Posted 16 Oct 2019 (edited) Hi, I am trying to set up a remote IO exercise using CJ2M-CPU31/CJ1W-DRM21-> GRT1-DRT with little success. Started with setting up Comms, making Routing table, downloading Routing table, Connecting to DeviceNet in lower left window in CX-Integrator, Devicenet appears in the project and DRM in the right window. From then anything I try to do with the DRM responds with communication error. I got no NS leds, E2 in the DRM and flashing TS on the GRT. I have done the same thing with a CS1 and a CJ1M-CPU11-ETN with almost no problems. Only difference being that with CJ2M I had to start Integrator first, same results with Ethernet, Ethernet FINS/TCP and Direct online USB. The DRMs/DRTs are donated second hand units, so might have some inherited settings? Any suggestions? Geir Update: Actually had two problems, one of the IO-slices in the GRT was faulty and blocked communication. CX-Integrator only seem to work with CJ2M in Auto online USB or USB (Toolbus).
