8. Select the type(s) of data exchange (Polled, Change of State, and /or
Cyclic). In our example, we selected Polled.
9. Type the number of bytes that are required for your I/O in the Input
Size and Output Size boxes. The size will depend on the I/O that you
enabled in the adapter. This information can be found in Parameter
16 - [DSI I/O Actual] in the adapter.
Table 4.A shows common
configuration Input/Output sizes.
In our example, we typed 4 in the Input Size and Output Size boxes
because the Mode Jumper on the adapter is set to “Single” (default)
and Parameter 16 - [DSI I/O Active] is set to “Drive 0” (only one
drive being connected). Logic Command/Reference uses 4 bytes and
Logic Status/Feedback uses 4 bytes.
