Hi all,
I'm working on a project where several suppliers deliver hardware and I want to connect to this equipment with an OPC server. Most suppliers used Siemens PLC's.
As far as I understand now I can connect to these devices by means of an S7-connection, but since I don't have their project data I need to configure an S7-connection with 'unknown project' and make sure the IP-address and TSAP are correct.
I've been reading a lot about this, but still have some questions:
- Will this connection potentially work, although I'll never merge the networks (I can't make a multi-project since I don't have their project data)?
- Do only I have to configure this connection on the OPC side or does the supplier also need to configure a connection with 'unknown project' in their device?
- What aspects of the connection should I especially take care of?
Thanks in advance for any advice, comments or ideas.
P.S.
- Communication with the OPC server was succesfull with an ET200S we programmed ourselves
- I'm using STEP7 v5.5
