Спасибо. Это пример в V13, может у кого есть в V15, насколько я знаю, нужен тиа портал V13 SP1 для конвертации?

Hi, Serega

yes, you need 13SP1

Way 13 ---> 13 SP1 ---> new versions

 Hello,

Serega 1983

Hello. I apologize for the translation.

In the connection setup example

https://support.industry.siemens.com/cs/ww/en/view/99741844

 FB2 S_RCV and FB3 S_SEND are used, which are not supported by the S7-1200 PLC. Which blocks should be used specifically in the S7-1200 PLC?

 you can't use any blocks, with S7-1200 via distributed connections this service isn't available via any blocks. You need create own driver, all is described in PB DP manual. Then you can communicate from S7-1200 with distributed ET200S station and its serial module, but only with pure serial module 232/485 not 4DF01 Modbus module. In this case that this is Modbus RTU module I'm afraid you can't definitelly.

You're quite long time not here as Loged but hope you'll find this as helpful because from all Forum posts here it is obviously reported that this is possible with standard blocks (not true) and also another reports that this isn't possible (also not true). It is possible but only with 1SI pure serial 232/485 and via your own driver. I did it some long time ago and is functional but lot of work of course. Again, no functionality with 4DF01 Modbus module. It looks like to me you've failed with this and solved via other solution.

eeeehm forget say one important, I did that driver via S7-1200 PB DP MAster module to ET200S DP Slave with standard serial module 1SI. If I'll have access to SW and also HW (hope) I'll try with PN what can be done similary in my opinion.
