22 Object directory
The OD is a collection of PMX setup and status parame­
ters. A PC or PLC program can change PMX parameters,
that formerly could be edited via the GUI only.
The PMX OD is not the EtherCAT dictionary of cyclic
data objects. The EtherCAT objects are visible to the
EtherCAT master only.
The object dictionary is imple­
mented in firmware version 3.02 and higher.
22.1 Accessible Data Objects
The object directory (OD) contains all relevant parame­
ters of the PMX plug-in cards (except for the fieldbus
card) and the computing channels that have been
created in PMX. Objects for changing the operator level
are also included.
All other available device parameters can be found in the
PMX command set (section 21), the dotNET-API or the
device description files of the fieldbuses (section 16).
The marked parameters in the screenshots give an
impression of the accessible data objects. Data objects
that are in any case transferred periodically via the PC
Ethernet interface or fieldbus are not visible in the OD.
