8. Enter a Requested Packet Interval (RPI) between 2.0 and 3200.0 ms in steps of
1.0 ms. The RMC ignores fractions of a millisecond and cannot support an RPI below
2.0 ms. A commonly used RPI is 20.0 ms. Very low RPIs may flood the network.
9. Make sure to check Use Unicast Connection over EtherNet/IP. This option is very
important for reducing network bandwidth required, but is available only in RSLogix
version 18.00.00 and newer.
10. Clear the Inhibit Module check box and set the Major Fault On Controller if
Connection Fails While in Run Mode check box as required by your application.
11. Click Finish.
The above steps will allocate three tags in the Controller Tags database in RSLogix 5000.
These tags correspond to the Input, Output, and Configuration data set up for the module
under the Connection Parameters section above. The type of each tag is a special
module-defined type created by RSLogix. Each special type has a Data field that holds the
actual data. The following table summarizes the tags created for each module:
Tag Name
Type Of
Data Description
[Name]:I REAL[size] This is the Input Data, where the Outgoing Cyclic I/O Data
from the Indirect Data in the RMC will appear.
If you selected to use a Sync Register, the first item in this
array is the SyncIn Register, followed by the Indirect
Data[0], Indirect Data[1], and so on:
