Saving and Compiling a Processor File
9–5
Disallow
:
The processor performs run-time checks on indexed addresses to ensure
that the indexed address is contained within the same data file as the base address.
This is the default selection.
SLC 5/03 OS301, OS302 and SLC 5/04 OS400, OS401 processor specific –
When an indexed string data file is specified, indexed addressing is not allowed to
cross a string element boundary, regardless of your index checking selection. A
run-time error will occur if you use an offset value that results in crossing a string
element boundary.
[F4] File Protection (SLC 5/02 Processor)
This function key toggles between Outputs, None, and All. This option allows you
to protect your data table files from external modification by devices on the DH-485
network.
Outputs: Only the output file (O:0) is protected from external data modification.
This is the default selection.
None: External devices may change any data address within the data file, including
the output file (O:0).
All: The entire data table is protected from external data modification.
[F5] Force Protection (SLC 5/03 and SLC 5/04 Processors)
This function key toggles between Enable and Disable. This option prevents a user
from enabling forces in the program. However, you can add, delete, or disable
forces. You must enable this option before downloading a program.
Enable: Forcing is not allowed and the processor indicates that it did not perform
the requested action.
Disable: Allows forcing to occur. This is the default state.
[F6] Future Access (All Processors)
This option allows you to protect proprietary program data and algorithms. The
protection takes effect only after the processor file is downloaded to a controller.
The protection does not allow online access to the processor unless a matching copy
of the online processor program is resident on the hard disk or in the Hand-Held
Terminal (HHT).
