Who has experience in communication with a PLC from Thinkwise? In this particular case I need to open a connection to a PLC, send several text strings without opening and closing it with each string, and then finally close the connection. Does Thinkwise have an option for this, or does this have to be performed by the SQL Server? Are there any examples available?

I think the (process flow) connectors are your closest catch, but you’d need a PLC that has some form of a builtin webserver. Seems from your message you can only utilize TCP or the level of ethernet, I don’t think there are any connectors that support this straight out of the box.
Hello
Ricky is largely correct. The Thinkwise Platform can communicate over the following channels:
- HTTP
- FTP
- SFTP (SSH, but files only)
- ODBC
- OLE DB
So whether or not you can communicate with your PLC is determined by it's ability to listen on these channels.
I hope this helps.
Recently we also checked if we could communicate with PLC’s.
As our PLC’s were able to ‘speak’ MQTT, we checked that route and did a succesfull PoC.
The other way to communicate with PLC's most often needs some ‘special protocol’ and in our case was a ‘too far from our bed-show’, and we also needed to use 3rd party library's for it which most of the time cost money and is not within the standard Thinkwise environment available.
I also raised a question here in the community which might give you some more details:
