Output signal to monitoring
The SOFTSW1 function shown in Figure 4.3-11, can issue a "Select success" signal at the
output point "S4301_FSD_CSF".
Note: The output point "S4301_FSD_CSF" is the same as the signal shown in Figure
4.3-7.

Figure 4.3-12 shows the select condition logic of the SOFTSW1 function. The SOFTSW1
function can examine an operate-condition using "Command Blocking" signal
Command blocking*1 defined as "CBK")
Double Command Blocking detected*2

Tripping *4 ("General trip")

Note: "Command Blocking" disables any operation except its own; see the signal
1
"CBK_STATE (Table 4.3-2)" as the state of "Command Blocking" in the SOFTSW
function.
Note: "Double Command Blocking (DCB_RCV_OR in Table 4.3-8)" is an operation
2
philosophy. It can be used to protect a substation. The user can configure it using
GR-TIEMS.
Note: If the event "device-travelling (Traveling OR in Table 4.3-8)" is detected in the
3
IED, it indicated that another operator is changing the status of a device. Thus,
the IED should inhibit the operation of any device for the duration that the event
is detected.
Note: If tripping (GEN.TRIP in Table 4.3-8) is executed in the IED, any control
4
operation is blocked upon the trip operation. Tripping can be introduced by the
protection function if the IED has protection functions.
