Option bits for machine manufacturers and dealers

Distribution of the option bits
The option bits are managed in blocks of 16 bits. According to the default setting, block 3 is
reserved for dealers. This means that machine manufacturers have 48 options and dealers
have 16 options.
The Easy Extend function uses the following machine data to manage options:
MD14510 $MN_USER_DATA_INT[0] to MD14510 $MN_USER_DATA_INT[3]
This assignment of the addresses can also be redefined in the script using the identifier
OPTION_MD so that dealers can specify their own address area. If the dealer wishes to offer
more than 16 options for this machine type, then the blocks not used should be determined.
This must be coordinated with the machine manufacturer.
Block 3 must be programmed in the script using operations to communicate the dealer area.
Further, a fixed device index should be assigned for every device.
Example to redefine any area:
<option_md name="address identifier of the data" index="<index>"/>
index - identifier of the area index:
Mapping the device on the PLC interface
Each device must be assigned a unique index in order to permanently assign devices an option
bit and to be able to access the PLC interface. The areas are permanently assigned using the
attribute option_bit. If an assignment is not made, then the bits and the interface are defined
by the index, which is assigned to the device in the following list:
