Tag write order

[alattanzi]

Good morning all,

I implemented a client to use with Siemens and Rockwell PLC.
With Siemens it seems i don't have issue.
With Rockwell, instead, sometimes occurs that the plc elaborate data before my application finish to write all the tag.

Can someone explain me in which order the tags are written to the PLC (Server)? Random, by tag name, by order in which i populate the list?

Thank you

before my application finish to write all the tag. I'm not entirely sure what you mean by this. When you call the Write service and provide a List of WriteValue, the server receives that List in the same order. What it does or how it processes the list is implementation specific behavior. The only guarantee you have as caller is that the results in the response are in the same corresponding order as the values in the request.
