Siemens logo

[PaulRohlik]

Hello.
Please help again. I want to connect siemens logo via S7. But I can't get the data from the plc.
Node red is also running on the same guest PC and everything works there.
Can someone please advise?

Very thans.

You might try to use simple tag addresses like M0.1 or Q0.1 If that is working you can dive deeper to the DB.X or similar addresses. I so not know how these are handled inside a Logo.

Thank you. Addresses Q0.1 ... work.
But what do the addresses for:
DB1, Xxxx
DB1, Wxxx
DB1,INTxxx

I've got it :)

Hi, you can use modbus connection to read and write values on Siemens Logo!.

but remember to activate the communication before....

Just went thru this exercise and found the Siemens LOGO uses Port 510 in ModbusTCP into my application of FUXA.

Hi,

Variable mapping for S7 communication is specified in link below. You need to enable and configure S7 communication as server in LOGO project.

Hello,
The problem was in the address format. It works perfectly now :)
