Do we have such redundant bundle in ET 200S and if ready made bundle is not available,is that possible to make redundant system with it?? Please guide.. Regards.

But to connect a ET200S with a H-System redundant you should use Y-Coupler. More information can be found in the following manual. In chapter 1.2.5 is described how the Y-Link could be integrated in a Automation system. Chapter8 describes how this can be configured in Step 7. Bus links DP/PA coupler, DP/PA link and Y link
	Best regards, INS

Worst Geek Posts: 12 Rating: (0)	Hi INS, Thanks very much for the document. I have seen the fig. 1.4 on page no. 1.2.5. Does it mean that if i take S7-400H redundant and in the lower hierachy IM 153-2 Red and then all the I/Os on ET 200S, it will make redundant system??

DP/PA couplers cannot beoperated in the Y-link. _ The number of nodes in each subordinate DP master system is limited to 31.The total number of slots is limited to 223. _ The configuration frame and the user data frames of the Y-link each consist ofthe frame contents of the subordinate slaves. The maximum length of theconfiguration frame and the maximum frame length for I/O data for each Y-linkis 244 bytes. _ The ET 200M should not be connected to the redundant DP master system viathe Y-link; it should be connected via the IM 153 ._ It is not permissible to cascade Y-links._ Direct communication (slave-to-slave)and equidistance are not possible in the subordinate DPmaster system. I am also attaching tan illustration that shows the different combinations of redundant I/O setups with a S7-400H system. Hope this helps, Daniel Chartier .

Worst Geek Posts: 12 Rating: (0)	Dear Daniel Chartier, Yes, itis really helpful to show the limits ofsuch systems. And one query... "The ET 200M should not be connected to the redundant DP master system via the Y-link; it should be connected via the IM 153." I hope you mean "ET 200S should not be connetcted...... via the IM 153". Or I am not able to understand it? Thanks. Best regards.

It is an extract from the document Y-Link Bus Coupler, Version 2, dated 2000. The confusion comes from the fact that at the time the IM157 was used as an interface for the DP/PA link and the Y-Link, the IM153 was used for the ET 200M. Now the IM 157 has been replaced by the IM 153-2.A newer price list gives this information: SIMATIC DP, IM153-2 INTERFACE FOR EXPANDED TEMPERATURE RANGE IM153-2 COUPLER MOD. DP/PA LINK THE IM153 AND ONE OR MORE DP/PA COUPLERS FORM THE DP/PA LINK DPV1.SLAVE (SUBSTITUTE FOR IM 157) An ET 200M uses 2 IM 153-2s in parallel to connect the I/O modules to the redundant PLCs. I've attached another illustration from the Y-Link document, showing how to connect an ET 200S to a S7-400H system. Hope this clarifies things, Daniel Chartier Attachment S7400H_Ylink.jpg (633 Downloads)
