PART 2: CX-Server PLC Tools
CHAPTER 10 – Data Links
Data Link Setup Example
The refresh sequence for nodes 1 and 2 is as follows: #1, #2, #3. For node 3, the order is #2, #1, #3. Node address
03 does not receive all of the data sent from node address 02. Rather, data from the 20 words (CIO 1240 to CIO
1259) beginning from the start address +10 words (i.e., the offset) is received in IR 300 to IR 319. Other data is
received with no offset.
