CHAPTER 5: SETTINGS PRODUCT SETUP
L90 LINE CURRENT DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 5-105
5
The configuration menu allows a maximum of four ASDUs containing measurands.
Measurands are sent as a response to Class 2 requests, which are cyclic requests coming from the master.
TYPE IDENTIFICATION (TYP) — The configuration field TYP indicates how many measurands are present in the corresponding
ASDU. Each ASDU can take either 4 or 9 measurands maximum, depending on the type identification (3 respectively 9). For
any change to take effect, restart the relay.
FUNCTION TYPE (FUN) and INFORMATION NUMBER (INF) — These two fields form the Information Object Identifier of the ASDU
as defined in IEC 60870-103. For any change to take effect, restart the relay.
SCAN TIMEOUT (SCAN TOUT) — This is the cyclic period used by the L90 to decide when a measurand ASDU is included in a
response. The measurand is sent as response to a Class 2 request when the corresponding timeout expires. The default
value 0 means 500 ms.
