After adding a new Data Point, the following should be configured:
Description
Data Point Type (Input, Output, None)
Data Type
Byte Length
Figure 3.60
– Configuring Data Points
After updating the Data Type, the Byte Length will be set to match the selected Data
Type. By modifying the Byte Length thereafter, an array of that Data Type can be
configured. It is however important that the Byte Length is always a multiple of the
base Data Length.
Data Type
Byte Length MUST be a multiple of:
BOOL
1
SINT
1
INT
2
DINT
4
REAL
4
Table 3.14
– Data Type – Byte Length Restrictions
IMPORTANT: It is critical that the configured Byte Length be a multiple of the base Data Type.
IMPORTANT: It is critical that the total sum of input and output bytes (of all the Data Points) match that
required by the slave device. Not adhering to this could cause unexpected results.
NOTE: The DP (Byte) Offset for each the Data Point will be automatically calculated.
