Parameters for CROB Control Block

The Parameters for configuring the CROB Control Block are:
Table 33:
Parameter
mComreq_Setup[20]
mComreq_Setup[21]
mComreq_Setup[22]
Refer to Section 6.3.5, DNP3 Output Block Parameters – CROBs (Section c) for CROB
configuration and mComreq_Setup[51] for defining the CROB Control word memory type.
Example COMMREQ Configuration for CROB Control
The example presented here shows the configuring COMMREQ required and the
corresponding effect on memory usage for the CROB Control Dword:
// == == == == == == == == == == == == == == == ==
// Section c. -- DNP3 Output Block Definition Parameters
// == == == == == == == == == == == == == == == ==
mComreq_Setup[50] := 76;
mComreq_Setup[51] := 8;
mComreq_Setup[52] := 6001; // Memory address for CROB objects
mComreq_Setup[53] := 0;
mComreq_Setup[54] := 16;
mComreq_Setup[55] := 0;
// == == == == == == == == == == == == == == == ==========
// DNP3 CROB Control Block Definition Parameters
// == == == == == == == == == == == == == == == ===========
mComreq_Setup[20] := 200; // Starting Memory Address of CROB Control Dword
Configuration of DNP3 outstation Parameters
This is the number of times the Outstation shall execute the operation. Counts
greater than 1 generate a series of pulses or repeated operations for the point.
This is the duration for the pulse ON time /OFF time expressed as the number of
milliseconds, that the output remains active. The pulse time can be set in 1 ms
increments up to 65 secs.
Value
0
0
0
// Memory type for CROB objects (76=%M)
// Memory type for CROB Control Dword (8=%R)
// Reserved
// Number of CROB objects
// Reserved
Description
Starting Memory Address of CROB Control Dword
No of PLC Controlled CROBs (This should be Less than what is
configured in mComreq_Setup [54])
Offset of CROB to be associated with CROB Control Dword
(starting from 1). This should be within the range provided for
CROB objects. The offset should start with 0.
