We have the NI 9144 Slave with a 9401 module. We are using the Integrity RTOS (Green Hills), with the EtherCAT stack from Acontis. No LabView or other Windows software.
Using the Acontis configuration program, EC-Engineer, we have an XML file that is configured for initializing the NI 9144 & 9401.
However, we cannot setup for nibble control of the Digital Input and Output ports. The default is all ports Input.
We have tried to add an Initialize command for 0x2001:0x0 with a setting of 0x2 to program for DI ports 0-3 and DO ports 4-7.
But the response during initialization is that the Object Dictionary for the 9401 does not have 0x2001 defined.
And I do not see it in your XML file for that module. Is it missing?
From your documentation, I know it is stated as a vendor configuration extension. Does this mean that I have to add it to your module XML file?
Do you have experience with EC-Engineer and how to program the modules?
Thank you for your help in this matter.
