not.
this port is not Ethernet...
only DH or RS232
(with hardware but in this time do not know the reference of the card but I know, it is quite expensive) |

Messer, thanks
I found the price 1761-NET-ENI in Brazil is R$2000,00 I believe that EtherNet/IP Client/Server Communications Module
and
DH-485 to EtherNet/IP Communication Module
it are too expensive, but I think better to change the CPUs
I am going to try this solucions.
Thanks |

If you don't need a lot of I/O you could take a look at the Micrologix 1400. Has 2 serial and one 100 mhz ethernet I/P port. I/O can be expanded locally. Uses Logix 500 software.
Can do Modbus messaging also. I am using some for Modbus 485 rtu to PLC 5 ethernet bridges. Also has dublu int's. |

You could set up a 1400 as a data server for the DH485 network. Would most likely be cheaper than a prosoft bridge or any of the other bridges out there. (Have had some bad experiences with several.) Use a AIC to link one of the serial ports to the DH485 and pull - push data through the ethernet with a simple program in the micro.
There aren't any real cheap solutions out there. The only other solutions off the top of my head is to:
1. replace one of the 5/03s with a 5/05 (expensive) or
2. find a old pc and a serial pic or usb adapter and us it as a data server with RSLinx. I actually did this around 15 years ago with a 5/03. Not the fastest thing out there but it works. |

(allvaro, rockwell is good but too expensive, you have to opt for a cheaper brand of hardware and I will not talk about omron or Siemens because it is too expensive... but Unitronics eg, very cheap and has modules for all query.
Please note: I am not a reseller, you understand ...
hug)
allvaro, rockwell é bom mas demasiado caro, tens de optar por uma marca de hardware mais barata e nem vou falar de omron ou siemens mas por ex unitronics, muito barato e tem modulos para tudo, consulta.
Atenção eu não sou revendedor, entendes...
abraço |

| AB claims that the DH485 port will not directly drive a multi-drop network by it's self. |
