Gw XML setup

Element: Setup

The XML setup starts with the tag Setup. The entire setup is contained in this element.

All id attributes must be unique!

This element contains:

Element: Device
- At least one element of this type.
Attribute: device
- If more than one Device element available. This attribute specifies the id of the Device to use as current setup.

<Setup device="Telem-Gw6-1">
	<Device id="Telem-Gw6-1" />
	<Device id="Gw1" />
	<Device id="Gw2" />
</Setup>

Element: Device

This element contains setup for a specific device. This might be Gw itself or some substation device or SCADA device.

This element contains:

Element: Channel
Element: Protocol
Element: Objects
Element: Interfaces
Attribute: id
- Used for element identification

Child elements of Device when used as GW device

<Device id="Telem-Gw6-1">
	<Channel />
	<Interfaces />
</Device>

Child elements of Device when used as the device we're connecting to.

<Device id="DI-24T-1">
	<Protocol />
	<Objects />
</Device>

Element: Channel

This element contains:

Element: Port
- If more than one Port is specified, they are for redundancy.
Element: Device
Element: Objects

<Channel id="DI-24T-1">
	<Port />
	<Device />
	<Objects />
</Channel>

Element: Protocol

<Protocol comment="protocol8" id="prot_8_0">
	<Address />
	<CommunicationDelay unit="millisecond">0</CommunicationDelay>
	<PollingTimeout unit="millisecond">500</PollingTimeout>
	<TimeSync />
	<TimeoutRemoveCount>5</TimeoutRemoveCount>
	<TimeoutRemoveTime unit="second">20</TimeoutRemoveTime>
	<ReplaceTime>false</ReplaceTime>
	<GeneralInterrogationForwarding>false</GeneralInterrogationForwarding>
	<Type SubVersion="0" isMaster="false">IEC101UnBalanced</Type>
</Protocol>

Element: TimeSync

Timesync interval and correction setup

<TimeSync isEnabled="true">
	<Interval unit="second">30</Interval>
	<Correction />
</TimeSync>

Element: Correction

Possible timesync correction types:

Absolute
- Timesync message shall always be modified by this amount.
ConnectionSpeed
- Baudrate based(only when using serial port)

<Correction>
	<Absolute enabled="true" unit="millisecond">0</Absolute>
	<ConnectionSpeed enabled="true"/>
</Correction>

Element: Address

This element can refer to protocol address or some specific object address.

Address for protocol

This elements contents depend on the protocol selected

Iec-10x

<Address>
	<LinkAddress>1</LinkAddress>
	<LinkAddressLength>1</LinkAddressLength>
	<AsduAddress>1</AsduAddress>
	<AsduAddressLength>2</AsduAddressLength>
	<ObjectAddressLength>2</ObjectAddressLength>
</Address>

MODBUS

Value: integer

<Address>2</Address>

IEC62056-21

Value: string

Can be empty if only one device on channel.

<Address id="0.0.0">addr123</Address>

If this Address element contains attribute id, It shall be used for device verification.

Address of object

Iec-10x

Value: integer

<Address index="0">10</Address>

attribute index is unnecessary if value==0

IEC61580/IEC62056-21

Value: string

<Address>5.3.5</Address>

Other

Other protocols might have additional fields.

Element: Port

<Port>
       <Buffer id="inBuffer"/>
       <Buffer id="outBuffer"/>
       <IoBuffer in="inBuffer" out="outBuffer"/>
</Port>

Port data forwarding

It is possible to send data from one port to another.

To do that, port1's input buffer is the same as port2's outputbuffer and vice versa.

<Port id="port1">
       <Buffer id="portBufferIn"/>
       <Buffer id="portBufferOut"/>
       <IoBuffer in="portBufferIn" out="portBufferOut"/>
</Port>
<Port id="port2">
       <IoBuffer in="portBufferOut" out="portBufferIn"/>
</Port>

The same method allows creation of a local loopback.

<Port id="portLoopback">
       <Buffer id="portBuffer"/>
       <IoBuffer in="portBuffer" out="portBuffer"/>
</Port>

Serial port

<Port class="SerialPortSetup">
	<BaudRate>9600</BaudRate>
	<DataBits>8</DataBits>
	<StopBits>1</StopBits>
	<Parity>none</Parity>
	<FlowControl>none</FlowControl>
</Port>

TCP/IP server

<Port class="TcpIpServerSetup">
	<PortNumber>80</PortNumber>
	<ClientIpMask>0.0.0.0</ClientIpMask>
	<Interface>eth0</Interface>
</Port>

Element: ClientIpMask

Defines who is allowed to connect with us. More than one possible.

