18. Tool functions
18.1. Oscillograph
The oscillograph function is explained.
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.
Table 18-1 Ordinary communication
Item Explanation
Maximum number of
data held 30,000
(About 50-minutes can be obtained at a data acquisition
interval of 100msec.)
Acquirable data types Fixed (See 18.1.3 Acquirable data )
Data acquisition interval 50, 100, 200, 500, 1000, 2000, 5000, 10000, 30000msec
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 Etherne t.
If you cannot get data from a robot controller, see “Communications (Ethernet)” (4) in “27.1 Q&A” .
The feature is explained.
Table 18-2 High speed communication
item explanation
Maximum recording data
80,000 (About 9-minute acquisition possible
）
Acquirable data types Maximum of 4 data selection (See 18.1.3 Acquirable data )
32 points of a continuous signal (IN/OUT) can be acquired
Data acquisition interval CR800 series : Maximum of 3.5 msec
CR750/700 series : Maximum of 7.1 msec
Robot software version CR800 series : All versions
CR750/700 series : S4b, R4b or later
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.
Caution
