Single position device function (SPOS)

The single position device function (SPOS) is used when the user wishes to control a device

from On or Off state. When a select command is provided for the IED, the SPOS function can

issue a control command if the SPOS function obtains the response from the device. The SPOS

function also can accept a cancel command after issuing the selection command. In the SPOS

function, issuing and receiving a command and a response are performed via a binary IO

module †; hence, the user should connect the BI and BO circuits with the SPOS function. The

SPOS function includes three logic groups: 1. Select logic, 2. Cancel logic, and 3. Operate logic.

A number of devices can be controlled separately, i.e. the SPOS function has separate sets

of logic for control (i.e., SPOS01, SPOS02 etc. functions). For simplicity, only the SPOS01

function is discussed here; the features in the SPOS02 etc. functions are identical to the

SPOS01 function.

†Note: Binary IO module has binary input circuits (BIs) and binary output circuits (BOs);

the user makes the connection between the SPOS01 function and the binary IO

module using a signal number (is made of a function ID and an "Element ID").The

signal name and number of the SPOS01 function are listed later.

Tips: If the user wishes to apply the SPOS function quickly, go to sections 4.1.4 and

4.1.5, where setting of the BI and BO circuits and the mapping of signals for IEC

61850 communication is described.

The implementation of particular features is dependent upon the selection of

hardware and the configuration of functions. Several IED models do not support certain

features. To determine whether a particular feature has been implemented within an IED,

identify the IED ordering number; and check the order number for the "G&T position" whilst

referring to the comparison table below. For more information, see

Table 4.1-1 Comparative table in respective ordering numbers
