3.1 Working with function blocks
The signal flow of the controller can be configured by connecting function blocks. The controller can
thus be easily adapted to diverse applications.
3.1.1 Signal types
Each function block is provided with a certain number of inputs and outputs which can be interlinked.
Corresponding to their functions, there are only certain types of signals at the inputs and outputs:
l Quasi analog signals
– Symbol:
H
– Unit: %
– Designation: a
– Value range: ±16384 = ±100 %
– Resolution: 16 bits, scaling ±16384
¢ ±100 %
l Digital signals
– Symbol:
G
– Unit: binary, with HIGH or LOW level
– Designation: d
– Resolution: 1 bit
l Speed signals
– Symbol:
F
– Unit: rpm (for display, internal representation in [inc/ms])
– Designation: phd
– Value range: ±2 15 − 1
– Resolution: 16 bits
l Angle signals
– Symbol:
E
– Unit: inc
– Designation: ph
– Value range: ±2 31 − 1
– Resolution: 32 bits, scaling 1 revolution ¢ 65536 inc
Only the same signal types can be connected. Thus, an analog output signal of one function block
can only be connected to the analog input of the other function block. If you try to connect two
different signal types, the connection is rejected.
