Fig. 3-49 Example for directly selecting FF1 via DIN1 and FF2 via DIN2
Direct selection + ON command
When this fixed frequency is selected, the fixed frequencies are also directly
selected whereby the selection is combined with the ON command. When this
technique is used, a separate ON command is not required. The following is
obtained essentially analog to the example shown above:
a) Standard method
→ P0701 = 16
b) BICO method → P0701 = 99, P1020 = 722.0, P1016 = 2
Binary-coded selection + ON command
Using this technique up to 16 fixed frequencies can be selected using 4 control
signals. These 4 control signals are either entered via digital inputs or a serial
communications interface. The fixed frequencies are indirectly selected using the
binary coding (refer to Table 3-23,
→ e.g. selected using the digital DIN inputs),
whereby the selection is combined with the ON command.
