f. For the Input Size and Output Size boxes, use the pull-down menus

to choose the number of bytes that are required for your I/O.

The size will depend on the drive’s Reference/Feedback and the

number of Datalinks used in your I/O (enabled with adapter

Parameter 13 - [DPI I/O Cfg]), and the selected data exchange

method. (A 16-bit word is two bytes, and a 32-bit word is four

bytes.) For this example, an Input Size of ‘20’ and an Output Size

of ‘20’ are used.

Important:Make sure that the bits for Parameters 25 - [M-S

Input] and 26 - [M-S Output] are set to match

Parameter 13 - [DPI I/O Cfg]. See Setting a

Master-Slave Hierarchy (Scanner-to-Drive

Communication) on page 3-5 for details.

Table 4.E

, Table 4.F, or Table 4.G list the number of bytes required

for the Input Size and Output Size boxes for specific I/O

configurations—and only the Polled data exchange method. For

Input Sizes and Output Sizes for other data exchange methods and

specific I/O configurations, see the tables in Appendix
