Maximum Sync Data
For each Synchronized Data type, the system will sum the lengths in each configured group
to arrive at a total amount for that data type. The total must not exceed the size listed in the
table below:

8000
* The system flags, although included in this number, are not transferred.
Sync Networks
When using Max-ON RX3i, one or two Ethernet LANs may be configured using an
IC695ETM001 interface card to transfer the Synchronization Data. If you are using a dual
Ethernet LAN topology, then you may use two ETM001 modules in each PLC for the Sync
LANs. When the Ethernet module has been configured in the Logic Developer PLC hardware
configuration, you must assign the module a device status address. Generally, it is a good
practice to place these in the upper area of the %I reference memory. (Note: The address
must be set to %I01969 or lower.)
When dual Ethernet LANs are used, you must specify which device is to be the Primary
device and which is to be the Secondary device. The Ethernet Modules must be in the same
slot positions in each of the two RX3i main racks.
To display the configuration of the Sync Networks Interface Modules, expand the Sync
Networks node in the Project tree. Now the configurations of the two Primary Interface
modules are displayed.
