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 has a certain number of inputs and outputs, which can be interlinked.
Corresponding to their respective functions, only particular signal types occur at the inputs and
outputs:
l Quasi analog signals
– Symbol:
– Unit: %
– Designation: a
– Value range: ±16384 = ±100 %
– Resolution: 16 bits, scaling: ±16384 ¢ ±100 %
l Digital signals
– Symbol:
– Unit: binary, with HIGH or LOW level
– Designation: d
– Resolution: 1 bit
l Speed signals
– Symbol:
– Unit: rpm (for display, internal representation in [inc/ms])
– Designation: phd
– Value range: ±2
15
− 1
– Resolution: 16 bit
l Angle signals
– Symbol:
– 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 with each other. Thus, an analog output signal of one
function block can only be connected to the analog output of the other function block. If two different
signal types are connected, the connection will be rejected.
