PARDAT handling on the AC 80 differs from that of the AC 70 or APC2.
The actual PARDAT values are stored in a separate segment in non-
volatile FLASH PROM.
The application program is prepared by using the FCB (Function Chart
Builder) tool. The target code is generated by selecting File –
Generate Target Code.... When connected, FCB downloads the
application program with the command Target – Load Application.
The application program is stored in the AC 80 RAM, which is also
where it is executed.
The Target – Save in PROM command creates a back-up of the
application program to User FLASH PROM. On power-down, reset, or
restart, the application program is restored to the RAM and initialised.
Depending on the value of PM825 element parameter STARTMOD, the
application program will either start automatically or remain blocked
until manually deblocked.
The NCB system program consists of the AMC boot program, NCBOS,
and the AMC table of the AC 80.
The AMC boot program resides in a PROM on a socket. It receives the
NCB software upon downloading and stores it in non-volatile FPROM.
The NCBOS consists of
• AMCOS operative system, including routing
• Communication support for DriveBus, fieldbus adapters and Special
I/O.
The NCBOS automatically adapts to communication configured in the
application program in the CPU.
Upon downloading, the NCBOS is stored in non-volatile FPROM and
started automatically. The NCBOS can be updated by downloading a
new revision; this overwrites the previous NCBOS revision.
On power-down, reset, or restart, the NCBOS in FLASH PROM is
copied to RAM and initialised.
The AMC table of the NCB contains variables and parameters which
can be accessed by the Drive Window and Drive Debug tools.
Parameter values are saved to non-volatile FPROM and restored upon
NCB reinitialisation.
