Signal flow between apparatus control function blocks
Remote/Local switch
The IED has Remote/Local (R/L) switch available on the LHMI. However, if it is
required to use R/L switch externally, that is, to use switch other than available on
LHMI, it is necessary to use Local remote (LOCREM) function in the configurations.
LOCREM function has the three following binary inputs - CTRLOFF, LOCCTRL
and REMCTRL. The information from the external switch needs to be connected to
LOCREM function via binary inputs.
Consider the example as shown in
from the external R/L switch is connected to binary input card. These binary inputs are
then connected to LOCREM function in Application Configuration Tool (ACT). It is
also required that the setting Control mode of LOCREM function is set to External
LR-switch switch.
