Non-Protocol Communication 
 
Non-protocol communication is used for exchanging data with a robot language 
program and for printing out files. 
The COM1 (RS-232C) port, and Ethernet IP1 and IP2 ports are used for non-protocol 
communication. 
 
The data format for character strings to be transferred between the robot controller and 
the TCP/IP device is as shown below. 
 
Character string + CR (0x0D) 
Character string, character string + CR (0x0D) 
These character strings are based on 
ASCII format.   
ASCII 0x0D (carriage return) is added 
in the character string data.    When a 
plurality of data is transferred, the 
character string is separated by 
 
The functions as described in the simple protocol cannot be used for the non-protocol 
data communication.    Also, response to data received by the controller and timeout 
check are not processed at all. 
 
4.1  Communication with a Robot Language Program 
 
Data communication with a robot language program can be performed using the PRINT 
and INPUT commands.    For more information on the robot language, see "Robot 
Language Manual". 
 
4.1.1  PRINT Command 
 
The PRINT command allows you to send out a specified character string from the 
controller.    The controller transfers character strings or values of variable specified 
by the PRINT command.    The format of the PRINT command is shown below:
