Basler Electric BE1-851E DNP3 Protocol - Manual (Page 26)

Appendix for Binary Output Status Points and Control Relay Output
Blocks
To enable Master which can support only Trip and Close commands to control BE1-851E Control Relay
Output Block points, second way of controlling Control Relay Output Blocks is added as presented in
Table 5-3.
User can select old (legacy) Control Relay Output Blocks (Table 5-2) or a new (Table 5-3) via DNP object
41 point 24. Selection stays remembered in non-volatile memory. When Table 5-2 is selected, object 40,
point 24 has value 1. When Table 5-3 is selected, object 40, point 24 has value 2. When selecting specific
Control Relay Output Blocks table, object 41, point 24 must be set to 1 or 2 via function codes
select/operate or only direct operate or direct operate, noack.
Notes:
- Old Control Relay Output Blocks (Table 5-2) has 27 points while new Control Relay Output
Blocks (Table 5-3) has 38. The additional 11 points are added as single function points to support
only pulsing control. New Control Relay Output Blocks (Table 5-3) has only complementary or
single function indices and is DNP compliant.
- Reading values of points 0 to 27 are the same in the both Control Relay Output Blocks tables.
Reading values of points 28 to 40 in the new Control Relay Output Blocks (Table 5-3) are the
same as for points 0 to 8, and points 37 to 40 have the same reading values as points 18 to 21.
