»Engineer« Lenze software which supports you throughout the whole machine life
cycle - from planning to maintenance.
Code "Container" for one or several parameters used for controller parameter
setting or monitoring.
Subcode If a code contains several parameters, the individual parameters are
stored under "subcodes".
This Manual uses a slash "/" as a separator between code and subcode
(e.g. "C00118/3").
Function block A function block (FB) can be compared with an integrated circuit that
contains a certain control logic and delivers one or several values when
being executed.
• An instance (reproduction, copy) of the function block is always
inserted in the circuit.
• It is also possible to insert several instances of a function block in a
circuit.
• Each instance has a unique identifier (the instance name) and a
processing number which defines the position at which the function
block is calculated during the task cycle.
System block System blocks provide interfaces to basic functions and hardware of the
controller in the function block editor of the »Engineer« (e.g. to the
digital inputs).
• System blocks cannot be instanced in contrast to function blocks.
