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 384 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.
16 pulse counter value function blocks PCGGIO:1 to PCGGIO:16 and 24 mA input
service values function blocks SMMI1_In1 to 6 – SMMI4_In1 to 6 are available in
the 670 series IEDs.
