I would like to know does profibus work on Allen Bradley SLC503. I am trying to control a Festo remote Pneumatic valve block. Any Ideas would be greatly appreciated
 
Yes, I have used an SST card and Siemens COM Profibus configuration software to configure the card and network.

First you need a SST-PFB-SLC card from SST see http://www.mysst.com

The SST-PFB-SLC is a Profibus DP master. You can have upto 32 words of Inputs, 32 words of outputs and the rest of the I/O must be mapped into M0 and M1 which isn't fast so don't use unless you must.

The PLC program just reads the inputs and outputs of the SST-PFB-SLC card just like any other I/O. To make accessing M memory faster you should keep a image of the M0 and M1 files in a N files so all thet data can be copied at once. As state earlier, accessing M files is not fast.

There is a demo SLC program using the SST-PFB-SLC to control a motion controller at http://www.deltacompsys.com/Files/rmcnosync.zip

It is too bad I don't get a commission.

Yes AB SLC works with profibus, you can use SSTech modules to connect SLC Processor to profibus network even Master/ Slave
