CONFIGURING DATA TAGS
EDITING INTEGER TAGS
THE DATA TAB (ARRAYS)
The Data tab of an integer array contains the following properties...
• The Mapping property is used to specify if the variable is to be mapped to a
register in a remote device, or if it exists only within the Master. If you press the
arrow button and select a device name from the resulting menu, you will be
presented with a dialog box that will allow a PLC register to be selected.
• The Elements property is used to indicate how many data items the array should
hold. Array elements are referred to using square brackets, such that Array[0] is
the first element, and Array[n-1] is the last element, where n is equal to the
value entered for this property.
• The Sign Mode property is used to override the default behavior of the comms
driver when reading 16-bit values from a remote device. The driver will
normally make a decision about whether to treat these values as signed or
unsigned, based upon how the data is normally used within the device. If you
want to override this decision, set this property as required.
• The remainder of the properties are as described for the Data tab of flag tags.
THE FORMAT TAB
