Posted 26 Apr 2016 Hi! I try to add in the I/O Configuration, the ControlNet Module 1756-CN2/C, but I can't find for Module Discovery. Why the Module Discovery show me only 1756-CN2/A and 1756-CN2/B? Where I find 1756-CN2/C? I have all versions of RSlogix5000 10 to 20. Thanks for the attention. Share this post Link to post Share on other sites
Posted 27 Apr 2016 If you are trying to discover a module and Logix will not give you the latest revision of that module, then either (a) Logix is not up to date, or (b) Processor firmware is not up to date. Take a moment to document your processor and Logix versions, then go to AB and check versions available.
