5.2.1
Write parameters
Description
Parameters which can be written into and displayed are indicated by the prefix "P".
These parameters directly influence the behavior of a function. The value of this parameter is
saved in non-volatile memory (EEPROM) as long as the appropriate option was selected
(non-volatile data save). Otherwise, these values are saved in the volatile memory (RAM) of
the processor, which are lost after power failure or power-off/power-on operations.
Examples of the standard notation used throughout our manuals is given below.
Notation examples:
P0970
P0748.1
P0819[1]
P0013[0 ... 19]
5.2.2
Monitoring parameters
Description
Parameters which can only be monitored are indicated by the prefix "r".
These parameters are used to display internal quantities, for example states and actual
values.
Notation examples:
r0002
r0052.3
r0947[2]
r0964[0 ... 4]
