11 Operation
11.1 Operating Modes
SCADAPack 32 Controllers may start up in RUN, SERVICE or COLD BOOT mode. Start up in the
RUN mode automatically executes the application programs in the controller memory. Start up in the
SERVICE mode stops the programs to allow reprogramming and controller initialization. Start up in
the COLD BOOT mode initializes the controller and erases all programs.
11.1.1 Run
The RUN mode is the normal operating mode of the SCADAPack 32 Controller. No action is
required to select RUN mode. When power is applied to the controller board:
• The user defined serial communication parameters, for all COM ports are used.
• The user defined TCP/IP and Modbus/TCP parameters are used for the Ethernet port.
• If a TelePACE or ISaGRAF application program is loaded it is executed.
• If a TelePACE or ISaGRAF C/C++ application program is loaded and the program checksum is
correct, it is executed.
• The controller lock settings and password are used.
11.1.2 Service
SERVICE mode is used during application programming and maintenance work. When the
SCADAPack 32 controller starts in SERVICE mode:
• The default serial communication parameters are used. See section 9.1-RS-232 Serial
Communication Ports above subsection for default parameters.
• The user defined TCP/IP parameters are used for the Ethernet port.
• The default Modbus/TCP parameters are used for the Ethernet port. See section 10.1.2-
Modbus/TCP Settings for default parameters.
• If a TelePACE or ISaGRAF application program is loaded it is stopped.
• If a TelePACE or ISaGRAF C/C++ application program is loaded it is stopped.
• All programs are retained in non-volatile memory.
• The controller lock settings and password are used.
SERVICE mode is selected by performing a SERVICE BOOT using the following procedure:
1. Remove power from the controller.
2. Hold down the LED POWER button while applying power to the controller.
3. Continue holding the LED POWER button until the STAT LED turns on.
4. Release the LED POWER button.
Note: If the LED POWER button is released before the STAT LED turns on, the SCADAPack 32
controller will start in RUN mode.
11.1.3 Cold Boot
COLD BOOT mode is used after installing new controller firmware. When the SCADAPack 32
controller starts in COLD BOOT mode:
