* The limitation in a flash-ROM designates the number of rewrites to be
14
10,000, or the feasible number to be approx 30,000. However, rewriting
every second will generate a memory failure within a few hours.
The built-in 512kb flash-ROM can store a 32-k step pro-
gram as well as the comments and FPWIN Pro source
file.
Program update in a remote location is easy by simply
sending master memory for local installation.
As the master memory stores the password informa-
tion, password protection can be applied for program
transmission. Similarly, upload prohibition/permission
can be set up.
The built-in real-time clock enables periodical repeated
control and periodical data logging.
The programs and comments are stored in flash-ROM
requiring no backup batteries.
A backup battery (AFPX-BATT) is provided for data
and the real-time clock. 1 battery for C14, 2 for C30
and 3 for C60 can be attached. A 2-battery installation
can operate for a long time (10 years or more) without
maintenance. (The real-time clock does not work with-
out a battery.)
FP-X can store a program, comments, a total of 55
words of data and bit setting values in a flash memory
without a battery. All of the data and bits can be stored
by adding optional batteries, but writing into a flash-
ROM is possible without a battery by using applied in-
structions (F12, P13). Perfectly suited for data storage
of the setup values and recipes modified several times
a day. *
The master memory makes program transfer easy, and a real-time clock is also included
Programs can be saved without a backup battery, making maintenance easier
