Omron FQM1-CM001 User Manual

For example, if the number of link words is set to 10, the CJ1M CPU Unit
(master) will broadcast CIO 3100 to CIO 3109 from its I/O memory and to
CIO 0080 to CIO 0089 in the I/O memory of each FQM1 Controller (slaves).
Each FQM1 Controller will send CIO 0090 to CIO 0099 from its I/O memory to
consecutive sets of 10 words in the CJ1M CPU Unit. 

The words that will be sent depend on the number of link words as shown in
the following table. 

CJ1M CPU Unit I/O memory addresses are given in parentheses.
