Hello guys;
The original question was:
"What is the maximum integer unit for analog input of siemens 300 plc?"
The question was properly answered by Metwally.Mustafa, and the answer can be found by looking at moogie's table, using the rated range lines. The maximum value that will be returned by a Siemens S7 analog card to the CPU (no matter the resolution, type of signal...) is 27648, which will correspond to 100% of the input signal, 20 mA, 10 V...
Anything above 27648 will indicate overflow or error.
Temperature (RTD and TC) cards behave differently, but this is true for all current, voltage, resistance... analog values.
For a bipolar signal(+/- 10 V for example), the range will be +/- 27648, for a unipolar signal (0-5 V, 0-20 mA) the range will be 0-27648.
This is quite standard wiith Siemens S7 PLCs, and is described in the Module Data manual suggested earlier (Chapter 5, Representation of analog values).
Thank you,
Daniel Chartier
