rit03 Posts: 341 Rating: (24)	Dear Forum, I am looking for the alternative of SIMATIC S7-400H, CPU 417H in S7-300 series. Do we have S7-300 Safety PLC which can work on dual redudant system of profibus ring of ET200L modules and provide fault tolerant link to WinCC SCADA station. Regards, RIT03

rit03 Posts: 341 Rating: (24)	Hi, I am looking for advise about using S7 300 safety PLC which can be used for dual redundant profibus ring using fail safe ET200 module. Is it possible? If it is, is it SIL2 compitable. What is the maximum no of I/Os can be used using S7 300 safety PLC and which S7 300 Safety PLC is available for such requirement. Regards, rit03

ET 200L is also not possible, only ET 200M !
	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......

Dreminee Posts: 58 Rating: (2)	Again you need a Redundant system wich is not availeble in the S7-300. And that is what you need for a fault tolerant connection to HMI a H-System. If money is an issue look in the possibility of the 312-H. There you can comply with SIL2 level and redundancy. Wich is NOT possible with an S7-300. Regards, Dreminee
