How to Use the Node Terminal Block
Appendix 2
227
Block addresses 501 and 502 are each sent (allocated) to the Area to send to computer of the Data Memory
area for the node terminals.
When the leading address (S) of the Data Memory area for the Node Terminals is taken to be D16020 (set to
ITEM043):

In this example, let’s assume that the PC is node 01 and that the computer on which CX-Process Monitor is
running is node 02.
Each of the data link tables is set as follows:
Node: 01, Link start word: D16020
