Parameter Reading

Read

Use PLC Tags or Block Tags to read parameters from a given infusion pump. Use as many Tags as needed to read parameters, and there must be one Tag per parameter. This Tag returns a reading error if the selected parameter does not have the same name used by the device when communicating.

Syntactic and size parameters

Device

Address of an infusion pump

Item

Parameter's name

Size

2 (two) if it is a Block Tag

 

If users want to omit the Device field, the expected syntax for the Item field is the following:

<Infusion pump address>:<Parameter's name>

 

Using a Block Tag

 

Block Element

Value

Element 1

Time since a SpaceCom device was turned on, in seconds

Element 2

Parameter's value. The data type of this value depends on which parameter it refers to

 

Using a PLC Tag

The PLC Tag's Value property contains the value of the parameter, and its data type depends on which parameter it refers to. Compared to a Block Tag, it is the same content as Element 2.

 

Data Types of Values

Data types of values, depending on which parameters they refer to, can be DWord, Double, Date, or String.

 

NOTES

The TIME parameter contain a value in DWord format corresponding to the number of seconds elapsed in a day.

The DATE and DLCRETIME parameters contain their respective values in Date format.

A device can provide a parameter without a value. In this case, the Value property of a PLC Tag or the Element 2 of a Block Tag display an empty value.
