Double position controller with synchronizing-checking (DPSY)
The double position controller with synchronizing-check (DPSY†) function is used when the
user wishes to control a device from the "Closed" or "Open" condition. Generally, the device
controlled by the DPSY function is either a 43-switch or a CB. The DPSY function has two
measurements: an operation counter and an operation timer. The two features are useful when
the user wishes to assess the operating time of the device and the total service duration in the
operated state; these features are performed by counting the state-changes for the device.
†Note: The DPSY function is similar to the DPOS function; the DPSY function is required
to operate together with the synchronizing function (SYNDIF), which has relay
elements corresponding to voltages, and can coordinate the timing for closing or
opening. For more detailed information with regard to the SYNDIF function, see
Chapter
network
The BO circuits are used for issuing commands; the BI circuits are used for receiving
responses; hence, the user should set the BIO† together with the DPSY function. The DPSY
function includes three logic groups: 1. Selection logic, 2. Cancel logic, and 3. Operate logic.
Tips: If the user wishes to apply the DPSY function quickly, go to sections 4.2.6 and
4.2.7, where setting of the BI and BO circuits and the mapping of signals for
IEC61850 communication is described.

Note:
The implementation of such features depends on the selection of hardware and the
configuration of functions. Several IED models do not have its features. To determine whether
its features are implemented in the IED, locate the IED ordering number; and check the order
number at the "G&T position" referring to the comparison table below. For more information,
