Local/Remote switch

Introduction

The signals from the local HMI or from an external local/remote switch are applied
via function blocks LOCREM and LOCREMCTRL to the Bay control (QCBAY)
function block. A parameter in function block LOCREM is set to choose if the
switch signals are coming from the local HMI or from an external hardware switch
connected via binary inputs.

Principle of operation

The function block Local remote (LOCREM) handles the signals coming from the
local/remote switch. The connections are seen in figure 167, where the inputs on
function block LOCREM are connected to binary inputs if an external switch is
