FMM configuration
Configuration
Record set 0x7F
Commissioning
86
n
The mapping of the modules is defined as configuration by the 64byte record set
0x7F.
n
The data record is retentively stored in the CPU.
n
The record set must be transferred to the CPU by the user program by means of a
write command.
n
With the record set read command parts of the active configuration can be read. You
have always to write the complete record set.
n
Each written and valid configuration is only saved if a difference to the existing config-
uration exists.
Record set 0x7F
Byte
0
Mapping
n
The record 0x7F has a length of 64Byte, where Byte 0 ... 63 corresponds to the slot
1 ... 64 of the target configuration.
For the FMM configuration, you must specify for each used slot of the target configu-
n
ration at 'Mapping' the corresponding value that corresponds to the actual configura-
tion.
The following values can be entered at Mapping:
n
0 (0x00) - module is ignored
–
If modules of the target configuration are to be ignored, the value 0x00 must be
used. In this way, gaps can be projected.
n
1 ... 64 (0x01 ... 0x40) - position of the module in the actual configuration
–
'Mapping' corresponds to the value of Slot
tion on which the module of the target configuration is located.
255 (0xFF) - virtual module
n
–
If a module from the target configuration is missing, for Mapping the value 255 for
"virtual module" is to be used.
–
Behaviour of a virtual module:
- The input area always has the value 0, regardless of its size.
- The writing to the output area has no effect.
The target configuration serves as template for the configuration of hardware variants.
1.
Configure your system with a hardware configuration as target configuration and
create your user program. The target configuration represents a superset of all
available hardware variants.
2.
Activate the parameter 'Free Module Mapping' in your CPU.
3.
Activate the parameter 'Startup when expected/actual configuration differs' in your
CPU.
4.
Create the configuration by defining the deviation of the actual and target configura-
tion for the current hardware configuration in record set 0x7F.
5.
Transfer this record set via write command to your CPU.
n
For this use SFB 53 or SFB 58.
n
The address to be used is the diagnostic address of the CPU in the virtual IO
device 'VIPA SLIO CPU' .
ð The configuration is permanently stored in the CPU and immediately active.
