Hello Again Another Query : If we replace the CC with an EU with IM314 and connect it to the S7-400 Rack, Can we have the existing IM308 plugged into the EU to connect more EUs Thanks Navnag

There is no such thing as the last bug in a program |

Hello Navnag had to read your post very carefully to make sure I don't miss the part number "fineprint" and here's some feeback from my side: Never tried this and - as you'd probably already know - this is at least not officially supported. Replacing the CR-700 with an ER700-2 or -3 will work though (done it myself a number of times, see also How do I link an S7-400 with S5 expansion units? for more). Yes, but you can then NOTuse an ER700-2 or -3(again its atleast not officially supported as far as I know). Instead you will need to use an EU185U orEU186U(which is probably not what you wanted to hear, have a look at the 308-3UA12 Expansion Unit Interface Module manual for more). One last suggestion: If you were to google"IM306 DP Slave" (part number 306-1LE01) you may find a third party alternative that will allow you convert your 115U CR's and ER's into DP Slave racks and save you the 463-2, 314, and new CR (and can then even use an 300as the new S7 PLC instead of a 400). You'dstill need tofind a way to get rid of the 308 card in the S5 CR and convert its remote stations to DP Slaves, so this is just food for thought for now. I hope this helps |
