AB ControlLogix MSG Instruction/Gateway Question...

Ok, so I've been through Rockwell Technical Support [yinyang] with only minor injuries, and still don't have the answer to this burning question...

I am attempting to send a message over several networks, through two gateways, and on to an RSSQL server, but I still haven't received a satisfactory response as to whether any method will work, and if so, how to do it...

I am starting the message on a FlexLogix processor via ControlNet, and then crossing one ControlLogix gateway, which houses a ControlNet module, a DHRIO module, and an Ethernet module. Communications over this gateway have been performed successfully to DH+ and to ENet with CNET as a starting point. My MSG instruction needs to go over this gateway to another DH+ gateway, and then over that gateway's backplane, and on to an Ethernet card, which will address a RSSQL server that is looking for 10 type Int words from my FlexLogix processor... We have successfully written to the FlexLogix processor from RSSQL, but not from the processor to the server.

The major issue...

I'm hopping from ControlNet to DH+, then from DH+ in another gateway, over to Ethernet, and onto an RSSQL server. Is this even possible? Can DH+ handle the routing if I use a complete message MSG instruction path from the CNET all the way to the ENET destination PC? Do I need to use routing tables in the gateways? Which instruction type (CIP, DH+, or CIP with source ID), should I use?

As you can see, I have a lot of questions. I've tried variants of all the different message types, and I've even tried using a routing table in both gateways. Right now, I'm just looking for advice...

Thanks in advance!

I'm all [bigears]!

"What your saying TWControls is under RSLinx under a DH+ driver you should see all the paths that are available by doing the DeviceWho?"

No, I was just saying that the info is based off of the same. You won't be able to drill through the DH+ driver and see all the nodes, the same as you can't view all of the nodes with the Ethernet driver, not to be confused with the Ethernet/IP driver.

The main thing about a DeviceWHO is it is a basic request that is somewhat universal that ponycar could use to check his path. I would post an example file but I've never figured out how to upload here
