Hi Dhiyia,

if you want simulate ob40 you need real PLC because it's hardware interrupt that cannot be work with plcsim.

 hi 

at first i know only work with physical hardware , my equation are when have interrupted on analog channel should call OB40  and CPU SF LED lit WITHOUT CHANGE TO STOP MODE 

But in my situation even active ( diagnostic interrupted on module properties and diagnostic group ) and call OB40 and create block inside OB40 to know which channel have interrupted still CPU GO TO STOP MODE  . 

REMEMER MY CPU ARE 315 2DP 

so can any one sent example for OB40 

thank all

 hi,

have a look into the diagnostic buffer and evaluate why the CPU is goinig into stop. If you don´t know how to read the diagnostic buffer, extract it as txt-file and share this file with us.

OB40 can not have any general application sample. A HW-interrupt is depending on the process you are going to controll. for example: HW-interrupt comes because the temperature has reached a specific level and you need to react. Who can know how to react to this, exept you. Do you need to switch off or cool or start any other process? you, as programmer have to know this. Just programm a reaction to a specific event.

You can search for applicaiton samples with OB40. But without looking into anyone of this applicaiton samples I can asure you, each content of the OB40 is different.

hope this helps,

regards,

 hi 

regarding diagnostic buffer i check it the issue was analog module , as say before when choose on properties of module >> general >> select diagnostic interrupted >> channel 0-1 >> group diagnostic >> 4 wire transducer >> 4-20mA >> high limit =21 >> low limit =3 >> deactivate no need channels >>  in physicals connection connect all deactivate  channel together and terminated with

-M . 

so as i know when any issue have been on my two analog signal most be call ob40 

can you create simple example for OB40  and post it 

ohh i forget there is no issue with temperature because the panel temperature are 16 degree 

also CPU TYPE 315 2DP and analog module  7KF02   

can you help me with this issue 

thank you best regards.

 I am not sure I understand what you want to achieve.

Do you want the CPU to *not* stop when there is a diagnostic error? Or are you wanting to *read* the error?

dear sir 

yes I went the CPU NOT  TURN STOP when interrupted triggered , it's most call OB40 then inside OB40 have special ladder diagram to call alarm and view it on hmi 

that's it

hi muntadher,

there is no common code for OB40.

it is a specific reaction to the process when the event comes up.

Example: you want a LED to flash for two minutes when this event happens. So you set a bit in OB40. In the normal cyclic program(OB1) this bit triggers the flashing. It can´t be done in OB40, because OB40 is only running once when the event comes up.

hope the helps,

regards,

 hi 

i know the OB40 will not call until event coming and show online like freeze only active when interrupted triggered so can you create small example with ladder like ( when analog channel No.1 interrupted call OB40 and active bit and show this bit in hmi . 

still confuse my demand so simple ( example with ladder for OB 40 ) 

thank you regards. 

Add OB 82 which is a diagnostic interrupt. It is truigered when error happens and will prevent the CPsu from stopping, in most cases. You may leave it empty or you may add code in it which will run for one scan. OB 82 should have information about the error.

OB 40 is a hardware interrupt and us very different from OB82

OB 40 is a feature of the module which you may or may not configure in the module to perform a task.

OB 82 is a diagnostic interrupt which is triggered only when an error occurs. If there's OB82 present in the program then it is called and that prevents the CPU from going to Stop and if there no OB82 in the program then it will go into Stop.

 HI kalA

As i understand OB40 specify for module hardware interrupted not analog channel interrupted or wire break or signal loss for my case ( channel interrupted ) most used OB82 or what ?? 

also i found in OB40 description 

OB40_POINT_ADDR >> In the case of analog modules:bit field with the information as to which channel has exceeded which thresholds (refer to the module description for the precise structure).

 can you explain that , which OB need to analog interrupted channel ( wire break , signal loss ...etc ) 

thanks . 

dear mop

thank you for your reply , I know OB as general purpose are same but different way , i programing OB86 , OB82 and OB 10 , many post make created make my equation not clear , my demand was so simple , which appropriate OB with analog channel interrupted ( wire break ,signal lost ...etc ) that's it 

also i have small issue that when interrupted triggered the CPU go to STOP MODE ,  if you add OB40 should be SF led lit and OB40 operated without go to stop mode .

I was executed OB40 with s7-1200 and s7-1500 and was very easy 

this is all i have 

thank you with my full respect to your experience 

thank you

 OB 40 has nothing to do with Diagnostics. It can be configured only for violation of high or low limits and will have no effect at all on whether the CPU stops or not.

I just saw your first thread and you are doing fine. All you were missing was OB 82.

Now that you added OB 82 all you have to do is compile the hardware and download it; it should work fine then.

Here's a manual that may be helpful.

 hi mop and kal

thank you too much that take from your precious time to assistance 

mops04

Digital input module SM 321; DI 16 x 24 VDC; with hardware and diagnostic interrupts (6ES7321-7BH01-0AB0)

Thats why I say, only who knows whats the trigger for can know what to program in OB40.

The thing is, when you config a HW-interrupt in your HW.configuration and there is no OB40, CPU will go into Stop. It is not the interrupt that triggers the Stop, but the fact, there is no OB40. Also the entry in the diagnostic buffer says that.

 that's right because the module have high feature ( HF ) , this programing are very easy in s7-1500 , also you can know which channel interrupted even Digital input channels .

 as mop say OB40 can be used even with digital input but the module most be HF and i was programing with s7-1500 and easy but with s7-300 the facilitate not to easy 

so thank you sooooo much will take your comment in my concern and hope to contact in future 

best regards 

pls don't forget your rate

  OB 40 has nothing to do with Diagnostics. It can be configured only for violation of high or low limits and will have no effect at all on whether the CPU stops or not.

 to be more precise, trigger for OB40 can be anything, i.e. a push button on a input-module like this:

Digital input module SM 321; DI 16 x 24 VDC; with hardware and diagnostic interrupts (6ES7321-7BH01-0AB0)

Thats why I say, only who knows whats the trigger for can know what to program in OB40.
