Why 416-5H is the latest while 417-5H is most powerful?

 Thanks 

but we want to know why 416-5H is the latest while 417-5H is most powerful?

logically the latest should be most powerful (in specification)

Hello Hussein,

Yet, there are no much information on S7-1500H. Even the conference tag is still S7-1500.

I will try to answer according to answers I already have from Siemens and also according to my experience with H systems compared to what I read in S7-1500H manual.

1-Is s7-1500 produced for discrete automation not for process automation?

2-Is S7-1517h for non-critical application only

3-Is s7-400h is better than 1517h

4-Is s7 412-5h is later than 414-5h or 418

1&2 - As per Siemens guys' statements in SPS fair last week, the S7-1500 is mainly targeting discrete automation and it's not even for safety/critical applications in discrete automation.

No Safety in S7-1500H.

S7-1500H is not to replace S7-400H.

The redundant controllers for process industry are the ones of 400H controllers which will be still available beyond 2030.

3- As far as it seems and as far as real redundancy is concerned, the answer is YES.

I recommend if you tell me your project requirements then we can discuss what fits you more and what's better for your application.

If processing speed really matters then S7-1500H will be better than most of 400H controllers.

4- Strange question! I will try to answer as far as I seem to understand your question.

First there's no 418.

The 400H family has 412H,414H,416H and 417H as PLCs and 410H as DCS controller.

It all started with 417-4H in late 90s then 414-4H in early 2000 then 412-3H in 2007.

These were the early developments.

Now the latest release is V6.xx CPUs (412-5H, 414-5H, 416-5H and 417-5H).

All V6.0 CPUs have been released together.

And if you meant 416 instead of 418, then the 416-5H is the latest controller in the family of 400H controllers.

But just keep in mind, latest doesn't meant the most powerful.

What really differs is how powerful the CPU is and whether it really covers the application or not.

I've seen many crazy projects utilizing 417 CPU for two standard IO racks.

Aside from chronological order of CPU release, this is the order of CPUs (Aside of  DCS controller 410H) in terms of processing power, memory and IO capacity.

1- 417-5H (Most powerful for large scale projects)

2- 416-5H

3- 414-5H

4- 412-5H (least memory size)

Once again, you have to pick the suitable CPU for your application, not the most powerful and not the latest.

If you have process application where only redundant controllers are required, then you can go with S7-1500H despite what Siemens says or what you can read in marketing materials.

Also Is s7-1500H not support download in RUN , also s7-1500h not support OPC UA

As far as I know, No.

The S7-1500H will not have CiR and will not support download in RUN.

OPC UA is not released for redundant S7-1500H CPU.

If you still need more information like brochures and catalog, you have to contact with your local Siemens office.

Best regards,

logically the latest should be most powerful (in specification)

Responding in broad terms, non-specific to this case.

The latest processors released by Intel for the consumer PC market aims to better the energy efficiency of the processor. The raw processing ability is actually reduced to meet this target; clock speed is also less.

The newest does not mean the most powerful processing. Other attributes may be enhanced from a previous model. This could even include a change in manufacturing techniques, if it is not something tangible like having more memory.

Engineering is about designing according to a need (now and foreseeable future). Buying the most expensive & most powerful does not mean the engineering problem is blown away.

In my view, if you are looking for the most powerful, then Siemens is the wrong solution for you as they underclock the processors. But if you are looking for stability and experience - then the ball game changes.

Best would be for you to have an experienced consultant spend some time with you.

Hello husseinwaledia,

In addition to #dp's valuable post and as I said earlier, you shouldn't care of which CPU has been released after which as long as it fulfills your project's requirements.

You should check the IO count, communication requirements, whether you have fail safe or not and some other things before you decide which CPU will be more suitable for your needs.

The latest release is the same for all H CPUs, Now 412-5H,414-5H,416-5H and 417-5H have the same release date.

Yes, the 416-5 is to be considered the newest "family" member but this new generation as a whole has been born together.

Back to your question, the V6. release (containing all CPUs) has more processor speed and more memory space than V5.4.

As I said it was not logic to use 417H CPU for small and medium projects so Siemens gave us the 412H and 414H.

Then they found that there's a gap in the market that they have to fulfill with a new CPU between 414 and 417. So, the released 416H.

Now the discrete market needs redundant CPUs for large warehouses and so on. So, they released  the 1500H.

This is how it works. It's market needs and the advances in technology.

This would be the best thing to do. You should have a consultant or an integrator you trust.

I also recommend to contact your local Siemens office and ask for a session or presentation on SIMATIC controllers.

 Thus  the latest version of 400H PLC is s7 416-5H

And the most Powerful is 417-5H

Could you notify me the release date of 416-5h and 414-5H and 412-5H?

Thanks

No my friend.

It seems you still can't get my point.

 the 416H is not the latest version of S7-400H. The latest version is V6 CPUs.

This version has 412-5H, 414-5H, 416-5H and 417-5H.

All above CPUs have been released in 2012. you can never say 416-5H is newer than 417-5H or any other V6 CPU.

You can write the part number of each CPU (e.g. 6ES7412-5HK06-0AB0) in the search bar and click on product details. Now, you will see the release date of each CPU.

 I tried to write the part number of 416-5h and 417-5h in the search bar but I cannot find the release date of them 

please put the link of the two versions like the link of 412-5h

thank you
