Enable Code
0 = Disabled
1 = Enabled with Poll Interval (seconds) utilized
2 = Conditional (executed when point in database changes)
This field defines whether or not the command is to be executed and under what
conditions. If the parameter is set to 0, the command is disabled and will not be
executed in the normal polling sequence. The command can be executed under
the control of the PLC processor through the use of a Command Control block.
Setting the parameter to a value of 1 for the command causes the command to
be executed each scan of the command list if the Poll Interval Time is set to zero.
If the Poll Interval time is set, the command will be executed, when the interval
timer expires. If the parameter is set to 2, the command will execute only if the
internal data associated with the command changes. This value is valid only for
write commands.
Database Index
Database Index is the location in the module's database to use as the source for
the data in the command. The data type (page 77) field determines the meaning
of the index.
Poll Interval
This parameter specifies the minimum frequency at which the module should
execute the command. The value is entered in units of seconds. For example, to
execute a command every 10 seconds, enter a value of 10 in the field. A value of
0 for the parameter implies that the command should be executed every scan of
the list.
Session Index
Session Index represents the session index in the module to associate with the
command. This index is set when the session is read in from this file. The range
of values for this field is 0 to 31.
Sector Index
Sector Index represents the sector index for the specific session. The range of
values for this field is 0 to 4.
Data Type
Data type file represents the ASDU type as follows:
Type Description DB Index type
45 Single point command Bit address
46 Double point command Bit address
47 Regulating Step point command Byte address
48 Setpoint, normalized point command Word address
49 Setpoint, scaled point command Word address
50 Setpoint, short float point command Double-word address
51 Bitstring (32-bits) point command Double-word address
