Siemens PLCs over PROFINET and S7 with DigiOS.

The line gets its work from DigiOS over S7 communication or OPC UA and reports its state back, with safety logic staying in the controller.

How DigiOS works with Siemens PLCs over PROFINET and S7

On your plant's PROFINET network, DigiOS talks to S7-1200 and S7-1500 controllers through S7 communication, which reads and writes values in data blocks, or through the S7-1500's built-in OPC UA server. An edge gateway in your building holds the connection.

About Siemens PLCs over PROFINET and S7
Siemens SIMATIC S7 controllers run many production lines, and PROFINET is the industrial Ethernet network that connects them to their devices.
Your account
The devices, printers and controllers stay yours, on your network. DigiOS reaches them through an edge unit in your building, or from the browser.
If a document is rejected
A scan, a label or a command that fails shows on the device and in the exceptions list with its reason, and nothing is sent again on a guess.

Questions about Siemens PLCs over PROFINET and S7

Which Siemens controllers work?

S7-1200 and S7-1500 are the usual ones. Older controllers can work through a gateway. Tell us the model and we confirm.

Does DigiOS speak PROFINET as a device?

DigiOS sits above the I/O layer. It reaches the controller over S7 communication or OPC UA on the same network, and the controller handles the I/O.

Is OPC UA better than S7 communication?

Where the S7-1500's OPC UA server is on, we prefer it, because it names values and has its own security. We pick with your controls engineer.
