Hello Sundar this is what I'd pick as a replacement (relevant for your first posting, you justadded another posting while I drafted this one): 1.) S5: Central Processor-- 6ES5 188 - 3UA11 This is justa 19 inch S5 rack which also contains the power supply in thebottom Replace with:S7-300 mounting rail with 5 Amp 307 Power supply (6ES7 307-1EA00-0AA0) 2.) S5: Central Control module-- 6ES5 928 - 3UB12 This is your S5 CPU (with 64 KByte RAM/max S5 program size) Replace with: 317F-2 PN/DP CPUwith 1024 KByte RAM (6ES7 317-2FK13-0AB0). This will easily do the job, has Ethernet on board for SCADA comms and will give you the ability to integratesafety if needed as part ofthe upgrade or in the future. You can also easily get away with a 315F-2 PN/DP CPU (6ES7 315-2FH13-0AB0 with 256 KByte RAM). The main"downside" of it is thatit has only one cyclic interrupt OB which more foten than not becoms a "bottleneck" (especially if Safety is used plus some PID loops) and which may or may not be enough to replace what was in the 928 (which offers9 cyclic interrupts, but you'd rarely use all of them and even if so, you'd simply use interrupt "counting" to achive the same in a 317). 3.) S5: Communication processor-- 6ES5 524 - 3UA13 This is a serial comms comms card. The physical interface depends on the submodule that is mounted in it which could be either RS232, TTY or RS422/485. Replace with:CP340 or CP341(choice depends on what the CP524 is used for in the S5) I hope this helps Cheers Fritz |

Hello again Sundar just qucikly a fewthings conenrning your second posting: 1.) Use IM360/361 (allows for up to 3 Expansion racks, your 365 can only do one expansion rack) OR go for ET200M with IM153-2 which can house 12 I/O cards (this way you get away with a total of only two racks, CPU rack and oneProfibus I/O rack which will physically fit into the space of the exisiting S5 rack). 2.) Use 6ES7 331-1KF01-0AB0 as S7 AI to replace theS5 6ES5 460- 4UA13(this isTHE most suitable replacement for your type of S5 AI, note too that the S5 card is 8 channel AI you opted for a 2 channel S7 AI). 3.)The DI, DQ and AQ cards that you selected are fine 4.) Unless I counted wrong and assuming you go for the above AI card, you will just get by with one CPU rack and one I/O rack(15 I/O cards in total and one CP which will occupy all 16 available Slots even if you stick with the IM365). I hope this helps Cheers Fritz |

Thanks fritz, Why i am choosing IM 365 means customer needs send & receive interface module. But 360 & 361 having only send or receive capability. what r the difference b/w this two.I prefer to use only two racks. how can i choose interface module. i dont want to go with ET-200. can i transmit & receive data between two racks using two IM360 (each rack having 1 IM360) Where i should insert the C7 control system. i attached the details below.

Hello Sundar C7's are history, don't go down this path (http://support.automation.siemens.com/WW/view/en/28375320)! If they would still exist, you also wouldn't need an extra CPU as a C7 wasnothing else but a CPU and HMI Panel combined into one piece of hardware (and in your case have an IM360 on board too). As for the IM360/361 vs IM365: An IM365 always comes as a pair of two IM365 with a fixed 1 meter long pieceof cable between the two. One IM365 sits in the CPU rack, the other in the (one and only possible) expansion rack 1. An IM360/361 combination on the other hand has the same "SEND/RECEIVE" functionality asan IM365 pair except it is modular (and slightly more expensive than its cheaper IM365 cousin). IM 360 "sists" inSlot 3 of the CPU rack, an IM 361 "sits" in expansion rack 1 and a connection cable (seperate purchase, comes in 1m, 2.5m, 5m and 10m lenght) connects the two. If you need anotherexpansion rack (2), it too will have an IM361 which will now be connected tothe IM361 in expansion rack 1. The last possible expansion rack 3 will also needan IM361, which will now be connected tothe IM361 in expansion rack 2. I trust this helps and clarifies things Cheers Fritz |
