Hello. Iquestions regarding a OSP U100L that is installed on a used machine that I received. I have no previous knowledge on Okumas.

1)
I would like to change the language of the OSP U100L. It is necessary to be done by Okuma "disks" or can it be done by parameter change in a similar way as a Fanuc?

2)
What communication with the machine is possible to send and receive programs? I can see a disk unit (diskette ?!) and a RS232 port. What do you people use? What procedure (resumed)?

3)
The other question is regarding the logical of the controller. Where can I see the ladder in real time and what do I need to edit it and save it on the machine? This is particular important to me as I need to tune the machine behavior.

Many thanks. If you do not know the answer to all, please reply to the one you know as I am greedy for info.
