Oscillograph

The oscillograph function is explained.
Caution
Since an oscillograph function needs the memory and CPU power of a personal computer, the screen
to open has been restricted to a maximum of 8 screens. If many screens which need memories, such
as program editor and parameter editor, are opened, please keep in mind that a memory may be
insufficient

16.3.1. Outline

The oscillograph can display the graphical representation of a robot's various internal data.
The data acquired from the robot can be saved at a CSV file. By specifying a preservation interval, prolonged
data recording is possible. A program name, an execution row number, and an input-and-output signal are
also simultaneously recordable on a CSV file.

16.3.2. Communication method

The following two systems are among the communication methods which acquire various internal data from
a robot.
16.3.2.1. Ordinary communication
It is a communication method which uses a communications server.
Therefore, it can be used if it is the environment where a communications server is connectable.
The feature is explained.

16.3.2.2. High speed communication
The high-speed communication can use a real-time function, and can acquire data at intervals of
7.1msec.The real time monitor function cannot be used if it is not the environment which a robot controller
can connect with a personal computer by Ethernet.
If you can't get data from a robot controller, please confirm "Communications (Ethernet)" (4) in Chap. 21.1
"Q&A".
