Chapter 5: DSM314 to Host Controller
Interface
This chapter defines the data that is transferred between the CPU and the Motion Mate
DSM314 automatically each host controller sweep, without user programming. This data is
categorized as follows:
•
Input Status Data (Transferred from Motion Mate DSM314 to CPU)
— Status Bits: 32 (1 Axis), 48 (2 Axes),64 (3 Axes), 80 (4 Axes) bits of %I data
— Status Words: 24(1 Axis),44 (2 Axes) ,64 (3 Axes) ,84 (4 Axes) words of % AI
data
•
Output Command Data (Transferred from CPU to Motion Mate DSM314)
— Discrete Commands: 32(1 Axis),48(2 Axes),64(3 Axes),80(4 Axes) bits of %Q
data
— Immediate Commands: 3(1 Axis),6(2 Axes),9(3 Axes),12 (4 Axes) words of %AQ
data
Note: Throughout this chapter words shown in italics refer to actual host controller machine data
references (%I, %A, %AI, %AQ).
5.1 Section 1: %I Status Bits
The following %I Status Bits are transferred automatically from the DSM314 to the CPU each
sweep. The actual addresses of the Status Bits depend on the starting address configured
for the %I reference (see Table 40, “Settings Tab”). The bit offsets listed in the following table
are offsets to this starting address. All reference section designations pertain to this chapter.
