Split from S7 communication with node-red.

Can you show your node configuration?

Mark the node, export it (menu in the upper right corner) and copy the text here.

Would you care to shed some light on how you perform a write to the PLC (Logo8) in my case? Just sending True to e.q. Q1 does not seem to do the trick.

 Hello,

Pass the Internal memory to switch ON/OFF output of the Logo .

V0.0 = Q1

V0.1 = Q2

V0.2 = Q3

V0.3 = Q4

Use the DB1,BYTE 0 in IoT to pass the required value to activate corresponding logo Output.

IP: LOGO IP , Rack/Slot=0/1

DB1,BYTE 0 = 1=Q1

DB1,BYTE 0 = 2=Q2

DB1,BYTE 0 = 4=Q3

DB1,BYTE 0 = 8=Q4

 Hi,

 Could you maybe share a screenshot of how the variable setup would look like in Node Red?

 I am also currently struggling with sending data via node red to the logo.
