Diagnostic Bits
Bit numbers 0 and 1 are reserved for diagnostic functions, whereas bit number 2
does not have a function.
E = error bit (0 = no wire break; 1 = wire break)
O = overflow bit
Analog Outputs
The following table shows the analog value representation of the analog electronic
modules with analog outputs:

Note
The following applies to temperature measurements: In the overrange and
underrange, the gradient of the characteristic curve at the point where the
linearized rated range is left is retained.

Analog Value Representation for the Measuring Ranges
of the Analog Input Modules in SIMATIC S5 Format
Introduction
The tables in this section contain the digitized analog values for the measuring
ranges of the analog input modules.
Format Calculation
The SIMATIC S5 format is calculated in the analog module on the basis of the
SIMATIC S7 format. The overrange in the two formats is therefore the same size
(approximately 17.6 %).
