mixing CoE and mailing

Explain me better .... I have a drive that support CoE .... I can work on it whitout problem ... but it ha have more nice register to read, only is not supported from PDO system .... so think is possible read it with ethercat register data exchange system (EoE I think). But how I can do? need to make a new component derived from "generic drive" one? or need to make a new config file with EoE xml? or can mix a simple csp CoE .xml file with a EoE xml file?

best regards
and thanks in advances for every help

If the PDO's exist, they should be able to be added to your xml file

sorry not well understand ... actually I can move that motor whitout problem .... my machine work!
Only I have some nice register like "temperature register", "torque sensor register", "ethercat status register (like preop, op, safeop, init)", "error type register (not 603F register other one more specific)" that not support PDO, but can be read trought modbus or EoE ..... so you suggest to add standard SDO and PDO in a one only .xml file for EoE comunication?

the above example can work ? (referred to red row):

Attention:

CoE (Can over Ethercat) and
SoE (Sercos over Ethercat)

are both communication layers which are related to the ethercat slaves mailbox communication layer (pre op state) . Both are usable with the lcec.

EoE (Ethernet over Ethercat) is an layer to establish ethernet communication over you ethercat bus (tcp/ip ftp , drive setup software etc..) . if your slave is able to do EoE you can create an virtuall network adapter for direct acces to the slave through your ethercat master. (there is an long thread about Indramat drives and the necessary setup for this, ~3-4 years ago.... )


All these things are not related to process data communication (pdo, sdo) at running state. (ethercat op)

thanks db1981 ..... so in OP mode can or not use CoE AND EoE at same time? CoE for drive motor with usual PDO and EoE only for read some register not possible to read trought PDO?

Example: I use my machine.xml file with SDO and PDO  for preop and than op state .... but need to read reg 1001h udint 16bit (that not support PDO) .... can insert an .xml file for EoE reading?

regards

@db1981 ok find .... you means have a second master or bridge port for EoE comunication only right? so i can have lcec.1.x.myNonPdosReg value right? I well undestand these time? these is the only possibility?

@all .... I find these: fh-soft.de/src/ethercat-userspace.html#Usage     than these:  forum.linuxcnc.org/ethercat/22346-ethercat-hal-driver?start=330

regards

Ok an other solution can be using pyton routines for launch reg_read istance every 500ms so we can update 2 or 3 interesting register whitout using EoE or other complicated stuff like make new one Lcnc Ethercat drive for read SDO  (because that register was object and not pdos entry) .... plus I can read during OP mode i think .... NEW problem, command:



return every time these error on terminal ....



think because bad usages .... how make wrong?

regards

Very interesting reading..

I had common problem of reading some PDO but it did not want to add without cyclic communication over ethercat... there is object for startup but no for any source of read only during cyclic operation....

I am currently pinning myselft here 

I solve .... these is the currect comand (upload instead download) ..

for example and obtain manufactorer custom string

regards

In these case if you would read only at startup (preop) .... see link for read SDOs object .... but personally would check that object sometime ... so prefer send a terminal command like these above and grab value ....

No time for develop EoE comunication ... and upload commend can launch during moovement whtout problem ...
