1. INTRODUCTION
1.1 Introduction of This Manual
This operation manual is for the users of the data transmitting function of industrial robot MOTOMAN
controller NX100, YASNAC XRC, MRC, MRCⅡ, ERC, and ERCⅡ.
This operation manual outlines the operation method of the personal computer software MOTOCOM32
for data transmission between the robot controller and a personal computer, and at the same time, the
specifications of the supplied data transmission function.
Read this operation manual thoroughly before use.
1.2 Features of Ethernet Communications
The Ethernet I/F board and the “Ethernet” function of the MOTOCOM32 transmit data at higher than
normal speeds.
●High speed transmission
In comparison with transmissions using RS232C, higher speed transmissions are possible with the
Ethernet.

Note : The above transmission speed is the communication speed between network devices, not
including the time used for format check of transmitted data, etc.
●Transmissions between a multiple number of HOSTS
As N:N transmission is possible with an Ethernet cable, the following system configurations can
be prepared.
Note: Refer to paragraph 2.3 “Restrictions” with the following Configuration Examples.
