We will be adding 6 more hoppers that will use an allen bradley PLC to our system. We need to have a way to interface the systems together via a comm link and software so that the main ti & siemens systems can control the new hoppers. Do you have any ideas how we can accomplish this?

Thanks.

 

Hello;

You can try a hardware solution, such as protocol converters that will map Profibus adresses to DeviceNet, for example. See SST, Synergetics, and other manufacturesr. Also, SST makes Allen-Bradley Profibus scanners (slave or master) so you could hook up the A-Bs directly to a Profibus network.

A software solution would involve OPC servers for all networks, and a client application to re

 

They all support Modbus in some way or another.

 

Hi,
It sounds like the easiest way is using opc servers.
I'm quiet sure for each plc (resp each pc/plc interface) is an opc server available.
DX capable opc server are able to talk direct to an other server without an client - so you not even need to programm a client via VB or similar.
Of course opc is not real time, because it uses mostly WinOS.

For S7 interfaces an opc server is available from Systeme Helmholz GmbH ([email protected]).

Hope that helps.

Please take a look at the MARC Omnii-Comm. This product is a protocol converter that can converse using over 60 protocols. The link is http://www.miille.com/PCds.htm
