Hello, I have a similar problem:

I have Hercules listening as TCP server. As soon as Hercules start listening I have status 7006 and BUSY bit goes true. TCP Port and IP address are ok.

Have tried to play with AdHoc parameter true or false, but this doesn't change. 

Is my data correct  (array[0...999] of Char) ? 

What am I doing wrong ?

TIA Portal is V13 SP2

Split from No data is received after successful TRCV_C.

Dear Kaulquappe, thank you for your quick reply

I have based my program on the following siemens application note:

https://support.industry.siemens.com/cs/document/67196808/how-do-you-program-the-tsend_c-and-trcv_c-instructions-for-open-user-communication-over-the-integrated-profinet-interface-of-the-s7-1200-s7-1500-cpu-?dti=0&lc=en-WW

What is the best way to save the sent information ?

Hello,

show us picture of TRCV_C block configured. You need use AdHoc in my opinion, it can better handle receive as other type of end recv condition. Look to help how to implement AdHoc mode.

Ok, thank you for the replies

Problem still remains

I have made a pdf with some screenshots

I have tried with adhoc parameter set as true and false, but same problem. A

m I doing something wrong here ?

Btw, I can send data (string) from PLC to Hercules on PC with the TSEND_C instruction

Hello,

maybe you can set LEN parameter of TRCV_C to 65535.

Hello, this didn't help either

I tried 65535 with and without 'adhoc' parameter as true

I get status'8085' with len 65535

Then I tried what is explained here:

https://support.industry.siemens.com/cs/document/79993470/how-do-you-enable-the-ad-hoc-mode-when-you-call-the-trcv-instruction-?dti=0&lc=en-DE

with len=100 and ad-hoc true I get status '7006'

I'm getting quite fed up with this

Any more suggestions ?

Thank you for your help

Hello,

you must do some mistake. How did you change that parameters? Online or set, recompile, download and run? What version of instructions?

Update: Did you look in Help what that Status means?

Hello

7006: Data is currently being received.

This is same status I have and what original thread starter had

Here you see my db which controls the function block

Is Data ok ? (array of char[0..99] )
