Hi All!

I want to read and write a DB in a S7-317 CPU (317-2FK14-0AB0).  
I setup the Node-RED like below:

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/9/39ce971088265f22b5e4748891f0c2424ecb99ee.png)  
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.

moved to "Industrial" thread as not about creating nodes.

Have you tried other slot numbers like 0 ?

I don't know anything about that node, but the EHOSTUNREACH error generally means that there is a fundamental problem getting to the device via the network.

1. What is the IP of the device running node-red?
2. Are they on the same local network?
3. What hardware/OS is node-red running on?
4. How was node-red installed? Did you use Docker for example?
5. Can you access the device from the node-red system using a different client application?

Hello!

Sorry for the late answer!

The problem was with the network. They were not on the same local network. I forgot to setup the correct static IP for the Raspberry.
