The ProfiBus is connected via copper cable. Also, is it alsorequired to use this Safety protector between F-DI and F-DO and vice-versa? regards, rajudon

Hello rajudon;
The seperator moduile is uused when you have a mixture of standard and failsafe IO modules on your S7-300/ET 200M, and you need SIL3/PLe certification in your project.

See the following explanation (from the second FAQ in this link)
http://support.automation.siemens.com/WW/view/en/7110199

You can also use a combination of fail-safe and standard input/output blocks in an ET 200M station. To attain safety class SIL 3/PL e/category 4 with combined operation in the ET 200M station, you need the isolation module if you are using the following modules of the ET 200M or their predecessor versions

Module	Order number
SM326, 24DI, fail-safe	6ES7326-1BK01-0AB0
SM326, 8DI, NAMUR, fail-safe	6ES7326-1RF00-0AB0
SM336, 6AI, fail-safe	6ES7336-1HE00-0AB0
SM326, 10DO, fail-safe	6ES7326-2BF01-0AB0
SM326, 8DO, fail-safe	6ES7326-2BF40-0AB0

The isolation module separates the potential groups of the fail-safe and standard modules. In this case, the standard I/O modules must be slotted to the left and the fail-safe modules to the right of the isolation module.

Hope this helps,
Daniel Chartier

What I can understand going through the FAQ, is that if we use the latest versions of the F modules (mentioned below), we do not need to use the Safety Protector at all. SM326, 24DI, fail-safe 6ES7326-1BK02-0AB0 SM336, 6AI, HART, fail-safe 6ES7336-4GE00-0AB0 SM326, 10DO, fail-safe 6ES7326-2BF10-0AB0 SM326, 8DO, fail-safe 6ES7326-2BF41-0AB0 But, using modules from this range, in the S7 (V5.4.5) HW configuration under the "operating parameters" Tab of the IM153-2, it still shows the requirement of F Separator Module with its separate active bus module (though it shows wrong MLFB of the Safety Protector Module). Why so? regards, rajudon Attachment Safety Protector_S7 HW Config.JPG (657 Downloads)

Why so? regards, rajudon Hello, If you do not want to use safety protector, then you have to put the failsafe modules beside IM153 and then the standard modules. In your attached picture, you put two standard modules first, so you have to use safety seprator module. Try to change it in HW config. It should work. Hope this helps.

Why so? Hello rajudon I'd say this is abug in Step 7 (you do NOT need the Safety Protector Module with the new F-I/O cards as per the FAQ that you already have, so you can also ignore the incorrectly shown part number for it). The way I see it, your configuration is ok for up to SIL3/Cat.4/PLe without the usage of the Safety Protector Module. For your info, I get the same silly display as you with Step7 V5.5. SP2, so it is not because you have an older Step 7 version. I would urge you though to seek clarification from Siemens via a Support request and keep us posted here about the answer. I hope this helps
