Item reference
An item is a named data structure accessed using any data access technology supported by the
FactoryTalk Batch
Server like the custom COM interface GetItem
method or through OPC.
TIP:
Some data returned with a request are localized. States and modes, as well as most information in the event journal are localized, based upon the language selected in the Control Panel. Time and date formats are based upon the system’s International settings.
The formatting methods used for each of the items:
Item | Description | ||
|---|---|---|---|
Input Format | Describes the COM/DCOM method used to obtain this item (REQUEST).
Use this format: object . GetItem ItemName.
For example: object.GetItem(BatchList) . | ||
Output Format | Describes the data returned and the format displayed. All data returns in CFTEXT format, representing either strings or integers. A list of the key characters and what they symbolize follows: | ||
