            Description

            ECS LFW uses by default the ControlByte values for SM2 and SM3 as follows in order to support IRQ based control: 

            <Sm MinSize="0" MaxSize="1024" StartAddress="#x1100" ControlByte="#x64" Enable="1">Outputs</Sm>
            <Sm MinSize="0" MaxSize="1024" StartAddress="#x1D00" ControlByte="#x20" Enable="1">Inputs</Sm>

            In order to support migration of replacement devices which used different ControlByte value, e.g. allow ControlByte.EnableIrq to be 0 for SM2 and SM3:

            <Sm StartAddress="#x1000" ControlByte="#x64" Enable="1">Outputs</Sm>
            <Sm StartAddress="#x1600" ControlByte="#x00" Enable="1">Inputs</Sm>

            the firmware supports configuration of the ControlByte Mask by using ECS_SET_CONFIG_EXT_REQ message after regular SET_CONFIG_REQ configuration.
