I want to read and write a DB in a S7-317 CPU (317-2FK14-0AB0).
I setup the Node-RED like below:
I tried to change slot numbers, I tried to modified the IP of the CPU as troubleshoots, but nothing helped. I do not find a proper description to setup the communication between S7-300 and Node-RED with Simatic Manager. I know, that in TIA there is additional steps to do, but I want to use Simatic Manager with S7-300 CPU!
What am I doing wrong? Why the CPU is offline?
I only use 1 variable. I tried other as well without any success.
