18. Tool functions

18.1. Oscillograph

The oscillograph function is explained.
Caution
With the oscillograph, the maximum number of screens that can be opened is limited to eight since this
increases the load on the PC. Keep in mind that memory may be insufficient if many screens which
need memory such as program editors and parameter editors are opened.

18.1.1. Outline

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

18.1.2. Communication method

The communication methods which acquire various internal data from a robot include the following two systems
are among.
18.1.2.1. Ordinary communication
This is a communication method which uses a communication server.
Therefore, it can be used in an environment where connection to a communication server is possible.
The characteristics of ordinary communications are shown below.

18.1.2.2. High speed communication
High-speed communication can use a real-time monitor function to acquire data at intervals of 3.5 msec or 7.1
msec. The real time monitor function cannot be used unless the environment allows the robot controller to
connect with a personal computer by Ethernet.
If you cannot get data from a robot controller, see "Communications (Ethernet)" (4) in "27.1 Q&A".
The feature is explained.
