Fail Safe AI Wiring Problem

Cheetos

I'm Using a Fail Safe Analog Input Module 6ES7336-4GE00-0AB0
& CPU 6ES7315-2FH13-0AB0
i have Simulated the Analog I/P using Variable Tables to Force Values & every Thing was Working Just Fine.

When I Tried to Connect a 4-20mA Current Source to the Actual analog I/P module ,I was Supposed to read a Value From the Card on my PG but it Doesn’t read any value . Always Zero

i Attached the Wiring Diagram Used and Snap Shot of the Hardware Configuration of the Module

IS there any thing Different in Dealing with fail safe modules than normal modules” For example” in the H.W Config ,

Thanks

Hi Cheetos,

I am good.

your SF LED is always on that means there is a problem,
open the Diagnostic of module & compare it with manual (Page No.219).
so you can target to the problem. F System is very sensitive if you have not assign the proper parameter.
here is the link for the Industrial Software Safety Engineering in SIMATIC S7.
inthat you can find the all the steps to do the programming & HW.

& for Runtime group you will find the information in the above manual.

Dear Ammy

Thanks for your Fast Reply
i Want to ask you if i Need Programming a Safety Program or it is not necessary?” I have an ordinary Program With no need for the Safety Functions"
and if i have to Crate a Safety Program . is there any sample Program i can use . as this is my First time to deal With F System


The Diagnostic Buffer indicates that i have a Wire Break to the Channels 1:5 . But these Channels are spare and no Signals are connected to them !
only Channel 0 is Connected


Thanks

Access via F-Driver Blocks

In S7 F/FH Systems, the F-I/O are accessed via F-driver blocks rather than via the process

image.

One F-Module driver per F-I/O and one F-Channel driver for each F-I/O input and output

channel used are required.

F-Module driver

The F-Module driver takes over the PROFIsafe communication between the safety program

and the F-I/O. The F-Module driver is automatically placed and interconnected in the safety

program by the CFC driver generator.

F-Channel drivers

In your safety program, the F-Channel drivers form the interface to one channel of an F-I/O

and execute signal processing. There are various F-Channel drivers, depending on the F-I/O

You must place and interconnect F-Channel drivers in the safety program.

For redundant F-I/O, you only need one F-Channel driver for two redundant channels.
