2.11 Access Control
If the flowmeter is ordered with custody transfer (CT), and the CT write protection DIP switch
is ON, the device will reject all write requests to CT parameters independent of the access
control. See the operation manual for further CT information and write protected parameters
● 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 config‐
uration of the device. The PROFIBUS master has to provide the correct serv‐
ice user password to the parameter EXPERT_PIN to reach this access level.
The initiator is either a service user at the plant (not Siemens service person‐
nel) or Siemens service personnel.
