Siemens PLC: CPU state
Monitors the current CPU state of Siemens PLC (SPS) devices.
You need to use and configure the special agent agent_siemens_plc which is using the SNAP7
library to communicate with the Siemens PLC. When you are using OMD, everything is already
installed and configured. In manual setups, you will need to ensure that the snap7 library
and python module snap7 are installed.
The CPU state can either be reported as running (OK), stopped (CRITICAL) and unknown
One check for each device is created automatically.
