5.5.2. 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 con gured digital inputs and
outputs. The number of controllable and monitored objects in each relay depends on the available
inputs and outputs. 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 by local control, by remote control, by an HMI mimic manually, or by a
software function automatically. The function supports the modes "Direct control" and "Select before
execute" while controlled remotely.
Object control consists of the following:
control logic
control monitor
output handler.
In addition to these main parts, the user can add object-related circuit breaker failure protection
(CBFP; 50BF) and object wear monitoring in the object control block. These additional functions are
not included in the basic version of the object control block.
The 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 use 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
the OBJECT READY and SYNCHROCHECH monitor signals.
Withdrawable cart IN and OUT status signals.
The function generates general time stamped ON/OFF events to the common event buffer from each
of the two (2) output signals as well as several operational event signals. The time stamp resolution is 1
ms. The function also provides a resettable cumulative counter for OPEN, CLOSE, OPEN FAIL, and
CLOSE FAIL events.
The following gure presents a simpli ed function block diagram of the object control and monitoring
function.
