Network Communications 3-10

3 Word I/Os Message

The 3 word I/Os, combined input/output, messages have only one fixed area. This is the most frequently used data and is referred to as the

fast I/O data. 3 Word messages are used when processor memory is a critical factor in the network design. As shown below, the 3 word I/Os

message contains only the minimum drive data.

# Fast I/O Output Data

The fast I/O output data area is used to transfer parameter data directly to the drive via a dual port RAM interface. The following table

details the functions of the fast I/O output data (Bytes 0 to 5) For detailed explanation of the terminal and multi-function inputs and outputs,

refer to the appropriate drive technical manual.
