Siemens SINUMERIK 828D Commissioning Manual

8.3 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:
0: Device 0 to 16 (default setting)
1: Device 17 to 32
2: Device 33 to 48
3: Device 49 to 64
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:
Index MD14510 Data block Device designation
0 $MN_USER_DATA_INT[0] Bit 0 DB9905.DBB0 Device 1
1 $MN_USER_DATA_INT[0] Bit 1 DB9905.DBB4 Device 2
2 $MN_USER_DATA_INT[0] Bit 2 DB9905.DBB8 Device 3
3 $MN_USER_DATA_INT[0] Bit 3 DB9905.DBB12 Device 4
.... ... ... ...
47 $MN_USER_DATA_INT[2] Bit 15 DB9905.DBB188 Device 48
48 $MN_USER_DATA_INT[3] Bit 0 DB9905.DBB192 Device 49
49 $MN_USER_DATA_INT[3] Bit 1 DB9905.DBB196 Device 50
.... ... ... ...
62 $MN_USER_DATA_INT[3] Bit 14 DB9905.DBB248 Device 63
63 $MN_USER_DATA_INT[3] Bit 15 DB9905.DBB252 Device 64
