hello Rahied:
I've an another quesiton: how could you know there is a method "add" for proj? I used dir(proj) there was not "add" method listed.

thanks alot

Hi, etamgul,

A scripting interface for the I/O Mapping is currently scheduled for the upcoming V3.5 SP8 release by the end of the year. (See CDS-37756).

(Please note that the schedule may still change when other, more important issues arise.)

By plugging the device via a script a generated name is given to its structures and accessable variables (e.g. "%QX7.7", similarly when one has only plugs the device) but in GUI, I have the chance to map those addresses to variables.

Is there a way to configure the plugged device configuration and I/O mapping ("xxx Configuration" and "xxx I/O Mapping" tabs)?

I have some ADC/DIO/DAC "pins" configured and would like to map their variables and structures to one of the PRGs stored variables.

Hi Rahied,

The Device is an EH_IOCA (with underscore).
The name of the plugged devices cannot have a space. You should use e.g. "%s_%d" as device name to make them unique.
Your import file (.txt) should have no empty lines at the end.

Attached an example import file and script for plugging the modules in the Hitachi EH-IOCA EtherCAT slave.

Maybe not perfect or complete, but for me this works.

It seems you did mix tabs and spaces in the attached script. The error message actually tells you the location of the problem in the source file.
Python generally interprets tabs according common standards with 8 characters, while your editor seems to use 4 characters of tab with.
Generally, the python community strongly suggests to not mix tabs and spaces in source files:
PEP 8 -- Style Guide for Python Code
You should use an editor which can display tabs and spaces, so you can see the problem. Here is how it looks in my editor using 4 characters tab with:
And here's how the Python interpreter "sees" it using 8 characters tab with:
