4.8.2 Slave to Master Data Composition (PC Controller Case)
The answer data coming from the N568B/LC are automatically stored into the HS CAENET controller
Receive Data buffer and therefore are available to the User.
The following Table shows the structure of the N568B/LC data packet:

4.9 MASTER TO SLAVE OPERATING CODES (PC CONTROLLER
CASE)
The MASTER-to-SLAVE Operating Codes of the module N568B/LC have the following structure:
-
Byte 1: %01 (Low Byte Controller identified code);
-
Byte 2: %00 (High Byte Controller identified code);
-
Byte 3: %XX (Low Byte Module Number);
-
Byte 4: %00;
-
Byte 5 ÷ 8: see Table 4.17
