In addition there is a setting on each event block for function type. Refer to description
of the Main Function type set on the local HMI.
Commands
M17109-138 v2
As for the commands defined in the protocol there is a dedicated function block with
eight output signals. Use PCM600 to configure these signals. T
o realize the
BlockOfInformation command, 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
M17109-141 v8
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
76.
