Note
The following applies when writing the objects:
– Discrete values:
A non-permitted value will not be accepted, the
previously valid value will be retained.
– Concrete values (e. g. lengths, speeds, etc.):
A non-permitted value will be limited up to the next
permitted minimum or maximum value.
Note
Direct transfer of values via the serial interface with CI
commands always takes place in the basis system and
requires conversion into increments.
All parameters are always saved in increments in the con-
troller and are not converted into the relevant measuring
system until they are written or downloaded. All physical
variables (position, speed and acceleration) must be con-
verted into increment values before they can be trans-
ferred.
Further information on converting can be found in
chapter A.4.
All values are transferred in hexadecimal figures; 1 character
represents 4 bits; it is known as a tetrad <Tn>. The first tetrad
transferred contains the higher-value bits of the value.
Generally: Tetrad <Tn> contains the bits b
