5.5.3 Object control and monitoring
The object control and monitoring function takes care of both for circuit breakers and disconnectors.
The monitoring and controlling are based on the statuses of the relay's configured digital inputs and
outputs. The number of controllable and monitored objects in each relay depends on the device type
and amount of digital inputs. One controllable object requires a minimum of two (2) output contacts.
The status monitoring of one monitored object usually requires two (2) digital inputs. Alternatively,
object status monitoring can be performed with a single digital input: the input's active state and its
zero state (switched to 1 with a NOT gate in the Logic editor).
An object can be controlled manually or automatically. Manual control can be done by local control, or
by remote control. Local manual control can be done by relays front panel (HMI) or by external push
buttons connected to relays digital inputs. Manual remote control can be done through one of the
various communication protocols available (Modbus, IEC101/103/104 etc.). The function supports the
modes "Direct control" and "Select before execute" while controlled remotely. Automatic controlling can
be done with functions like auto-reclosing function (ANSI 79).
Object control consists of the following:
• control logic
• control monitor
• output handler.
The main outputs of the function are the OBJECT OPEN and OBJECT CLOSE control signals.
Additionally, the function reports the monitored object's status and applied operations. The setting
parameters are static inputs for the function, which can only be changed by the user in the function's
setup phase.
The inputs for the function are the following:
• digital input status indications (the OPEN and CLOSE status signals)
• blockings (if applicable)
• the OBJECT READY and SYNCHROCHECK monitor signals (if applicable).
• Withdrawable cart IN and OUT status signals (if applicable).
