6 Operation
Operating Modes
SCADAPack 32P 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.
6.1 Run
Mode
The RUN mode is the normal operating mode of the SCADAPack 32P Controller. No action is
required to select RUN mode. When power is applied to the SCADAPack 32P:
•
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.
6.2 Service
Mode
SERVICE mode is used during application programming and maintenance work. When the
SCADAPack 32P controller starts in SERVICE mode:
•
The default serial communication parameters are used. See section
of this manual for a description of the 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
of this manual for the default parameters.
•
If a TelePACE or ISaGRAF application program is loaded it is stopped.
•
If an ISaGRAF 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:
•
Remove power from the SCADAPack 32P controller.
•
Hold down the LED POWER button.
•
Apply power to the controller.
•
Continue holding the LED POWER button until the STAT LED turns on.
•
Release the LED POWER button.
Note:
If the LED POWER button is released before the STAT LED turns on, the SCADAPack 32P
controller will start in RUN mode.
