Dave Posted August 7, 2017 Report Share Posted August 7, 2017 I have a project configured with 9 EX-RC1's and a Unistream USP-156-B10......I just discovered in the help files that there is a limit of 8 EX-RC1's in one project. The Unilogic software allowed me to set-up all 9 EX-RC1's without any warnings. The actual hardware is in the process of being installed and wired. Can anyone tell me if this configuration is going to cause a problem? There are a total of 14 digital I/O modules connected to the EX-RC1's, with the largest number of I/O modules on any one adapter being 3. I am hoping that the help file is outdated and that I can actually have more than 8 adapters in my project. I wont be able to actually test it until installation is complete, and would really like to know before then. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted August 7, 2017 MVP 2021 Report Share Posted August 7, 2017 Worst case you could program one of the RC1's to read another RC1 and then read all the data from the "sub-master". Yes, I know this a hack. Hopefully you can do it all from the UniStream. But I don't know. Joe T. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Ausman Posted August 8, 2017 MVP 2021 Report Share Posted August 8, 2017 On top of Joe's idea, another suggestion: Can you run longer cabling b/n the closest pair of RC1s to reduce your total to 8? You're not loading them up much, so perhaps this might be the simple solution needed. As they're only digital I/Os this should be easily achieved with multicore shielded, even for a relatively long distance, given that you must already have cable runs b/n them somewhere and if already exposed then conduits already exist. Phew...that was a long sentence! And it also lets you do it now during construction, rather than stuff around later. cheers, Aus Quote Link to comment Share on other sites More sharing options...
Dave Posted August 9, 2017 Author Report Share Posted August 9, 2017 Interesting idea about the "sub-master" RC1 Joe. I don't think that would have ever occurred to me. I had already been thinking about the cable b/n two adapters and wasn't really liking that option I don't really see any reason why it wouldn't work perfectly well with more than 8 adapters.......in Unilogic, there are two 32 bit registers (UniCan Stasticics Struct.Alive Bitmap) that act as a bitmap to display which Canbus ID#'s are "alive". That leads me to believe that there are closer to 60 max. units allowed (Vision series can handle up to 60 nodes on the UniCan network) I had five of nine units connected and functioning today and I will have the last 4 connected for testing tomorrow. Thanks for the contingency plans. Hopefully won't need them. dave Quote Link to comment Share on other sites More sharing options...
DanT Posted August 9, 2017 Report Share Posted August 9, 2017 Got the answer from Unitroncis Up to 16 EX-RC1's can be used with a UniStream PLC+HMI Quote Link to comment Share on other sites More sharing options...
