The DPSY01 function can issue a "Result" signal at the output point "DPSY01_SLD_CSCN".
Operate condition for the counter
(iii)
Figure 4.1-36 illustrates the operate condition logic. The DPSY01 function can determine an
operate-condition using a signal received from "Control hierarchy". The Control hierarchy
condition is provided by user-programmed PLC logic (i.e., 43R/L); the user must connect the
control-hierarchy with the DPSY01 function using connection point "DPSY01IN_TMP_47" (see
Table 4.1-25).

Note: "Command Blocking" disables all operation except for its own; the "Command
1
Blocking" function is initiated by the status of "CBK" in a software switch
controller (SOTFSW). The IEC 61850 standard defines the "Command Blocking"
function as "CmdBlk". For more information on "CBK", see Chapter
monitoring application: Software switch controller. See the signal
"
"S4301_STATE" of Table 4.1-6.
Note: "Double Command Blocking" (DCB) is an operation philosophy. It can be used to
2
protect the substation. The user can program it using GR-TIEMS. The DCB
operating signal is denoted as "DCB RCV OR) in Table 4.1-6.
Note: If the event "device-travelling" is detected, it indicates that another operator is
3
changing the status of a device. Thus, the IED should inhibit the operation of any
device for the duration that the event is detected. The detecting signal is denoted
as "Travelling OR" in Table 4.1-6.
Note: If the issue of a trip command is executed by the IED, any control operation is
4
blocked until the trip operation is completed. If an IED includes a relay
application, the trip command is issued at the output-point "GEN.TRIP" in Table
4.1-6.
