Analog inputs

Analog inputs
The tags can be used for various analog signals (see "Measured variable / measurement
type")
Data format: Floating-point number with sign (32 bits)
For the analog input AI0 it is possible to configure running through additional update cycles
during the sleep mode of the RTU, see parameter "Update on value change in sleep mode".
The inputs X41/0 and X41/1 measure at the same time, the inputs X43/0 and X43/1 following
this and one after the other. It is recommended to place measurements with large settling
times on connectors X41/0 and X41/1 to keep the update time and the power consumption of
the RTU low.
