S3 Password Protection
The user must define what measures are to be applied to
protect against project changes. S 3 provides safeguards
described in the following paragraphs.
Access to the S 3 software program is restricted by
password protection. Passwords can be changed at any
time by the user with correct privileges.
S 3 supports up to 63 unique user accounts, each
capable of having a different password and access
privileges. These user accounts are controlled by the S 3
system administrator.
Configuring User Accounts
There are five parameters that are used to configure the
users account.
User Level
A user level between 0 and 65535 is used to determine
what a user can do. Each command or button that a
user can interact with in S 3 has a user level assigned to
it. The higher the number, the higher the “privileges” for
that user. A user level of “0” would allow “browsing” only
with no command capability.
Configure System Enabled
When selected, this option allows the user access to
the engineering and configuration aspects of the S 3
software suite. This includes the ability to make, move,
configure and delete ports and the ability to create or
modify points like fire detectors, gas detectors, analog
transmitters, digital inputs, etc. attached to one or more
of the available ports.
Quit “Online” Operations Enabled
When selected, the user is able to quit online operations
and return to the S 3 main screen for access to the
various engineering and maintenance utilities.
Port Diagnostics Viewing Enabled
When selected, when online the user can access
the port diagnostics screen. This screen allows the
user to view details about the operation of all active
communication ports, whether serial or ethernet. This
would typically be used by a technician responsible for
troubleshooting connectivity between the S 3 station and
any attached systems.
Restricted Access Enabled
This feature is intended to give limited access of the
EQP port configurations for viewing and documentation
purposes.
User accounts can be created with only the “restricted
access” checkbox selected, or combined with the
other checkboxes — configure system, quit online, port
diagnostics.
S3 Change Control Log
S
3 maintains a Configuration Log that records changes in
the master project file. The log can be viewed from S 3 .
A record is made in the Configuration Log when:
• IO Modules are added, deleted, or moved
• Tags are added to, removed from, or moved within an
IO Module
• IO Configuration parameters are saved
• External node numbers are entered or modified
• Serial communications parameters are entered or
modified
• A successful download is made to a Controller
• A project is removed.
S3 function Block Logic
The S
3 software allows users to customize application
software with the use of function block logic. For SIL
certified systems, SIL rated function blocks must be
used to comply with the SIL-2 certification.
The SIL rated function blocks and associated input and
output links are color coded red to help the user identify
quickly if there are any non-compliant blocks. Refer to
Appendix B for a list of available function blocks.
Clearly separate safety-related function logic from
non-interfering logic. Place all safety functions on their
own logic pages, and place all non-interfering functions
on their own logic pages.
Note
It is the user’s responsibility to test, verify and
validate all safety related custom logic for
conformance to the code.
