FDI module not respond

Hello!

I have FDI8xNAMUR [EEx ib] (6ES7 326-1RF01-0AB0), connected to CPU 414F-3PN/DP by profibus with IM 153-2 (6ES7 153-2BA10-0XBA).

CPU configured as CPU with F-program. In SM - FailSafe mode is ON. F-program compiling and downloading without any errors. But I can't get the data from the SM. DI signals connected with 2 resistors (LEDs on SM glowing). F-program is only 1 channel DI - see attach. What is reason of that?

It seems a little strange to me - how looks FDI driver is. As I know its inserted automatically and should be setted up automatically too. But it looks like only address of SM is implemented (and how about timeout, crc?)

I tried F-Library v 1.2 and 1.3  In version 1.2 quality code of F_CH_DI = 48, in version 1.3 quality code of F_CH_DI = 0.

Used SW: PCS7 v8.2, CFC8.2, S7 F-Systems 6.1 SP1, S7 F Configuration Pack 5.5 SP12

Thanks much..

Hi,

that is easy. If you followed your other question carefully (  https://support.industry.siemens.com/tf/ww/en/posts/41xf-and-41xfh-what-s-the-difference/160714/?page=0&pageSize=10 ) you now know that this CPU is not released for the use with F-systems for PCS 7.

Only FH CPU is allowed to be used in this configuration.

I find it really interesting that compiling of the HW configuration and CFC does not throw any warning or error.

A lot of thanks!

..that this CPU is not released for the use with F-systems for PCS 7.

Is there some documentation about that?

Myst

Only FH CPU is allowed to be used in this configuration.

And about this also?

I find it really interesting that compiling of the HW configuration and CFC does not throw any warning or error.

No errors, but warnings appears. I guess it's not important  It says, there are unsupported ET200s on the profibus. But this ET200s do not participate in F-program. See attach.

Hi,

yes there is a documentation about this. It is called released modules for each PCS 7 version.

For PCS 7 V8.2  as example you can find it there: https://support.industry.siemens.com/cs/de/en/view/109736547

Any module not listed there may not be used with PCS 7.

EDIT:

As you may know in Siemens there are two different ways for safety programming.

• Distributed safety for the use in factory automation environment without PCS 7 and
• S7F/FH-Systems for the use in process automation environment with PCS 7

Each of these systems use its own hardware. For a fast introduction see the following manual: https://support.industry.siemens.com/cs/ww/en/view/12490443

Following note was taken from the mentioned manual (quite a little old, not all CPU inside but in total very understandable):

Note

You can use the following F-CPUs in S7 Distributed Safety: IM 151-7 F-CPU, IM 151-8F

PN/DP CPU, CPU 315F-2 DP, CPU 315F-2 PN/DP, CPU 317F-2 DP, CPU 317F-2 PN/DP,

CPU 319F-3 PN/DP, CPU 416F-2, and CPU 416F-3 PN/DP. Note that these F-CPUs can not be used in S7 F/FH systems.

You can use the following F-CPUs in S7 F/FH Systems: CPU 412-3H, CPU 414-4H, and

CPU 417-4H. Note that these F-CPUs can not be used in S7 Distributed Safety.

Thank you very much, it was very useful for me.

I work with STEP7 (and not with PCS7) and use both type of f-programming, everything operates good )). But I didn't know about that limitations PSC7 with. 

p.s. so, I'll have to use 414-5H.

Hi andr11,

yes you may use 414-5H if your program will fit to the memory of the controller. Otherwise you have to go with 416-5H.

For PCS 7 I would recommend to use 410-5H because this controller is scalable and you do not have to know the final size of your program in advance.

You can increase the amount of PO that can be downloaded to this CPU in steps of 100 PO.

So you have ONE controller for any size of program you want to download. No need for hard decisions which may be the correct controller.

Keep in mind: 410-5H can only be used with PCS 7.
