the pendant belongs not to this system.
i bought it later and in this moment on booting it displays IP class 126 instead of 125 as in the controller.
i must change the Flex Pendant IP later.
i did not give importance to the flex pendant for the moment.
i am focusing on the controller communication issues because the controller does not comunicate proper with the RObot Studio and it should regardless to the flex pendant.
if i press TEST for the communication than i get OK message. when i want to transfer data, than i get that message with connection error give by the not finished booting. this is what i read. Not possible to link as long the booting is not ready. he is feeling the controller as he did not finished the boot phase.
