Controlling User Access to Field Panel Functions
The following four access levels can be assigned to any field panel function for any
user.
No AccessUsers cannot see the function.
Read Only Users can only view the value or status of objects.
Command Users can command or display the value or status of objects.
EditUsers can add, delete, command, modify, and view objects.

If a user has a Command access level for the Point Editing function, then only the
functionality required to command a point is available to them. They do not see or have
access to the prompts required to add, modify, or delete a point definition.
For more information on user accounts and privileges, see the TALON Firmware
User's Manual (588-580) (588-580).
Customized Applications
Some TC Compact Series applications are created in the Powers Process Control
Language (PPCL). These applications use PPCL statements and additional hardware
to perform customized operations or functions in your system. Examples of
applications created in PPCL include:
Duty Cycling
Enthalpy and Dry Bulb Economizer Control
Peak Demand Limiting (PDL)
Information on how to customize these applications for your facility is included in the
TALON Powers Process Control Language (PPCL) User's Manual (588-583) and the
TALON Firmware User's Manual (588-580). These manuals are available from your
Siemens Solution Partner, Authorized TALON Dealer.
SNMP
The Simple Network Management Protocol (SNMP) Agent is a firmware feature that
has been added to BACnet Firmware Revision 3.2.3 and later. The SNMP Agent
allows points in the field panel to communicate with an SNMP manager over Ethernet.
SNMP is an application layer protocol that facilitates the exchange of management
information between network devices. It is part of the Transmission Control
Protocol/Internet Protocol (TCP/IP) suite. SNMP enables network administrators to
manage network performance, find and solve network problems, and plan for network
growth.
