N-File
Description
N40
This N-file lets you use Emulated Block Transfer to send many types of
messages. To use Emulated Block Transfer messages, you send a Write
message to N40:0 – N40:63, wait until the adapter responds with a reply
message, and then read the response data in N40:0 – N40:63 with a Read
message.
For details about Block Transfer messages and the data required for each
byte in the N-File, refer to the Remote I/O Adapter User Manual, Publication
20COMM-UM004….
Bits 15 to 8 are the Most Significant Byte. Bits 7 to 0 are the Least Significant
Byte.
