Mode)"
Select this mode to disconnect the station from the network for stopping data link with other stations.
Description
Select this mode to connect the station to the network for performing data link with other stations.
Select this mode to disconnect the station from the network for stopping data link with other stations.
