  1. EIP Class 1 Connection Data Structure

    I found a solution. The gateway I am using is supposed to have the capability to swap bytes. I tried to set this directly in the gateway and it wasn't working.   I ended up using a few BTD instructions to re structure the values and now its working correctly.
  2. EIP Class 1 Connection Data Structure

    Which ordering of bytes is Allen Bradley using? My gateway is configured as no byte swap so it should pass the data onto AB the same as its received. The specification from the Profinet slave device is Big Endian/Motorola)
  3. I am needing some guidance on an application I'm working on. I'm trying to obtain data from a profinet slave device to an Allen Bradley compactlogix PLC. I am using a Prosoft PLX82-EIP-PNC profinet-/ethernet-ip gateway as a median to allow me to access the profinet data. In RSlogix5000, I have created an EIP Class 1 connection for the profinet controller and AB PLC (248 words of input data, 248 words of output data). The same structure is created in the profinet controller (248 words of input data, 248 words of output data). The profinet gateway and PLC are communicating properly. From my profinet slave device, I have a specification that the data is structured within a 23 byte format. Connecting to my profinet gateway, I can see this data. I have attached an image that shows the specification of the profinet data and the data values displayed inside the profinet controller. From the PLC side, I'm needing to be able to see this data and put it in meaningful values. I am using the profinet slave device's internal temperature as an example to work towards. I'm not sure the best way to be able to handle this data and structure it to a meaningful value inside the PLC. (I am using the device's internal temperature as an example to try and get into the PLC).   Thanks,

    I did have a look on the 1761-NET module and the serial port is available. I'll consider this option also.   Many thanks

    Ok. I was looking at their DSPLE000 model which is the most basic. For my application, I just need to pass some basic data back and forth. Thanks for the input.

    I checked into the Red Lion DSPLE000 module. Looks pretty straight forward.. Basically what I want to do is read an analog input on the SLC and pass that value into the compactlogix also. There are more details but basically I'm passing data from the SLC to the compactlogix so the compactlogix can do its own control.    I guess this converter would work for that purpose.

    Hmm, interesting.. Maybe my real best option is to replace the SLC/03 with a SLC/05. Or to recreate the communication median around the DH485 instead of ethernet.    
  9. Anyone have any suggestions on the best way to pass a little bit of data between a SLC 5/03 controller and a compactlogix? The current problem I'm working through is the SLC 5/03 does not support Ethernet (only RS232 and DH485). So now I'm trying to find a solution.   Thanks,
