  1. I am currently trying to message from  a micro820 to a SLC 5/03 (via 1761-NET-ENI ser. D).  In the 800 messaging manual ( http://literature.rockwellautomation.com/idc/groups/literature/documents/qs/2080-qs002_-en-e.pdf) , there is a CIP generic message example that gathers the CatalogID of the device at a particular I address.   My micro is 192.168.10.23. My 1761-NET-ENI is 192.168.10.22. I can get online with both, and I see both processors in Linx.  However, when I execute the example code in the micro, the CatalogID is not the SLC, but the 1761-NET-ENI. All I need to do is write an ASCII string to the SLC 5/03.   NOTE*** Ultimately, I will not need to speak DIRECTLY from the 820 to the SLC--instead the Micro820 will send a CIP message (...a barcode string) to a server that will then send a bunch of data to the SLC 5/03.  So:   BARCODEà[ASCII]àMicro820à[Ethernet]àServer(gets a bunch of data)à[Ethernet]à1761-NET-ENIà[DF1]àSLC5/04(oldPLC)  
  2. Thanks Ken. I'll do just that.  Though, my plan is not looking very promising...
  3. This is somewhat of a tangent, but I am currently trying to message from  a micro820 to a SLC 5/03 (via 1761-NET-ENI ser.

  4. 1747-KE to 1761-NET-ENI.

    Can I do that, or do I have to use RS232 port (DF1) on my SLC 5/04?  I think this will be my cheap answer getting the PLC accessible from our Ethernet/IP network.  The RS232 port is already in use by a barcode scanner, using ASCII read/write instructions.  I would just assume not touch any code I don't have to, so that would let me connect over the KE card instead.  If necessary, I could move the scanner to the KE card and use the PLC port for the 1761-NET-ENI...I think.

    Just a word of validation will suffice...I am out of my element with this old stuff!

      I'll say about Lynn Linse what somebody once said about George Stephanopalous; "If IQ were Fahrenheit you could boil water with the guy". I'm eager to test out a 1747-KE with the 1761-NET-ENI; I'm not certain if those two devices together would effectively bridge Ethernet to DH485. It's moot in this case because there are no spare slots. The SLC-5/03 does not pass through data from DF1 to DH485. The SLC-5/04 and SLC-5/05 have this function when Channel 0 is in DF1 or DH485 mode (and the function is enabled in the status file), but the SLC-5/03 does not. If one of these controllers was replaced with a 1747-L531 processor, then Channel 0 of that processor could connect through a 1761-NET-AIC isolator to the DH485, and the other controllers (and probably the PanelView, this depends on PanelBuilder) would be accessible via Ethernet and ENet/DH485 passthrough function. >>We have two AB slc 503 and 4 panelviews connected togheter on a rs 485 >>network using dh-485.
