4.4.4
Entry code registration
The entry code is used to prohibit programs and comments in
the PC CPU
from being read or rewritten with a peripheral device.
(1) Read/write from the PC CPU to which
the entry code is registered
In case the entry
code is registered, parameters, main/sub-programs
and comments can not be read or written from
the PC CPU to a
peripheral device unless the entry
code is entered to the peripheral
device.
(2) Registration and cancellation of the entry code
A maximum of 6
digits in hexadecimal (0 to 9, A to F) can be used to
set the entry code.
The entry code is registered or canceled with parameter setting.
POINT
I
In case an entry code is forgotten or in case an unknown entry code is
registered to the A2C, perform PC memory all clear by use of a peripheral
device.
If all memories of the A2C are not cleared, the A2C cannot
communicate with a peripheral device.
When PC memory all clear is executed, all of parameters and sequence
programs stored in the A2C are cleared.
