Hi, I have a problem trying to send a message from a 1756-L73 controller with an 1756-enbt/a to a 1769-l24er controller via ethernet and vice-versa... pretty sure that my problem resides in the address but I can´t figure what I´m doing wrong:
Both controllers are connected to the same router and both visibles by RSlinx and RSnetworx
The 1756-enbt/a IP address is 192.168.1.16, and it´s located at slot 1 of the rack
The 1769-l24er IP address is 192.168.1.17
The configured messages are:
In the 1756-L73:
MSG1: CIP data table read
Source: ESTADO_PLP_READ (DINT)
Destination: ESTADO_PLP_WRITE (DINT)
Path: 1, 192.168.1.17, 0
Extended error code: 16#0000_0311
MSG2: CIP data table write
Source: ESTADO_PLP_WRITE (DINT)
Destination: ESTADO_PLP_READ (DINT)
Path: 1, 192.168.1.17, 0
Same error code!
In the 1769-L24:
MSG1: CIP data table read
Source: ESTADO_QLP_READ (DINT)
Destination: ESTADO_QLP_WRITE (DINT)
Path: 0, 192.168.1.16, 1, 0
Extended error code: 16#0000_0311
MSG2: CIP data table write
Source: ESTADO_QLP_WRITE (DINT)
Destination: ESTADO_QLP_READ (DINT)
Path: 0, 192.168.1.16, 1, 0
Extended error code: 16#0000_0311
Can anyone help me addressing the messages??
TANK YOU!!!

Re: Problem addressing messages
Hi santiagoplc.
that error code indicates that the port is not available.
your path information should be in the following format: local communication module,local port, destination IP address, etc.
you can ignore the "local communication module" on the compactlogix units if you are using the built in ethernet port.
try changing the path on your controllogix PLC to 1,2,192.168.1.17 <-- port 2 is the ethernet/ip port.
try changing the path of your compactlogix PLC to 2,192.168.1.16,1,0 this will send data out of your ethernet/ip port and the "1,0" should send the data along the backplane of your controllogix to the CPU.
I haven't had to do communication between PLCs in years so I might be a bit rusty.
