Hi all, I have a LOGO!8 0BA0 with firmware 1.82.01, which i use for my pond drumfilter and automatic waterfilling of the pond. Also i use to measure 2 temperatures and 2 sensors for level detection. The single LOGO delivered with the filter was not enough for the size of my project, so i bought a extension module with 4 in & outputs. All is working perfect, also with LWE on SD card. Problem was that i missed an alert function. Also i never got the communication outside the netwerk working. So I came along node-red, The S7 node and the Blynk node (which i used earlier on an Arduino). This works also without problems including notifications. But the problem is; When i want to use more than 15 S7 in- or outputs, i get bad values (failures) on all. I've tried to play with the cycle en timeout settings, also changing mode settings doesn't help. Als tried without LWE by removing the SD card, but problem stays the same. The program for the LOGO! is large i guess, could that be problem? Running out of memory or CPU capacity? Are the bad values a problem for the performance of the LOGO, because even with the bad values, node-red keeps updating the values to the Blynk app. I attached the node-red flow and the LOGO program in a zip file AttachmentLogo.zip (224 Downloads) |

So you try to access the LOGO! to access, if I understand you correctly. It doesn't work that way because LOGO! cannot be reached directly outside of your home network. The simplest thing is a simple port forwarding through your router, which I do not advise you to do, as this opens the door to an attack on your home network network. The safest would be a VPN connection. There is an example from Siemens. However, a CMR module is required for this. Setting up a Secure VPN Connection between a PC and LOGO! 8 And with the CMR module you can also solve your problems with the alerts. |

I am not aware of anything about a 15 I / O limit. But I don't know either Node Red or Blynk.
