which is operated from the local HMI, the output BLKINFO on the IEC command function block
ICOM has to be connected to an input on an event function block. This input must have the
information number 20 (monitor direction blocked) according to the standard.
Disturbance Recordings
For each input of the Disturbance recorder function there is a setting for the information number
of the connected signal. The function type and the information number can be set to any value
between 0 and 255. To get INF and FUN for the recorded binary signals, there are parameters on
the disturbance recorder for each input. The user must set these parameters to whatever he
connects to the corresponding input.
Refer to description of Main Function type set on the local HMI.
Recorded analog channels are sent with ASDU26 and ASDU31. One information element in these
ASDUs is called ACC, and it indicates the actual channel to be processed. The channels on
disturbance recorder are sent with an ACC as shown in Table 69.
