1) (extended range) only with reduced hum injection (see below)
2) In direct island bus integration, Pt100_4 and P100 are connected with 4 wires, R250
is connected with 2 wires.
The P-Bus BIM integration in V4 and later supports P100 4-wire and R250 2-wire,
but R250 must be connected to 4 terminals with jumpers.
Connection diagrams see data sheet N8176.
The resolution with island bus is significantly better than with island bus BIM / P-Bus.
3) This section describes the measured resolution. (Desigo: It is different from the
transmitted resolution that the bus delivers into the AI block and that is transformed
by [Slpe] and [Icpt], see section 10.12.2).
