a)
The store counter can be used for monitoring parameter changes, for instance. The store counter is incremented by one on each parameter
change via the HMI or serial communication. When the counter reaches its maximum value, it will roll over. If the factory settings are restored,
the counter is cleared.
b)
In case of a warning, the value 255 is stored in V169. This enables the master to continuously read only V169.
c)
If the optional DNP 3.0 module has been installed, the DNP 3.0 communication protocol is automatically selected.
d)
If the optional communication module is not installed, a warning of a faulty communication module appears on the LCD together with the fault
code.
