peakrdl-ethercat-xml 0.1.0

This repository implements a PeakRDL module that generates an ESI description XML for EtherCAT (see ETG.2000 for details) from a SystemRDL file. The generated file only describes register mapping, therefore it should be copied into the main ESI file of the subdevice inside the device tag and after the definition of the sync managers (tag sm).

Structure of XML file

Since the address is only defined in the sync manager configuration, the registers do not carry address information. Instead, you should consider the memory to be a contiguous bit space and get the address of the fields by counting all fields before the one you are interested in. Therefore, if there is a gap between fields, this PeakRDL module fills it with a reserved bitfield space. These fields carry a unique name with schema Reserved_##.

The Index tag relates to the data type. The SubIndex tag is an entry identifier unique to this object (PDO or PDI). It increments on each entry.

Local Installation:

pip install .

Usage Example:

peakrdl ethercat-xml <path/to/system.rdl> -o <output/path>
