Modbus TCP (via CP443-1 adv): FB Job_List_SCL (FB912) not running, no job started

Hi,
what show the output parameters BUSY, DONE, ERROR, STATUS and Save_STATUS?

pdf is enough.

The entries in the diagnostic buffer exist, because you don't have a license. Without a valid license the communication works, but you get entries in the diagnostic buffer and on STATUS A090 is shown. It is not an error, only a status information. (it is described in the manual too)

The original job_list has 5 jobs. Your block has 8 jobs, so it is modified manually. You can do this, but you must execute the instruction for modifying as it is described in the pdf for the addon blocks. 
In the online idb of the job list I see, that no job is running because the TON timer doesn't run.
I inserted the original job_list in your program and downloaded the project into PLCSIM and the timer and the job_list works. So your modified job_list has a problem.

 I forgot to be more detailed. It is about the second entry. It mentioned  "FB number:    108" which is the FB of the MODBUS BLOCK.

but you haven't mentioned anything on the job_list?

Both entries in the diagnostic buffer occur regarding the missing license. You can also have a look in the manual, it is described there.

I seems that you changed the job_list block for scl source in AWL/KOP/FUP editor and this causes the problem.

• When I take the original scl source for job_list block and change it from 5 to 8 jobs in SCL, then it works.
• When I take the original scl source for job_list block and change it in AWL/KOP/FUP editor from 5 to 8, then it doesn't work.

I seems that the compiler compiles it differently. So I assume that you use the AWL source for the job_list and change it in AWL/KOP/FUP editor or you use the SCL source and change it in SCL editor.
