HI All, I was hoping someone may be able to share some tips polling a number of Compact Logix PLC via ethernet radio (4RF Aprisa SR+). Refresh cycle would be fine if under 5-10s.
Some colleagues have said that the Radios do not handle the ABCLX driver traffic. In the past, another PLC was installed at the base station radio that would poll the Other stations via CIP Read commands, Citect would then poll this PLC over the local copper network. (This obviously adds an additional point of failure).
Are there any parameters I can play with/alternative drivers I could investigate before I set it up on the bench?
- I have my eye on device specific parameters (Scan Rate, delay, maxpending), as the stations don't require near real time refresh rates. (Wastewater Pumping Stations)

ScanRate=5000 - Adjust System Overhead Time Slice in the PLC to the highest value possible.
Cheers!
