N-File Description
N40 This N-file lets you use Emulated Block Transfer messages to read and write
many types of DPI 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.
