Hello,
no, the PTP module does not convert / omit any characters.
Did you look at your send DB in HEX notation? Are all bytes correct?
You should not use a STRING, an ARRAY of BYTE is the easiest way.

Hello,

sry, hard to recommend exactly something because other infos are missing and also from pictures other language used than English. Really hard to say, what you do with RECV, how you control that procedure, not interference with SEND, not mix memory/buffer... Simply so much reasons can affect your functionality. You can attach more pictures especially:

1. HW cfg of module, more options to see and also use of correct HW ID of serial module.

2. options with SEND/RECV buffer. Info about different memory /buffer used with SEND/RECV also missing. Here can be basic problem generally with other procedure overwrites.

3. RECV block which working ok due your info, picture from ONLINE.

4. chcek that other blocks SEND_PTP can exists in library with modules, maybe some mix has been done.

5. other problem can be use of not correctly working serial PC aps, here I recommend proved Hercules app, check web. There you can see also hex representation.

6. check again your help about used blocks in TIA help, there are parameters which need to be checked programatically, also with some combination probably.

7. CPU diagnostic buffer can be helpful also.

In some other cases, recompile complete HW and SW can be helpful to see maybe some inter work missunderstandings, you can simply something forget and your result can be bad. If I ommit HW problem of module, my first idea is that you mix some memory from other processing or some mix with SEND/RECV.
