Binary events are generated in Event function blocks EVENT:1 to EVENT:20 in
the IEDs. The EVENT function blocks have predefined LON addresses. Table
shows the LON addresses to the first input on the EVENT function blocks.
Addresses to the other inputs on the EVENT function block are consecutive after
the first input. For example, input 15 on EVENT:17 function block 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 types of events at the same EVENT block.
Three EVENT function blocks EVENT:1 to EVENT:3 running with a fast loop
time (3 ms) are available as basic in the IEDs.. The remaining EVENT function
blocks EVENT:4 to EVENT:9 run with a loop time of 8 ms and EVENT:10 to
EVENT:20 run with a loop time of 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 PCFCNT:1 to PCFCNT:16 are available in
the IEDs.
The first LON address in every EVENT function block is found in table 491. The
formula for calculating the LON address is:
LON Address = (EVBlkNr-1)×16 + signalNr +1023
For instance, the first pin at Event block number 2 has the address: (2-1)×16 +1
+1023 = 1040
