Every function comprises one or several blocks that are interconnected with one another.
Figure A-5 Example of a block: Motorized potentiometer (MOP)
Most of the blocks can be adapted to specific applications using parameters.
You cannot change the signal interconnection within the block. However, the interconnection
between blocks can be changed by interconnecting the inputs of a block with the appropriate
outputs of another block.
The signal interconnection of the blocks is realized, contrary to electric circuitry, not using
cables, but in the software.
Figure A-6 Example: Signal interconnection of two blocks for digital input 0
Connectors and binectors are used to exchange signals between the individual blocks:
● Connectors are used to interconnect "analog" signals. (e.g. MOP output speed)
● Binectors are used to interconnect "digital" signals. (e.g. 'Enable MOP up' command)
Figure A-7 Symbols for binector and connector inputs and outputs
Binector/connector outputs (CO/BO) are parameters that combine more than one binector
output in a single word (e.g. r0052 CO/BO: status word 1). Each bit in the word represents a
