8.3 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.
8.3.1 Signal types
Every function block has inputs and outputs for connection withcorresponding signaltypes for each
function:
• Quasi analog signals
– Symbol:
H
– Unit: %
– Designation: a
– Value range:
± 16384 = ± 100%
– Resolution: 16 bit
• Digital signals
– Symbol:
G
– Unit: binary, with HIGH or LOW level
– Designation: d
– Resolution: 1 bit
• Speed signals
– Symbol:
F
– Unit: rpm
– Abbreviation: phd
– Resolution: 16 bit
• Phase signals
– Symbol:
E
– Unit: inc
– Designation: ph
– Value range: 1 rev. = 65536 inc
– Resolution: 32 Bit
The signal type of the output and input must be the same for a proper connection. Thus, the analog
output signal of one function block can only be connected to the analog input signal of the other
function block. If two different signal types are connected, the connection will be rejected.
