12.3.5 Local/Remote switch LOCREM, LOCREMCTRL
12.3.5.1 Introduction
The signals from the local HMI or from an external local/remote switch are applied via
the 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.
12.3.5.2 Principle of operation
The function block Local remote (LOCREM) handles the signals coming from the local/
remote switch. The connections are seen in figure
328 , 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).
