8.2 Terms Used for motionCAT
8.2.1 Motionnet Communication LSI
There are two types of communication LSI; the center device (G9001) and the local device. The local device
includes the DIO device (G9002), the motion device (G9003), and CPU emulation device (G9004).

DIO device
CPU emulation device
8.2.2 Master Board
This is the board in which the center device is installed. Communications of the motionCAT system is controlled
with this board.
8.2.3 Line
Lines include the serial communication line, communication line, and the transmission line of the center device.
In addition, the ID number of the center device line installed in the master board is called the line number.
8.2.4 Slave
A slave is a unit composed of a communication board and multiple modules (1 to 6 modules). There are two
types; HMG type and HUG type.
8.2.5 Module
A module is the circuit board for assembling a slave. Modules include motion (P, C), DIO (D, T), and analog (A)
modules.
Each of them is identified by a module ID. Module IDs can be set from 00h to 3Fh (0-63).
8.2.6 Module ID
A module ID is an address (ID) to identify each module. It is set with the M ID rotary switch on the communication
board.
8.2.7 System Communication and Local Device Information
This is a communication to retrieve the connection status, device type, and input/output port settings of each local
device.
These pieces of information on local devices are called the local device information.
