2.7.3 OPTION_MD
Description
The identifier allows option machine data to be redefined. As delivered, the system uses
MD14510 $MN_USER_DATA_INT[0] to $MN_USER_DATA_INT[3].
If the PLC user program manages the options, the appropriate data words must be provided
in a data block or GUD.
The data is structured in bits. Starting with bit 0, there is a fixed assignment of the bits to the
listed devices, i.e. bit 0 is assigned to device 1, bit 1 to device 2, etc. If more than 16 devices
are managed, the address identifiers of the device groups 1-3 are assigned via the area index.
Note
Converting the value range
The value range of MD14510 $MN_USER_DATA_INT[i] is from -32768 to +32767. To activate
the devices bit-by-bit via the machine data dialog, the bit combination must be converted to
decimal representation.
