Enable
0, 1, 2, 3, 4, 5
This field defines whether the command is to be executed and under what
conditions.
Code Description
0 The command is disabled and will not be executed in the normal polling
sequence. This can be used to process a command from a bursting slave
device.
1 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.
2 The command will execute only if the internal data associated with the command
changes. This value is valid only when there is a specified "Write DB Address"
(see below) with a non zero byte count for write commands.
3 The HART module will send the command if either the MVI69-HART module OR
the HART device is powered up. This is mainly used for configuration of HART
devices on startup.
4 Places the command in enabled mode. This option is valid only if there is a
specified "Enabled DB Address" (see below). If the Virtual Database word
specified in "Enabled DB Address" has "-1" the command will be executed
otherwise it will not.
5 Places the command in one shot enabled mode. This option is valid only if there
is a specified "Enabled DB Address" (see below). If the Virtual Database word
specified in "Enabled DB Address" has a value of "-1" the command will be
executed otherwise it will not. When the command has been successful the
Virtual Database word specified in "Enabled DB Address" will be written with "0",
so the command will be executed only once.
Refer to Command Enable Control Block (9902) (page 92) and Command
Disable Control Block (9903) (page 92) for more information on how to use the
enable code.
Float DB Address
0 to 3998
This field specifies the internal database register where the floating point values
returned by the command will be placed.
Poll Interval
0
TO 65535
This parameter specifies the minimum interval between executions of a
continuous commands (Enable code of 1). The value is in seconds. Therefore, if
a value of 10 is entered, the command will execute no more frequently than once
every 10 seconds.
