Detailed description
The method to use dedicated instructions to set the CC-Link
parameters and receive notification when the power is turned on or at
STOP RUN.
The method to write directly into the buffer memory in the module and
receive notification.
2
The method to register to the E PROM in the module and receive
notification.
RX, RY and other cyclically transmitted data can be refreshed to a
desired device through the END processing, using dedicated
instructions.
Data link can be performed using the scan synchronized with the
sequence program.
Data link can be performed using the scan not synchronized with the
sequence program.
Data communication can be performed at 32 points per station.
Data communication can be performed at 4 points per station.
Transient transmission can be performed to the intelligent device and
local station using dedicated instructions.
Device can be read from/written to the CPU of the specified station
using dedicated instructions.
Communication can be performed only with the remote I/O station
without setting parameters.
Stations to be connected later can be skipped and set in advance.
Data link error can be ignored when data link is disabled at any station.
Replacement of modules can be performed online without detecting an
error at the corresponding remote station.
Only CC-Link can be reset when changing switches, etc., without
stopping the CPU.
Stop/restart can be performed during data link.
The station which has been disconnected from data link can be
returned automatically to the data link through normal return.
Data link can be continued when an error occurs at the master station,
by switching to the standby master station.
The station at which data link has been disabled can be disconnected
so that data link can be continued using normal stations only.
The data link status can be confirmed using the special relay and
special register.
A hardware test, line test, etc., can be performed.
