Master Communication Interfaces
The basic functions of master communication apply to each type of
master communication, in the case of IndraDrive devices to SERCOS
interface, field bus interface, parallel and analog interface.
Features
All variants of master communication supported by IndraDrive have the
following functional features in common:
• address assignment
→ communication address to be freely parameterized (via master
communication, serial and control panel) via parameter P-0-4025,
Drive address of master communication
• command processing
→ drive commands to be externally activated (via master
communication, serial and control panel)
• device control (status machine)
→ individual status machines for master communication and device
• According to the variant of master communication, the master
communication status machine has different functionality and
complexity. The communication-specific states are distinguished
and mapped to the status words of the corresponding master
communication (e.g. for SERCOS: S-0-0014, S-0-0135).
• The device status machine is independent of the variant of master
communication and maps the device-specific states to parameter
S-0-0424, Status parameterization level. We always distinguish
operating mode (OM) and parameter mode (PM).
• extended possibilities of control
• signal control word/signal status word (S-0-0144, S-0-0145)
• multiplex channel
See section "Possibilities of Control/Additional Functions" in the same
chapter
Note: The status machine of the master communications is briefly
outlined in this section; it will be described in detail, i.e.
including the individual status transitions, in the main chapter
of the respective master communication.
