I'm trying to exchange some data between two controllers. I've used a manual which describes Tag Datalink communication. Everything works fine on the Bradley side, which means I can read values from Omron without problems. However, on the CJ it isn't working. In the Network Configurator I get error every 10 sec (Tag data ling error, code 03D5) and cannot read any data from AB. When I open Connection Structure Tree I see that the input tagset from AB has 'Broken path (0000000000000)' and Unknown Device right next to IP address. I've tried using EDS from the Rockwell as well as uploading it from AB PLC directly - I don't know if it might be EDS issue. The only thing I noticed that inside CJ2M-EIP21 EDS it says that Ethernet/IP is Class 1 connection, however in the 1769-L35E EDS Ethernet/IP is Class 2 connection. Have anyone ever had such a problem?

Communication L35E Ethernet and RS232
wrager69 posted a topic in Allen Bradley / Rockwell Automation
I was wondering if I can use the ethernet and the rs232 interface at the same time with two different devices. A computer with RSLinx on the ethernet and and Arduino RS232 on the RS232 with DF1? -
Good Evening, Plant Configuration: Micrologix1100 (Filler) / CompactLogix L43 (Cooler) / CompactLogix L35E (Packaging) under the same network. Mission: Filler need to comunicate with the Filler and the Packaging using the MESSAGE protocol (DONE) Cooler and Packaging need to communicate eachother using the PRODUCER/CONSUMER Protocol (DONE) Question: I tryied to perform a physical connection failure for see how P/C and MESSAGE protocols set variables after the failure. And I noticed that they keep the last state. For the MESSAGE protocol i used a wiping timer that every 200ms set the INT sent by the Filler to 0 and it works. But for Cooler and Packaging I'm trying to do things in a better way because they exchange bigger User Data Types. Is it good to COP an empty DataType in the consumed tag every X ms, or there is a better way to wipe the tag in case of disconnection? Thanks in advice, Teo.
