Hello,
I have a SLC DH+ (Slot0, Port1) and I am trying to use the MSG (SLCRead) instruction in Logix5000 to get data out of the SLC.
I cannot simply add my DHRIO card to the I/O config (please see thread(http://www.plctalk.net/qanda/showthread.php?t=58507))
I must manually address the SLC using the MSG instruction in the Backplane,Port fashion.
Anyone familiar with using this connection method?
My System looks like this:
SLC CPU Slot0, DH+ Port1
ControlLogix CPU Slot0
ControlNet card (master) Slot 3, Node 1
ControlNet card (remote I/O) Slot 0, Node 3
DHRIO Card (on remote I/O Rack) Slot 9, Channel 'A' (#2)
I appreciate any help here, as I'm so close, yet so far
Thanks!
