Greetings,

Any chance of an update to this package so it can access the full 64k address space for holding registers?

Thanks!

Dear TIBI68,

          Is possible to use library MBMA341 even if the CP341 is in ET200M rack connected to the CPU by Profibus?

Also

Because of the FB MBMAREQ uses as input parameters "LINK" provided by the FB MBMA341, It's not better to call MBMA341 before MBMAREQ?

I'm asking those things because using ibrary MBMA341 the CPU goes in STOP.

I'm using blocks FB10, FB35 and FB7, FB8 from your library. I followed manual but every time I use FB10 and FB35 the CPU (S7318 2AJ00-0AB0) goes in STOP.

Have you any idea?

Thanks!

We have the library running in plants with CP in ET200M without any issues. 

The MBMAREQ and MBMA341 are communicating over the LINK data block with each other. Calling the MBMA341 first does not make any sense because it does not know what to do. The request need to be given to the block first.

Regarding the CPU stop, try to adapt the example project to your system and check if it's working. I believe you should start there first. 

Good luck.

There is only the example for CP340, correct?

I'm using CP341. So I have to use the example but with FB 10, 35, 7 and 8 of CP341 library, correct?

Thanks!

Correct.

If you have any problems let me know. 

You can also send me your email in PM if you want, I do not visit this forum all time. 

Best regards. 

Hi

How this function can be used in TIA portal v13?

I can not migrate into tia!

Sorry my friend but TIA is not supported because I don't use it and have no way to test it.

Best Regards.

 thanks for your answer

If you can the source code send to me, maybe I can create this fb for tia and share in this froum

Good day!

First, I want to thank you for developing a Modbus driver for CP341, which does not need h/w dongle. I'm going to use it in my project.

I have a one quesetion about that FBs - can I somehowrecognize a lost of connection to slaves? For example, I want to know, that slave device does not answer my requests (wire break or power problems).

I've read a manual, but I havent seen any info about connection faults.
