Table 10.6 Output formats for transmission in the PROFIBUS- and the MODBUS-format
(the decimal notation is given in parentheses).
The following points have to be kept in mind from this example:
Decimals are not cut off, but are rounded off.
In case of overflow with a transmission in ASCII-format the identification key "E" (for Format Error) is given to the first
position in the transmission format.
With a transmission in PROFIBUS- and MODBUS-format no identification key is given in case of an overflow. The
number of decimals must, however, not be selected too large, if the value is to be transmitted in integer-format (range
of values in integer-format limited to -32768 to +32767).
