Fig. 6-2 Allocation of Komm_DB Communication Module (DM255)
D478 of the data module defines which operator terminal is connected to
the PLC. With D478=5, a BT5, and with D478=0, a BT20 is declared. In
the event that this identifier is not entered during the operation of the BT5,
the movement function keys (F1, F2, F5, and F6) will be disabled. In the
case of the CL400 / CL500 controllers, the same condition will prevent the
synchronization result (LED in the respective movement keys) to be dis-
played.
