You will need to give more information about the system.  Is the message only traveling over DH+, or is there an Ethernet link somewhere in the path that the message must take ?   What version of RSLogix 5000 are you using ? DH+ Messaging with the ControlLogix can be a little complicated because of the routing tables you need to enter in each DHRIO module. Transcribe the information from the MSG block (from all three tabs) and post it to this site and you might get some help. Rockwell Automation tech support can help you in French, too; they have a number of francophones in the UK support centre.
