Technical manual
The switching of the Local/Remote switch requires at least system operator level. The
password will be requested at an attempt to operate if authority levels have been defined
in the IED. Otherwise the default authority level, SuperUser, can handle the control
without LogOn. The users and passwords are defined in PCM600.

Local remote/Local remote control LOCREM/LOCREMCTRL

The function block Local remote (LOCREM) handles the signals coming from the local/
remote switch. The connections are seen in figure 178, where the inputs on function block
LOCREM are connected to binary inputs if an external switch is used. When the local
HMI is used, the inputs are not used and are set to FALSE in the configuration. The outputs
from the LOCREM function block control the output PSTO (Permitted Source To
Operate) on Bay control (QCBAY).
