Doing a project in which I will need to connect a DirectLogic 205 to a Logix 5000 processor and send a few decimal values to the 5000 cpu.

I have E-Net available on the Logix rack and an available serial port on the CPU. What (in your opinion) would be the best way to transfer data from the 205 to the 5000. DCM Module?? and what type, as I see there are a few different Modules

Any Logic examples would also be helpful..

Thanks

It depends on which DL205 cpu you have and what ports are available on it. MODBUS RTU is the likely serial protocol, so you need to check the Logix 5000 and see if it supports MODBUS RTU natively as either Master or Slave.

It might be possible to do MODBUS TCP/IP. If so then again depending on the DL205 processor, you might be able to add a H2-ECOM100 to the DL205 rack to do this.
