(c) Buffer memory size specification for intelligent device station
Send buffer 64 words
Receive buffer 64 words
Automatic update buffer 128 words
POINT
(1) Perform an automatic CC-Link startup in the following settings.
Master station
Remote net Ver.1 mode
Transmission speed: 156kbps
(2) Make sure to perform loop tests by GX Works2 for all stations if an automatic
CC-Link startup is performed and changes such as replacement of a module,
etc. are made to the system during data link operation.
Stations whose data link has already been established (only stations whose
station numbers overlap) may also go down if stations with overlapping head
station numbers return to the system.
(3) If an automatic CC-Link startup was performed, a temporary error invalid
station cannot be used.
(4) The device on the LCPU in the contents of the default automatic refresh
parameter settings is changed with device points of "PLC Parameter" –
"Device" at the automatic CC-Link startup. If no refresh device exists, the auto
refresh is not performed.
If the auto refresh is not performed when the SM319 of the CPU module is in
off status, check the device points assignment of the CPU module.
(2) Execution conditions
(a) For L02CPU
When the parameters are not set, the automatic CC-Link startup function is
applicable only to one "LJ61BT11". Even when more than one LJ61BT11 is
mounted, the automatic CC-Link startup function is applicable only to the
first one. It is applied to the LJ61BT11 that has the smallest start I/O number,
as seen from the programmable controller CPU side.
(b) For L26CPU-BT
When the parameters are not set, the automatic CC-Link startup function is
applicable only to the built-in CC-Link function.
Even when LJ61BT11 is mounted, the automatic CC-Link startup function is
applicable only to the built-in CC-Link function.
It is applied to the L series master/local module that has the smallest start
I/O number, as seen from the programmable controller CPU side.
