Access Control
Each acyclic PROFIBUS connection has an access level that can be changed by providing PIN
information via the parameters USER_PIN and / or EXPERT_PIN
•
Each parameter has a protection level assigned that specifies the required access level to modify
the parameter via an acyclic PROFIBUS connection.
•
If the access level of the acyclic PROFIBUS connection is smaller than the protection level of the
parameter that is desired to be modified, then the attempt to modify the parameter is rejected
by the device.
The following access levels are provided:
Access level
Description
READ ONLY
Having this access level, the acyclic PROFIBUS master is not able
to modify the device configuration (setup parameters). The
PROFIBUS master is only able to execute commands, e.g. start
dosing and reset totalizers.
USER
Having this access level, the PROFIBUS master is able to modify
a subset of the device configuration. The PROFIBUS master has
to provide the correct end user password to the parameter
USER_PIN to reach this access level. The initiator is a
“normal”
user in the plant not having access to critical parts of the
configuration.
EXPERT
Having this access level, the PROFIBUS master is able to modify
the configuration of the device. The PROFIBUS master has to
provide the correct service user password to the parameter
EXPERT_PIN to reach this access level. The initiator is either a
service user at the plant (not TRICOR service personnel) or
TRICOR service personnel.
