Thanks & Regards,

Mihir

Hello mithir.2286

Yes you can use SNAP7 for example.

If you have a S71500 PLc for example then you could also use a OPC UA Connection:

Here a little example:

Thank you so much for your reply,

but  my client don't have OPC Driver they have only TIA Portal with HMI Display so start with sharp7,

Connection is successful but not getting any program block data.

Please guide.

Hello Mihir.2286

Be sure you have activated the Put/Get Kommunication in the security settings of the PLC and use only non optimized Data Blocks...
