7.11 Number of Input/Output Bytes

7.11.1 Factors determining the number of input/output bytes

The number of input/output bytes for the D.Station is determined by the following factors:
• Number of mount base slots
• Number-of-points settings for each D.Station slot (SLOT rotary switch setting)
• I/O error information/Implementation information additional setting for the D.Station
(FUNC1 rotary switch setting)
• Selection of the FIX/FREE options for the D.Station (FUNC2 rotary switch setting)
As indicated in Table 7-10, the number of input/output bytes varies with the number of
mount base slots, number-of-points setting, selection of the FIX/FREE option, and
additional error information setting.
