Code Description

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.

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.

3.4.4 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.

3.4.5 Poll Interval

0 to 65535

This parameter specifies the minimum interval to execute continuous commands

(Enable code of 1). The parameter is entered in units of seconds. Therefore, if a

value of 10 is entered for a command, the command will execute no more

frequently than every 10 seconds.

3.4.6 FP Word Count

-1 to 125

This parameter specifies the number of words from the floating point data

returned by a HART command that will be placed on the Virtual Database. If this

parameter is 0 no data will be written to the Database. If this parameter is -1 then

all the floating point data will be written in the integer block of data.

Special care should be taken with this number, because is a word count and a

floating point value is 2 words long. For example if you execute a HART

command 3 which takes 5 floating point values from the device, you should place

a word count of 10 words.

3.4.7 Swap Code

0, 1, 2, 3

This parameter defines the byte order of each four-byte group of data received.

This parameter is helpful when dealing with floating-point or other multi-register

values, as there is no standard byte order for storing these data types. The

following table describes the values and their associated operations:
