The BT bus is addressed by assigning a logic user number in the I/O
editor of the PLC programming interface WinPCL. Each input core image
storage as well as each output core image storage is assigned its own
logic address.
Each of the two core image storages has a size of 128 bytes, which are
available for the operating devices connected. The number of bytes
assigned in the core image storage depends on the operating device (see
Fig. 5-4).
Type of device Storage assignment in the input/output core image
BTM15
2 additional bytes for each module (except handwheel)
BTM16
BTA20

Fig. 5-4: Storage requirements of operating devices

Depending on the physical order of the operating devices connected to
the BT bus, the addresses of the devices are assigned in the input and
output core image storage without any gaps, according to the storage
requirements of the operating devices. The example (Fig. 5-5) illustrates
the principle of the storage assignment of the BT bus.

Fig. 5-5: Storage assignment of BT bus

Depending on the configuration
2 bytes for digital I/Os (always assigned)
4 additional bytes for handwheel module
14 bytes
6 bytes
Example:
Here addresses 6...17 are assigned to
the BTM15. The addresses are assigned
according to the physical order of the
connected operating devices.
