4. Activate FMM via the CoE object 0x3000:02, so that the FMM data is stored reten-

ð
Your system is now ready for operation. An additional adaptation of your PLC
program is not required.
4.5.5.2 FMM configuration
The FMM configuration is made with the CoE object 0x3001. The CoE object 0x3001
consists of 64 subindexes, on each of which a FMM value with 4bytes can be written.
Here, the subindex represents the slot Slot
target
of the target configuration. For the FMM
configuration, you must describe the corresponding subindex with an FMM value for each
occupied slot of the target configuration. It has the following structure:
1 Subindex or Slot
target
2 Mapping or Slot
actual
3 00h (fix)
4 I/O
target
5 FMM
Slot
target
- The subindex of object 0x3001 represents the slot from the target configura-
tion. The FMM configuration always refers to the slot of the target configura-
tion.
Slot
actual
- Slot of the actual configuration on which the module of the target configura-
tion is located.
Subindex - The subindex for the FMM configuration results from the Slot
target
. This value
is identical when configuring hardware variants.
Mapping - Mapping corresponds to the hex value of Slot
actual
i.e. the slot of the actual
configuration on which the module of the target configuration is located.
If a module from the target configuration is missing, for Mapping the value
FFh for "virtual module" is to be used.
If modules of the target configuration are to be ignored, the value 00h must
be used for Mapping . In this way, gaps can be projected.
00h - This value is fixed.
I/O
target
- Number of input and output bytes of the target configuration. This value is
identical when configuring hardware variants.
FMM - The value for FMM consists of Mapping & 00 & I/O
target
.
Behaviour of a virtual module:
n The input area always has the value 0, regardless of its size.
n The writing to the output area has no effect.
– For modules with variable IO size, you have to specify the size to
which the module was configured in the hardware configuration.
