Operand types and descriptions
The following tables of Logic Operands, taken from Function Code FC134B in the 3 Series
Communications Guide, show the list of available Logic Inputs. Where specific event
descriptions are not given, a general description applies as follows:
General descriptions of operands originating from protection, control, and monitoring
elements:
The function setpoint of the element has been programmed as "Trip" and the element picked up
The function setpoint of the element has been programmed as "Trip" and the element operated
The function setpoint of the element has been programmed as "Trip" and the element operation
dropped out
The function setpoint of the element has been programmed as "Alarm" and the element picked up
The function setpoint of the element has been programmed as "Alarm" and the element operated
The function setpoint of the element has been programmed as "Alarm" and the element operation
dropped out
The operation of the element has been blocked
General descriptions of operands originating from digital elements such as contact, virtual
and Remote inputs, Output Relays, and Virtual Outputs:
"The status of the selected input or output is OFF
"The status of the selected input or output is ON
Event Description
Generated upon operation of any element with function setpoint set to "Trip"
Generated upon operation of any element with function setpoint set to "Alarm"
Generated upon detection of pickup status from any element
Generated when the operation of any element is blocked
Generated when the operation of any element is inhibited
Defines the status of the breaker in the power system. BKR Connected means breaker
