Posted 19 Mar 2020 i'm trying to interface a 1756-dnb to a couple devices. i've got the rsnetworx configuration complete and dowwnloaded to the device. when i go online in studio 5000, the scanner is faulted out. the code is "16#0108 connection request error: connection type (multicast/unicast) not supported". what could be going on here? i'm using an l72s cpu and a 1756-dnb/a on the local chassis Share this post Link to post Share on other sites
Posted 19 Mar 2020 Have you checked the versions of firmware in everything? RA has a compatability chart for CPU to DNB and then you need to check field device to DNB compatability. Not all DeviceNet Items are created equal just because they say AB or RA on the face plate. Share this post Link to post Share on other sites
