Parameter sets
Parameters only with KEB-Default value
Bit 27 is set in characteristics 2 for parameters, which contains only the KEB default value. These are among
others all security parameters and all write protected parameters.
During loading the specific default values (fr.01 = -5..-8
) these parameters are loaded with KEB default values
if necessary.
Indirect addressed Parameters
The indicator parameter (first parameter of an indirect addressed group) has not a customer default value, be
-
cause the parameter was set to 0 with Power-On-Reset. The parameters belonging to the group have a default
value for each value of the indicator.
Storing the custom-specific default values
A source table is generated. For this one byte is reserved for each parameter in the sequence of the bus
addresses. This byte contains the information for each set, whether the default value is determined from the
parameter definition (= 0, KEB default value) or if the value is stored in the custom-specific storage area (= 1).
This information is determined by comparison to the KEB default value.
For indirect addressed parameters the number of reserved bytes for each group member is equal to the number
of valid values of the indicator. 36 byte are reserved for ud.16 and ud.17, ud.15 = 1...36. 16 byte are reserved
for ps.24
...27, ps.23 = 0...15. The custom-specific default values are stored in the sequence of the bus addres
-
ses (ascending) set depending (set 7..0).
The custom-specific default values for indirect addressed parameters are stored first to bus address (ascen
-
ding), then to indicator value (max. ... min.), then set-dependent (set 7..0).
Example: Default value ud.09, default values ud.16 for ud.15 = 36..1, default values ud.17 for ud.15 = 36..1,
default values ud.18 for set 7..0, etc.
Copy custom-specific default values in the sets
With the bits in the source table the default value for each set is determined either from the parameter definition
for each parameter in the sequence of the bus address or read-out from the custom-specific memory area and
written into the parameter.
Parameters only with KEB default value are loaded with the KEB default value in this case.
Reset of the custom-specific default values
The default values are reset for all parameters to KEB default values in the following cases:
- All parameters are set to default values (initial loading)
-
The version identification of the software changes (new version, or new date code)
- The control type is changed (ud.02 bit 2+3)
The custom-specific default values can be reset manually as follows:
- Loading KEB default values in all sets (fr.01 = -4)
- Storing defaul values (fr.01 = -9)