TCP/IP client

<Port class="TcpIpClientSetup" name="16">
	<PortNumber>502</PortNumber>
	<IpAddress>10.0.0.89</IpAddress>
	<Interface>eth0</Interface>
</Port>

Virtual port

They are ports 3-5 on GW6.

<Port class="VirtualPortSetup">
	<Port class="SerialPortSetup">
	      <BaudRate>9600</BaudRate>
	      <DataBits>8</DataBits>
	      <StopBits>1</StopBits>
	      <Parity>none</Parity>
	      <FlowControl>none</FlowControl>
	</Port>
</Port>

Element: Objects

Element: Object

Depending on protocol the object belongs to (master/slave), has different child elements.

Possible child elements:

Address
Buffer
Filter
MxValue

Attribute: type

Defines object type.

Possible values:

DI
AI
CN
DO
AO

Element: MxValue

Defines the object for current/latest value.

Child elements define default value, flags and time tag.

<MxValue id="DI_6_value">
	<Value>0</Value>
	<BitMask>
		<Bit>Invalid</Bit>
		<Bit>NotTopical</Bit>
	</BitMask>
</MxValue>

Element: Filter

Defines what is going to happen to the incoming measured value.

Filters can be daisy chained. To achieve different outcomes.

When an event is received, it is sent to it's filter. After the filter does what it's supposed to do, it will pass the event to the Next Filter

<Filter class="Change">
	<Filter class="Proxy" />
</Filter>

AddToBuffer

AddToBuffer may have more than one Target.

Target is a Buffer object.

<Filter class="AddToBuffer">
	<Target ref="DI_0_7_buf"/>
	<Target ref="DI_1_7_buf"/>
	<Target ref="DI_2_7_buf"/>
	<Target ref="DI_3_7_buf"/>
	<Target ref="DI_4_7_buf"/>
</Filter>

Assert

Passes event to the next filter only if specified target(MxValue) == false.

<Filter class="Assert">
	<Target ref="DI_7_value"/>
</Filter>

Change

Detects change in Digital measurments value and status bits.

Deadband

Used to detect change in analog and counter values

<Filter class="Deadband">
        <Type>X</Type>
        <Threshold>2</Threshold>
</Filter>

Integral

New deadband type, not implemented.

Absolute

This deadband is used for counter values.

f=abs(new_value-old_value)>Threshold

Deadband1

This deadband is used for analog values.

Fallback

Falls back to specified value.

Normalize

This filter is used for converting floating point value to normalized value.

This filter works only on floating point values. Normalized values shall be passed on without change

<Filter class="Normalize">
	<To>-1...1</To>
	<Max>100</Max>
	<Min>10</Min>
</Filter>

Element To has two possible value: -1...1 or 0...1 and this selects the formula and overflow conditions being used.

Range -1...1

normalized_value=float_value/Max

overflow is set when normalized_value < -1 && normalized_value > 1

No element Min for this range

Range 0...1

normalized_value=(float_value-Min)/(Max-Min)

overflow is set when normalized_value < 0 && normalized_value > 1

Inversion

Inverts the passed digital value.

Proxy

Proxy may have more than one next Filter.

<Filter class="Proxy">
	<Filter class="AddToBuffer" />
	<Filter class="AddToBuffer" />
	<Filter class="Fallback" />
</Filter>

Scale

This filter works only on normalized values. Non-normalized(floating point) values shall be passed on without change

scaled_value=normalized_value*(Max-Min)+Min

<Filter class="Scale">
	<Max>100</Max>
	<Min>10</Min>
</Filter>

If element Min=0 then no need to define that element, value 0 is used as default for Min. Element Max must always exist. Element To is not used.

UpdateValue

Target is a MxValue object.

<Filter class="UpdateValue">
	<Target ref="DI_7_value"/>
</Filter>

Element: Buffer

Defines a buffer object, with depth.

<Buffer id="DI_8_0_buf">
	<Depth>10</Depth>
</Buffer>

Element: Formula

Possible child elements:

Buffer
MxValue

     <Buffer id="DI_f0_0_0_buf">
         <Depth>10</Depth>
     </Buffer>
     <Buffer id="DI_f0_0_1_buf">
         <Depth>10</Depth>
     </Buffer>
     <Filter class="Formula">
         <O>or<O/>
         <a>DI_f0_0_0_buf<a/>
         <a>DI_f0_0_1_buf<a/>
         <Filter class="Change">
             <Filter class="UpdateValue">
                 <Target ref="DI_f0_value"/>
                 <Filter class="AddToBuffer" />
             </Filter>
         </Filter>
     </Filter>
 </Formula>
