For many applications, interlocking logic is required in order to control (open-loop)
the drive inverter. This interlocking logic couples several states (e.g. access
control, plant/system state) to form a control signal (e.g. ON command). Previously
this was implemented using either a PLC or relays. This represented additional
costs for the plant or system. In addition to logic operations, increasingly, arithmetic
operations and storage elements are required in drive inverters which generate a
new unit from several physical quantities. This simplified PLC functionality is
integrated in MICROMASTER 440 using the freely programmable function blocks
(FFB).
The following function blocks are integrated in MICROMASTER 440:
