Automation virtual commissioning : PLCSIM advanced 2.0 with C#
This is is a short demonstration of a co-simulation between Siemens PLCSIM Advanced and C#.
The goal is simple : have the ability to conditionally change inputs.
We’ll do a proof of concept with a small exemple for a safety relay monitored by a feedback.

Monitor a host from a Zabbix Agent (ping / ICMP)
Monitoring my Raspberry Pi network behind NAT is easy using OpenVPN and Zabbix agent/server.
In a few cases, I need to monitor hosts without any possibilities to install OpenVPN and Zabbix agent on it (switchs, routers, wemos, arduinos…).
