Station communication

1) * User defined information value (PARAM.3)

2) * User defined information value (PARAM.2)

3) 9 = Measurands II, Format = Measurand II (7.3.1.8 in IEC 60870-5-103:1997), semantics per IE is defined by

semantics of connected source.

<Number of information elements> is defined by index of first input not connected.

Example: Input1, Input2, and Input4 are connected, Input3 is not connected.

<Number of information elements> will be 3 (Input3 NOT connected) -1 = 2, that is, only Input1 and

Input2 will be transmitted.

Disturbance recordings

The following elements are used in the ASDUs (Application Service Data Units) defined in the

Analog signals, 40-channels: the channel number for each channel has to be specified. Channels

used in the public range are 1 to 8 and with:

connected to channel 1 on disturbance function block A1RADR

connected to channel 2 on disturbance function block A1RADR

connected to channel 3 on disturbance function block A1RADR

connected to channel 4 on disturbance function block A1RADR

Channel number used for the remaining 32 analog signals are numbers in the private range 64 to

Binary signals, 96-channels: for each channel the user can specify a FUNCTION TYPE and an

INFORMATION NUMBER.

Disturbance upload

All analog and binary signals that are recorded with disturbance recorder can be reported to the

master. The last eight disturbances that are recorded are available for transfer to the master. A

connected to channel 5 on disturbance function block A1RADR

connected to channel 6 on disturbance function block A1RADR

connected to channel 7 on disturbance function block A1RADR

connected to channel 8 on disturbance function block A1RADR
