3Ć1 Theory of Operation: Operating States
Original Ć June 1990 CE4.2:CL6211
3 Theory Of Operation
3.1 Operating States
3.1.1 Database Hold
A Regulatory Controller may power up in a state termed Database Hold"
or No Configuration", which simply means that the controller has not
been loaded with a user configuration. A user configuration is required
to allow the device to perform the desired algorithm(s). A Regulatory
Controller in Database Hold is indicated by error -7-" on an Operator
Station, or the Unavailable" integrity error on an operator's console. To
correct this condition, the user must download the desired configuration
to the controller (see section NO TAG on page NO TAG for details
concerning Upload/Download).
A controller may enter the Database Hold state under the following
conditions:
H When first powered up after being received from the factory;
Recovery - See the Installation/Maintenance manual
H After being un-powered for a time period exceeding 24 hours;
Recovery - See the Installation/Maintenance Manual
H After rejecting an attempted user download that exceeds the capacity of
the device (either a configuration error was detected during download, or
the device limits, such as available RAM, have been exceeded).
Recovery - The user should correct the configuration error, or reduce
the size of the configuration, and re-attempt the download.
3.1.2 Normal Processing
After the controller has received a successful download of the user's
configuration, the controller enters the Normal Processing state. In this
state, all of the normal controller functions are performed, such as point
processing (input and output scanning, and control algorithm
processing), communications processing, and self test operations.
