RG terminals can be configured to make analog current measurements using the CurrentSE
() instruction. When configured to measure current, terminals each have an internal resistance
of 101 Ω in the current measurement loop. The return path of the sensor must be connected
directly to the G terminal closest to the terminal used. The following image shows a simplified
schematic of a current measurement.
6.2.1 Example Current-Loop Measurement Connections
The following table shows example schematics for connecting typical current sensors and
devices. See also Current-loop measurement specifications (p. 220).
