Modbus S7-1200 Siemens Example Query

Hi All

If you look here at the siemens example

https://support.industry.siemens.co...rtal)-for-the-simatic-s7-1200-?dti=0&lc=en-ZA

I had a read and then started my own read/write

My question is in siemens example in the DB's there are DataTypes of "type" (see pics) - If I put the datatype into my own code its red with an error - what is the type and how do I establish this - I have had a god look and cant find anything to help

Hello.
It's a user defined datatype.

You can create your own dataype that matches the one in the example.
Go into the "PLC data types" folder of your project and create a datatype.

From the example project, go to the "PLC Data Types" folder, and copy the "typeModbusMaster" and paste it in your project.

Got it

Thankyou both of you

Also in modbus_com_load how do I set the stop bit ?
