4.4. Permissions
4.4.1. Register Access
Each register has permission levels required for reading, writing and executing.
These permission levels can be read using the CMD_READ_PERMISSION
command. The communications link has a permission level. Changing the current
permission level is achieved by writing a passcode to a permission register. If the
correct passcode has been given, future messages use that permission level. The
passcodes for SAFE and FULL are also used for SPEC:SAFE.PC and
SPEC:FULL.PC in the indicator’s setup menus. If more than one passcode register
has the correct passcode, the indicator uses the highest level (most powerful). The
instrument has the following permission levels:
Permission
Level
Description Passcode Register
None Lowest level permission.
Operation is always available
(eg. reading the gross weight).
NONE
Safe Operation is available if the safe
passcode has been given. Used
for indicator settings that do not
affect trade certification of indicator
(eg. baud rate).
REG_ENTER_PASS_SAFE
Full Operation is available if the FULL
passcode has been given. Used
for trade critical indicator settings
(eg. decimal places).
REG_ENTER_PASS_FULL
Factory Operation is available only to the
indicator’s internal operations
(eg. writing to the gross weight).
N/A
If a command cannot be performed because the register needs a higher
permission, the command will return an error code of
REG_ERR_ACCESS_DENIED.
