Profibus Connectivity

[manav 0]

I need to connect 3 siemens PLCs (model not available) on Profibus with 1794-L34 FlexLogix Processor. What is the right way to go about it? Can I use a Prosoft module for this? What catalog no. can I use? Any limitations on data addressing? Anyone with past experience connecting to Profibus network? Project in pre-sales phase. Need to technically design specs for system.

This might be hard to do. The FlexLogix 1788 daughtercard format is not as popular as the 1771, 1747, 1756, and 1769 backplane technologies. Hilscher makes Profibus adapters for the 1769 CompactLogix, and both Woodhead and Prosoft make them for 1756 ControlLogix. Hilscher might be planning a 1788 adapter as well. You may have to look at this application from a Profibus - to - Rockwell network gateway perspective.

I have been told about a prosoft ethernet / profibus gateway stand alone converter that should work? Anyone with experience about this? http://www.prosoft-technology.com/content/view/full/7473 Will this module work? Edited 20 Dec 2006 by manav

Hello, You can also try this : http://www.novotek.dk/products/hilscher/Datablad_RIF.pdf Bye.

you can select this product instead of having seperate profibus to ethernet gateway select corresponding model based upon the master or slave RIF 1788-DPM PROFIBUS-DP Master RIF 1788-DPS PROFIBUS-DP Slave

use this module on devicenet http://www.pyramidsolutions.com/Expertise_...eWay_AB7605.htm

Do these firms have offices in India? Prosoft does, so I am inclined to go the Prosoft way. I need FlexLogix to be master. And pick up data from 3 siemens PLCs acting as slaves on Profibus network? Any difference in Profibus and Profibus DP? Any literature available on Profibus network? Edited 20 Dec 2006 by manav

Profibus DP - decentral peripherals see link for more details http://www.cpac.washington.edu/NeSSI/27_Ne...%20Profibus.ppt

Good work finding that module, dom33dom. I thought I recalled seeing such an interface but when I did not find it on Hilscher's website I concluded that it was still under development. Using the 1788-format daughtercard as a Profibus DP Master will be the simplest method for accomplishing this connection between S7 and FlexLogix.

Thanks guys, all of this helps. Profibus no longer an issue. Client decided to put the siemens PLCs on ethernet. Will I be able to read these thru kepserver. Kepserver does have a siemens tcp/ip driver. Will it work? Is there any method to msg between the siemens PLC and 1794-L34 on ethernet i/p??

check out this link http://www.kepware.com/Spec_Sheets/Siemens...IPEthernet.html see the link for direct interface between CLx & siemens http://www.sigmansw.com.au/pcs_interfaces.php Kepserver also do that
