Module Configuration

Chapter 4

4-7

Important: Scaling values must always be entered in BCD format,

even if the data format chosen is binary. If scaling is selected for any

channel, all channels must be scaled. If scaling is not required on certain

channels, set those to the default input range: 0 to 4095 for 0 to + voltage

or current ranges, and -4095 to +4095 for - to + voltage or current ranges.

If scaling is not selected, the module requires specific minimum BTR

file lengths for the number of channels used. The BTW file length can

be set to 3 words. Table 4.F shows the required BTW and BTR file lengths.
