1 Internal supply
All voltage measuring ranges can be configured Ä Chapter 1.5.2.2.2.6 “Parameterization”
on page 489.
The calculation of the resistor deviation must be performed via the bridge voltage by the PLC
user program.
Connection of a Resistance Measuring Bridge with external Supply
With the connection of a resistance measuring bridge with external supply, the supply voltage is
provided separately.
