Data Formats
The data selected for a controller address must reflect the same format as the
data actually stored in that address. This is the only way you can ensure that
correct, consistent information is displayed.
For example, selecting 16 Bit Signed Integer format for address N7:10
displays data one way and selecting 16 Bit BCD format for the same address
displays data another way. It is important to understand each data format and
its characteristics.
The following table illustrates all data formats supported by PLC and SLC
controllers including the point types and ranges applicable to each format,
and whether the scaling may be used.
Data Format PLC Register Range Scaling User Input Range
Bit 0,1 No 0, 1, Y, N
16 Bit Signed Integer -32,768 to +32,767 Yes -32,768 to +32,767
16 Bit Unsigned Integer 0 to +65,535 Yes -32,768 to +32,767
16 Bit BCD 0 to 9999 Yes

➀ 16 Bit BCD is 0-9999 on an SLC, but data can be scaled to -32,768 to +32, 768.
➁ Not available on SLC controllers.
