When the instrument parameters have been established you may wish to password protect the settings against accidental or
unauthorised adjustment. It is possible to make individual protection for each instrument function at each level, and for each
instrument on the network
Please study the lock hierarchy diagram below before implementing your security strategy.
When correcting errors, start again from supervisor level,
lock none
, and clear the locked settings in the correct hierarchical
sequence
Supervisor
All of the controller functions are available to the supervisor
who can deny adjustment of any number of them to lower
levels in the hierarchy. These settings will be protected by
the supervisor’s password.
Operator
The operator can adjust all controller functions not locked
by the supervisor, and can in turn lock any of these to deny
adjustment to a user, and then protect them with the
operator’s password.
User
Any remaining functions are available for adjustment by the
end user. These functions can be locked and unlocked
without the use of a password.
