PLC alerting with SIGNL4
PLC's (programmable logic controllers) are used to monitor and control industrial devices like machines, robots or assembly lines.
In this sample setup use Node-RED and a simple PLC simulator. In Node-RED, configure the S7 node to connect to the PLC and also configure the required S7 variables there. Then, use the SIGNL4 node for alerting (and for resolving the alerts).
