M17087-3 v8
The function block Local remote (LOCREM) handles the signals coming from the
local/remote switch. The connections are seen in Figure
125, 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. The switching between
external and local HMI source is done through the parameter ControlMode. The
outputs from the LOCREM function block control the output PSTO (Permitted
Source To Operate) on Bay control (QCBAY).

Figure 125: Configuration for the local/remote handling for a local HMI with two
bays and two screen pages
If the IED contains control functions for several bays, the local/remote position can
be different for the included bays. When the local HMI is used the position of the
local/remote switch can be different depending on which single line diagram screen
page that is presented on the local HMI. The function block Local remote control
(LOCREMCTRL) controls the presentation of the LEDs for the local/remote
position to applicable bay and screen page.
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
