network, is easily accessible on a single tool program. For more information, refer to
the operator's manual.
Activate LON Communication
Activate LON communication in the Parameter Setting tool under Main menu/
Communication/ SLM configuration/ Rear optical LON port/ Horizontal
communication, where Operation must be set to ON.
Add LON Device Types LNT
A new device is added to LON Network Tool from the Device menu or by installing
the device from the ABB LON Device Types package for LNT 505, with the SLDT
670 series package version 1p2 r03.
LON net address
To establish a LON connection with the 670 series IEDs, the IED has to be given a
unique net address. The net address consists of a subnet and node number. This is
accomplished with the LON Network Tool by creating one device for each IED.
Vertical communication
Vertical communication describes communication between the monitoring devices and
protection and control IEDs. This communication includes sending of changed process
data to monitoring devices as events and transfer of commands, parameter data and
disturbance recorder files. This communication is implemented using explicit messages.
Events and indications
Events sent to the monitoring devices are using explicit messages (message code 44H)
with unacknowledged transport service of the LonTalk protocol. When a signal is
changed in the IED, one message with the value, quality and time is transmitted from
terminal.
Binary events
Binary events are generated in event function blocks EVENT:1 to EVENT:20 in the
670 series IEDs. The event function blocks have predefined LON addresses. table
shows the LON addresses to the first input on the event function blocks. The addresses
to the other inputs on the event function block are consecutive after the first input. For
example, input 15 on event block EVENT:17 has the address 1280 + 14 (15-1) = 1294.
For double indications only the first eight inputs 1–8 must be used. Inputs 9–16 can be
used for other type of events at the same event block.
As basic, three event function blocks EVENT:1 to EVENT:3 running with a fast loop
time (3 ms) is available in the 670 series IEDs. The remaining event function blocks
EVENT:4 to EVENT:9 runs with a loop time on 8 ms and EVENT:10 to EVENT:20
runs with a loop time on 100 ms. The event blocks are used to send binary signals,
integers, real time values like analogue data from measuring functions and mA input
modules as well as pulse counter signals.
